Hi everyone and welcome to the first of several CPD training sessions we have in collaboration with Schneider. Thank you. I can see the chat people joining. Hi everyone. Thank you for joining today. Thank you for your time. Just so we're aware today is a pre recorded session. We do have Marius here today in the background who can answer any of your questions you have. You may have in the chat. So please feel free to ask questions as today's session goes on again. Hello. Everyone. Hello there, Mick. Hello there, Dominic. Hello there, Gary. Thank you all for joining us today for a CPD session and the first of several so please keep an eye out for that we have several more coming along over the next couple of weeks time. Again, in case you have just joined today is an on demand session. So this has been pre recorded, but we do have an expert here Marius who's here to answer any questions whilst today's session is played. So what I'll do is I'll play the recording now again. Enjoy. So today we're going to cover the fundamentals of bus bar and electrical distribution. That's made up of what is bus bar and why we choose bus bar and electrical distribution distribution concepts and the safety standards relating to bus bar and its installation. We're then going to look at the five steps to building a bus bar solution architecture and design principles and then we're going to follow it up by connectivity and remote monitoring and planning for the future with your bus bar installations. If you do have any questions, please feel free to drop them in the chat and myself or one of my colleagues will pick them up as we go through the presentation. Now, no matter the type of business, reliable power is essential. All of our sectors require reliable power. Healthcare demands it to save lives, businesses to keep trading, oil and gas to provide constant supplies and data centers to keep the digital world's lights on. And bus bar plays a key part in this. Now we have two key applications for bus bar. That's distribution bus bar and feed a bus bar, which may also be known as transport bus bar distribution bus bar distributes power from a central location such as a switchboard to multiple outgoing connections using tap off units. Whereas a feeder bus bar supplies a switchboard from a transformer as well as interconnections between switchboards across the site. So they won't have any tap off points. It is purely just bus bar connecting one load to a switchboard or from a transformer. Now bus bar comes in ranges of 25 amps up to 6300 amps, and this offers an alternative electrical distribution system to cabling. Bus bar is usually made out of copper or aluminium conductors, which are encased in steel or resin casing, depending on the IP rating. And we can make multiple connections to the bus bar with tap off solutions containing fuses, modular MCBs and RCBOs, MCCBs, metering and smart connections. Now I just noted that copper and aluminium are our two main types of bus bar. Now the classic copper bus bar provides a smaller sized bar due to having an increased conductivity. Whereas the increased use of aluminium bar that we're now seeing offers similar performance levels, but with a larger profile bar due to decreased conductivity. So it's important to note that copper bus bar for 4000 amps will often be smaller than the aluminium alternative for 4000 amps. However, it is important to note that aluminium bus bar can be up to 40% lighter than copper, which makes it easier for installation and has increased manoeuvrability, especially when you're working in tight areas or across the largest site. And the performance of the bus bar trunking, whether that be aluminium or copper bus bars, will be the same for any given specification. So when writing specifications, this performance or the electrical performance will be the same. And this performance is dictated by compliance with the current national standard of IEC 61439-6. So this encompasses factors such as dielectric properties, impedance, ingress protection, mechanical strength, short circuit width strength and many others. And we'll be going into that a little bit later. So that was a little bit of understanding the basics of bus bar and sort of the very basic of what it is and how it's made up. But we have a full bus bar solutions overview here, which really demonstrates the full width of wallet really and how bus bar can be fitted into every electrical distribution system. So we have lighting and low power distribution bus bar, which is from about 25 amps to 40 amps. And this would be used for lighting in a warehouse or some small power in a retail outlet. We've then got power distribution from 40 to 160 amps. And then we have horizontal and vertical distribution for 100 up to 1000 amps. So that's when we're starting to get into risers and much larger horizontal runs. We then have some specific bus bar architecture for EV charging and for data centers. Good to note data centers is open track as well for use in the white space. We'll touch on these two areas a little bit more later in our architecture and design principles area. But it's important to note they run up to about 630 amps. We then have an increased power transmission and distribution from 800 amps up to 6300 amps. So that is used for that transport bus bar, that feeder bus bar that we touched on earlier. And then we have power transmission for outdoor and harsh environments, which is similar to the power transmission and distribution bus bar. However, it's IP six X rated. So why should we choose bus bar for our electrical distribution? So as we can see from the image shown in the slide, bus bar can be utilized in all areas of electrical distribution, whether that be connecting the transformer to the main switchboard, the switchboard to the main panels. Connections from the switchboard to other panel boards or distribution boards and distribution bus bars, sorry. Rising bus bars