- How consumer units work / distribution board
This electrical video I show how a electrical panel - consumer unit works and show a variety of components within the consumer unit and how they function within an electrical system.
I go over the main switch, rcds, mcbs, rcbo, surge protection devices and arc fault devices.
I also cover how the power gets too the property and go over the different earthing options and why the earth wire is installed.
Really found this more instructive than other CU videos I've watched and now will understand the electrician more when he comes to swap out my old fuse box to a new consumer unit. Thanks
Brilliant breakdown, this should be shown to all learners very early on. Would have made so many things so much clearer to me! Thanks man, I hope
You’re well 👍🙌🫡
Fantastic tutorial, thank you mate
No problem 👍
it looked like spaggetti to me before this lecture Thanks now I feel competent in electrician
Happy to help
A really interesting video, particularly how it illustrates how differently electrical wiring is done in the UK vs. here in Canada and the US. Quite literally, nothing is done the same! I hadn't even heard of the term "consumer unit" (we call them electrical panels), let alone RCDs (we call them GFCIs, but they are always combined with a circuit breaker, or in the outlets themselves - we don't have the concept of one RCD/GFCI protecting multiple circuits) , MCBs (they are just called breakers), RCBOs (this is really what our GFCIs are more like), etc. Even our meter connections are done differently - we don't have a main cut out fuse at the house - it's at the supply transformer, as is the isolation switch, typically. We don't use ring circuits (I don't think they are even allowable by code); all our circuits are radial. Our panels are also built quite differently (less configurable by the end user), probably at least partially because we use split phase 120/240V instead of a single phase 240V. Just goes to show how different two systems can be to solve the same problems!
Yeah I find it really interesting how different countries have there own way of doing things. I think the uk is one of the few countries that still do ring circuits and started in the 1940s. I think it was to do with being able to use small diameter cable on a ring as opposed to a radial and therefore reducing materials and cost during war time. I appreciate you taking the time out to watch the video and thanks for the comment.
Great video mate im learning to be a spark so these vids are really good, currently seting up my own rig at home so understand it better, are you a spark by any chance. love the milwaukee gear you have. keep it up