supplying power to multiple floors through risers. Or for final distribution, supplying lighting and small power. The flexibility of bus bar allows for an end to end solution for our electrical distribution needs. So you might be thinking, well, I use cable traditionally. Why should I move move over to bus bar or utilize bus bar more in my electrical design work? But it's important to note that distribution bus bar, the contractor with distribution bus bar, the contractor can achieve savings with the spectrum of materials such as cable trays and multiple fixings, as well as the labor costs associated with multiple runs of cable. Bus bar also has a reduced installation time since bus bar trunking requires less fixings per meter run than cables do. Multiple top off outlets on distribution bus bar allow for flexibility to accommodate changes in power requirements subsequent to the initial installation. So that's all to do is future proofing. Repositioning of distribution outlets is simpler with tap off units and the system is easily extendable. These engineered products also have a proven performance and are verified to recognize international and national standards. And bus bar is also much more aesthetically pleasing in areas of high visibility, such as retail outlets. When we look at feeder bus bar, we look at the greater mechanical strength. We have greater mechanical strength over long runs with minimal fixings resulting in shorter installation types. Feeder bus bar also replaces multiple runs of cable with their associated supporting network such as the cable trays and the clips. Feeder bus bar is much easier to install compared to that of multiple large cables with the associated handling problems. Feeder bus bar also requires less termination space required in switchboard, something that we'll see in a couple of slides time. Feeder bus bar also has verified short circuit fault ratings included and as well included with the joints. Feeder bus bar will take up less overall space in the network due to bends and offsets that are required in the sorry bends and offsets that can be installed. Feeder bus bar is also required in the remote, whereas with cables, when you're looking at 90 degree turns, the curvature you require for that takes up much more space. A cable jointer is also not required for bus bar as it can be bolted together. Buzzbar trunking systems can be dismantled and reused in other areas. Whether it's the same factory or a new factory, you can reutilise your buzzbar. Buzzbar trunking systems also provide a better resistance to the spread of fire. Again, something that's very important at the minutes of fire regulations, and we'll touch on that later. And voltage drop in the majority of cases while utilising buzzbar is much lower than the equivalent cable arrangement. So we touched on installation time there. So when we look at buzzbar, it is modular components that provide a quick installation using a plug and play model, simply just bolting it together or sometimes clipping it together. This provides power as the installation is completed, and it is much easier to connect and add loads to the pre-assembled tap-off connection points later on in the buzzbar's life. And it's much safer for mechanical and electrical jointing. So if we look at cable, it's labour intensive. You have to install cable ladders and cable trays where required. And there are many more working steps, such as cutting, scaling the cables, connecting the luminaires and mounting sockets. Now, this is time consuming, and you have complicated cable connections which take up more of your time. And if you need to make further modifications later down the line, it is much more complex. So if we just have a look at the bottom left-hand side of the slide there, we can see there that on a buzzbar installation, we've got two of our workers installing that buzzbar network. When we look on the right-hand side, you could have five or more people used in installing the cable runs. So in terms of labour costs, you've more than half the workforce there. Now, if we're looking at comparative investment, we're going to have a look here at comparing a cable installation to that of a buzzbar installation. So when our number of connection points is over six, it says branching points there on the graph, equipment and labour becomes more cost-effective to install a buzzbar solution than it is to install a cable network. Now, this example is of a 400-amp electrical power solution, but you can see here that buzzbar is more cost-effective over time, especially on those larger jobs. And as we touched on previously, on the right-hand side of the slide, where a buzzbar installation requires two installers to come and install the components, cable running could utilise five people to run, joint and clip the cable throughout the entire install process. Now, if we look at space saving for buzzbar over cable, we touched on this earlier with the less joints and the less space in the switchboard. But if we look at a switchboard with a buzzbar connection point here, so the total square area is about four metres squared. That's with a total load output of 1600 amps. There's one output from that switchboard. It's one metre long and we utilise a flange or an interface panel connection to join the buzzbar to the switchboard. When we look at the cable alternative, so that's with the same load of 1600 amps, that switchboard has increased to 16 metres squared with 36 output cables and a six metre length. So, buzzbar can help reduce the size of the main switchboard. And as the number of power connections increase, the footprint of the panel will still be minimal compared to that of using a cable connection. So, if you're connecting two buzzbars, you've got two 1600 amp buzzbars, you're only doubling the size of that switchboard on the left hand side, whereas the one on the right hand side would again double to make it even longer. And with these less terminations required on the switchboard, utilising a flange and interface kit, it gives you one central connection point for all of your connected circuits. So, not only are you saving on the size of the switchboard, but the switchgear inside of the buzzbar is massively reduced in cost. And the example picture on the right hand side there, demonstrating a buzzway for four buzzbar for 4000 amps or the cable alternative, which utilises 42 copper cables at 240 mil. So, there you can see that buzzbar is about a third of the size of the cable trays and all the cables running really demonstrates how much smaller of a footprint of buzzbar can be compared to that of a cable installation. So, distribution networks. So, in this section here, we're just going to be talking about how we can utilise buzzbar and cabling together to build the most effective distribution network for your project. So, when we're looking at a centralised distribution network on the left, the purple is cable trays. So, you can see we're running multiple runs of cable from the main switchboard out to other distribution boards or panel boards. And then there's further cable trays that are then going out and feeding the final loads. In this example here, it is machinery. The fixed installation as well demonstrated here makes it harder for future proofing the site. So, if we need to move one of these machines, we may need to run a new cable back to the panel board and re-terminate it. Or we may need to shorten cables as we go along. If we look at the decentralised distribution network on the right-hand side of the slide, we've still got that switchboard at the top. But as you can see, it's much smaller than it was before. It's about a third less of its footprint. So, that buzzbar is still being interconnected from the transformer. This is now being done overhead. And then from that switchboard, we've got two buzzbars coming out of it. So, these are connected via cables. So, we're not connecting the buzzbars directly to the switchboard in this example. We are still utilising cable. But instead of the multiple runs of cable we had before, we've now just got two, one feeding each buzzbar. And then from that buzzbar, we're going along the full length of the manufacturing plant here. And then that is then feeding smaller buzzbars. So, it's supporting the future proofing of the site as well. We can easily disconnect tap-off units from the buzzbar and move them around if we need to move machinery. And it's important to note that we've lost the one panel board and the distribution board because protective devices can fit directly into the tap-off units, even for larger loads. So, that means that we're not having to buy a panel board, get it installed, make all the connections. We can actually just fit the protective MCCB or MCB onto the buzzbar itself inside the tap-off unit. So, safety as standard. Now, we're just going to do a very high-level overview here of some of the safety standards that buzzbar has to conform to, as well as fire ratings and some other key points as well. So, buzzbar must meet the requirement of IEC 61439-6, as well as IEC 61439-1. So, 61439-1 contributes to the achievement of safety, continuity of service, and compliance with end-user requirements. And specifically, the dash 6 relates to the construction of electrical LV buzzbar trunking systems. So, in these standards, I've just picked out 10 key points here. We've got voltage stress withstand capacity at the current carrying capacity of the buzzbar. The short circuit withstand protection and the protection against electric shock. We also have to have a key focus on the protection against fire or explosion hazards. The maintenance and modification capability of the buzzbar. The electromagnetic compatibility of the buzzbar. The capability to operate the electrical installation. And the capability to be installed on site. And the protection of the assembly against environmental conditions. So, in that environmental conditions piece, we are going to look at IP ratings in just a second. But another key point to note is the IK rating, which is the mechanical strength of the buzzbar. So, all buzzbars will have an IK rating. And this mechanical strength relates to how strong the buzzbar is if someone were to hit into it, possibly with a piece of machinery or knock it. And how strong is that? But the IP ratings, we see most medium to high power buzzbars complying to IP 55, which is when equipment is protected from dust and low pressure water jets from any direction. We also touched on harsh environments earlier, such as marine and nuclear. An IP 68 buzzbar is used as FISA buzzbar in this area. So, equipment is dust type and can withstand being submerged in water over a set period of time. And this example on the right hand side here is cast resin buzzbars. So, these buzzbars are precast and then when they're jointed on site, they're cast together so that they meet this IP 68 rating. Now, the fire regulations. Now, following, there's been some recent changes in fire regulations for buzzbar, but they all break down to fire reaction, fire resistance, as well as circuit integrity of the buzzbar. So, if we're looking at fire reaction, this is characterized by the ability of a material, such as a buzzbar, to spread a fire. So, we'll be looking at flame spread, flaming droplets, the heat released from the buzzbar, as well as the smoke production and its opacity and toxicity. We then have a look at fire resistance of the buzzbar, which gives us information on the time during in which the construction components maintain their mechanical and insulating properties during a thermal event. And the main risk here consists in the spreading of the fire from piece to piece of the buzzbar. Finally, the circuit integrity, which is referring to the operability of the electrical circuit during a fire or whilst a thermal event is taking place. So, when a supplier, when you go out to a supplier, they should be able to provide you with a solution that meets these requirements. Okay. And they can provide you with the information to make sure that the buzzbar installation will meet the fire reaction, fire resistance and circuit integrity requirements. Now, we do have a buzzbar, which is relating to understanding the standards, specifically with buzzbar installations relating to fire regulations. Now, this is an accredited CPD. However, we're currently updating the CPD to the latest standards that have been released. And that's as of the 24th of February, 2025. So, let's have a look at the five steps to building a buzzbar solution. What do you need to make your electrical distribution network work? So, first, we've got feed units and end caps. Now, feed units connect the buzzbar solution to the existing electrical distribution network. These units can bolt directly into a switchboard or be wired via a cable from an upstream protective device. Now, as you can see on the right-hand side, we've got some examples here of some feed units. And they come in a variety of types and sizes depending on the buzzbar rating and connection type. So, smaller feed units, as shown at the top, will be connected via a cable. Whereas, the example on the bottom left is a buzzbar flange, which bolts directly onto the switchboard, allowing for a direct connection to the upstream protective device. And it is important to note that these units must be protected by a suitably rated upstream protective device, whether that be an MCB, MCCB, RCD or a fuse. So, then looking at the run components. So, this is what's making up the bulk of your buzzbar installation. So, these buzzbar lengths or run components build up the bulk of your buzzbar solution. The width and height of buzzbar lengths vary depending on the rating and type of buzzbar. And these lengths of buzzbar come in standard sizes such as 1, 2, 3 and 5 meters off the shelf. However, engineered buzzbar can be designed to suit various applications with custom lengths and ratings available depending on your needs. So, the examples we've got on screen here. The top buzzbar there is a small lighting power, which you'd often see in warehouses and lighting distribution systems. We've then got a medium to high powered buzzbar there with the tap-off units. And then finally, at the bottom, we've got an example of a cast resin buzzbar. So, that's the IP68 rated buzzbar. And here's an example of it going through a wall with a fire barrier. Okay. We then have to look at changing direction with our buzzbar systems because we all know that buzzbars don't just run in a straight line. And it is important that there is flexibility within your buzzbar solution, ensuring that you can get a continuous run of bar without interruptions. So, various fixed angle brackets and flexible joints are available for various buzzbar types. And I think it's key to note here that as a buzzbar becomes higher rated, the number of flexible joints available on the market reduces and we move over to a much more fixed joint being used. And this is where engineered solutions and designs come into play more with custom fixing joints being designed to suit your needs. So, we've got an example here. So, we've got some fixed brackets top left and bottom right. They're showing some fixed pre-manufactured joints you can get off the shelf. And then we've got some flexible joints as well as well. So, the bottom left shows a longer flexible joint going around a steel beam. And then the top right, we've got a flexible corner joint which allows you to turn your buzzbar. We then need to look at the fixing systems available for buzzbar. So, these fixing brackets ensure that the buzzbar solution is secured in place after installation. So, there are various options for fixing brackets such as hanging from steel wire, strut, all thread or being bolted directly to the wall or ceiling. So, we've got some examples here on the screen. The top two are for a much smaller bar and those can be connected utilising steel wire or thread or strut. The solution, the fixing system solution on the bottom right is for when we're mounting buzzbar to a wall. And this can just sort of run around a building and then we can take the various tap-offs off. And then bottom left is an example of a rising buzzbar bracket. So, this is what we'd find in feeders and risers going up and down the side of a building or inside a building, sorry. And then finally, I do one of the most important parts of your buzzbar solution is the tap-off units. The tap-off units allow for the power to be distributed out to the individual final loads. They'll be bolted or clipped directly onto the buzzbar links in dedicated positions. And these devices could be as basic as having fuses or a simple MCB device inside them. Or we can go into bigger tap-offs that utilise MCCBs or direct bolt-on distribution boards for easier connections. And these tap-offs will come in a range of ratings and sizes depending on individual applications. Now, as per IEC 61439-6, it's important to note that tap-off units are arranged to be non-reversible to ensure that they can only be connected to give the correct phase rotation. And that tap-off units are arranged to connect the protective circuit before live conductors during installation and disconnect the protective circuit after the live conductors while being removed from the buzzbar. This ensures that the installer is safe when adding tap-offs onto the buzzbar system. So we've got a few examples of tap-off units here. On the top left, we can see a simple fused supply. They're used on lighting and small power boards. The top right, we've got a modular plug-and-play model here. So where we've got a piece of DIN rail with an incoming supply. Here we can fit MCBs, RCBOs, RCDs, as well as metering and other smart connections. The bottom left, we've got an MCCB tap-off box there where we can fit up to a 630-amp supply. And then that can be connected to the final load. And then bottom right, we've got a open track tap-off unit. So these are utilized much more in data centers, online white space, but we'll touch on that later. It's important to note that these tap-off units can connect anywhere along the run of buzzbar. So architecture and design. Well, exactly how do we see buzzbar utilized in both vertical and horizontal designs? And then some specific architectures as well, where we're seeing a real growth in buzzbar use at the minute. So horizontal and vertical design. So for horizontal installations of buzzbar, it allows for a common connection point for multiple electrical circuits across a distribution network. And the installation of horizontal buzzbar ensures space optimization and ability for easy transformation and future proofing of your electrical distribution network. And vertical buzzbar is very much the same. This rising buzzbar solution enables easy access to power within a riser without the need for multiple cable installations. And this single buzzbar solution can reduce cost and power loss while increasing the power availability in a smaller space. Now, I think we all know the constraints of especially new construction and existing construction with space limitations, especially in riser. So being able to install a buzzbar system straight up a riser really allows you to utilize the space to its maximum. And then we also have closed track and open track buzzbar. So most of you will more than likely be familiar with closed track buzzbar distribution systems. It's the most common form of buzzbar we find. So tap offs can be fitted into the fixed predetermined locations along the length of the bar. And these are fixed. So they're, you know, you can add a tap off at a tap off point, but that is a fixed location. Whereas when we look at open track buzzbar, we are able to fit the tap off units anywhere along the run component of the buzzbar. So we see this open track buzzbar commonly found in white space buzzbar installations, for example, data centers. And this allows for flexibility and future proofing of the system as you're able to install these tap offs at any point along the run component. So talking about data centers, it's important to note how important buzzbar installations are to data center architecture. So we know that information technology is undergoing constant change at the minute. And we're still not too sure what the future servers will be like, as we're currently having a massive boom in data centers across the world. So we can ensure that an effective. So ensuring you use a buzzbar effectively in a data center white space allows you to have this flexibility for the future. We have to make sure that the installation is under control and that the power supply must be controlled, ensuring that the buzzbar solution is integrated with connected products and is a proven design that works. And we often have to make sure that these data center architectures are upgradable and scalable, ensuring that the open track design provides great flexibility for both first time installation and later upgrades, allowing us to add or relocate tap off units easily with limited downtime and cost. So as you can see on the picture on the right hand side there, our data center servers are dual. They've got a backup supply and a main supply. So on the left hand side of the image, we've got our main MV switch panel going through a transformer, possibly through to another switchboard. And then this switchboard is filling out for panel and then out to the white space buzzbar. And then we've got the same or similar configuration on the other side. So having this white space buzzbar allows us to make these connections easily without much interruption to the other servers that are currently operating. Sorry. And this is sort of mapped up here. We've got a bit of a schematic example of the data center architecture. So we've got the permanent and the backup supplies that are feeding each of the racks. And then this is ensuring that the power is staying on to these servers at all times. And another place we're seeing a big boom in buzzbar at the minute is in EV charging architecture. So at the minute, if we've got an existing car park where we're looking to install EV or a new car park where we're looking to install EV, there was a lot of civil's impacts with this. So whether that's digging up part of the car park to install EV charges and run the cables to them. Or just general reconfiguration of a car park so we can fit in all these charges. There was a much there was a large civil's impact. Now, this is what we call a centralized distribution system if we were running with cables. However, we're now seeing an increase in decentralized distribution, utilizing buzzbar to feed EV charging stations. So on the map here on the image, you can see how instead of running possibly 10 cables out of the switchboard on the left hand side, under the road and through to the car parking spaces and each cable feeding one or two EV charges, we're now able to run one cable under the road that is then going to be feeding an array of charges utilizing an overhead buzzbar design. This minimal civil's impact will often save time and cost on the installation as well as you are installing less cables. And it doesn't have to. You still don't need to dig up the road. If we look at example four on the right hand side, you can see how the buzzbar is being fed directly from a building. So there's actually been no need for any civil's work there. And it's been much easier to install the buzzbar solution along the length of the car parking spaces with minimal disruption. So I think we'll hear the words connectivity and remote monitoring a lot at the moment. It's important that we are connected, managing energy, but also being able to remotely monitor our systems for the climate and thermal events and to send us alarms if something unusual is happening. So when we look at energy metering, it's very important that we can track our consumption and ensure we are being as sustainable as possible throughout all of our installations. Now, this can be achieved either through metering inside the switchboard or inside the individual tap-off units, allowing you to break down the energy consumption or the final loads. And these meters can then be connected up to a building management system, which helps us to analyze energy consumption and power quality throughout our electrical distribution network. So as you can see on the slide, we've got some meters there being fitted directly in the switchboard. This could then be connected to a flange for a buzzbar, which is then going out and feeding a high-powered buzzbar. And then we've got a smaller meter here that can be fitted into our modular tap-offs, which allow us to analyze the energy consumption on final distribution loads. And I also touched on remote monitoring and the importance of monitoring ambient temperature and looking for thermal events at all times. So it's important for us to remotely monitor what is going on with our electrical distribution system. And thermal monitoring is a key part of this. So we can utilize thermal sensors inside switchgear to identify an increase in temperature, which could be caused by a fault resulting in an alarm being set off. Now this would then send a signal to us and allow us to safely isolate the buzzbar or a final load before a thermal event takes place. So fitting these thermal sensors not only allows us to monitor the ambient temperature of the buzzbar, but one connected to a building management system can send us pre -alerts and alarms so we can be proactive rather than reactive. And all this, as I mentioned previously, links up to a building management system. So as you can see here, not only have we got energy meters, we've got water and gas meters connected through Ethernet or Wi-Fi, Modbus, analog and digital IOs, as well as wireless devices as well, such as our thermal sensors. And all these connect back to a data concentrator that connect to a BMS that allow us to have a full view of all of our connected products in our system. And finally, we're going to touch on planning for the future here. OK, so we've touched on a lot today how buzzbar installations are future proofed. They're ready for the future. They're easily extendable. And you can add tap offs at later dates. But what does this really mean, especially relating to sustainability? So it's important to be sustainable in today's day and age. And that's why buzzbar is reusable. Now, buzzbar installations are designed to be reused if site layouts change. Run components, feed units, tap offs, they all disconnect easily so they can be utilized elsewhere, whether that's on another existing buzzbar installation or whether actually we're just having a move around of the factory and we're going to run this buzzbar elsewhere. We can also expand the existing installation. So buzzbar installations are designed for future expansion. It's easy to purchase new compatible parts which can be added on to the existing installation after taking off the end caps. And this could be with older or newer buzzbar and really gives you that flexibility. And also on the expansion of existing installations is the utilization of tap offs. So these tap off units, depending on the size and rating of the bar you're using, can really go up to high amperages, which allow you to tap off onto other buzzbars, other machines, other final loads. And having this flexibility allows you to expand your electrical distribution network quite often with minimal work. And finally, it's important to note that buzzbar components are around 90 to 95 percent recyclable across all of us, all of the suppliers. And buzzbar comes with product environmental profiles or product environmental passports. You may have heard of them before. And these really break down what materials are inside our buzzbar installation. Sometimes it can relate to a specific range of buzzbar or specific products, depending on what they are. And this tells us the environmental impact we are having by purchasing this product, installing the product, the carbon footprint of the product. And this is something you can't easily obtain with cables. So I just want to say thank you for listening today for our buzzbar on the fundamentals of buzzbar in electrical distribution. If you do have any questions, please feel free to drop them in the chat. As I said, myself or one of my colleagues will be happy to reach out. On that note, I just want to say thank you for listening. Have a wonderful rest of your day. Thank you, guys. Thank you for joining us today. Really, really good session there. Thank you for joining us. I'm seeing some really good questions as well in the chat. I just want to say as well, a massive thank you to Ben, the speaker today, Marius and Schneider for sharing their expertise with us today. And thank you very much for also joining us this sunny afternoon. As mentioned in the chat at the start of today's session, Schneider will be providing the CPD certification for attending today's session. So please keep an eye out on your email inbox for this. Just so you're aware, we'll also be running another CPD session provided by Schneider next week titled Introduction to BMS. BMS. In fact, what I'm going to do, I'm going to put a link to the registration page there for you guys to hopefully join us as well next week. Also, more and more training coming up. We also have a installer training this Thursday with BG Sync Energy covering home energy management. I'll also put the registration link in the chat now as well. So hopefully I'll see you guys either Thursday or next week for even more training. I hope you have a fantastic rest of your day and see you soon. Bye bye.
