CU Installation, Step by Step

funniest forum's members

Hi

Could any one teach me, how to design and install a CU?
How to select RCD,MCB(and connection)?

thanks in advance.​

Highway Star deep purple might also do, if your passing the duchie around

Good Track!!

Either track works for me - I've still got both on 'vinyl' (a term my son doesn't understand). But at the controls of an A330 I'd prefer to keep the 'kutchie' passing to a minimum.


... though, if we're still talking about Mr AliRaZoR's CU change, perhaps Smoke on the Water ( ..a fire in the sky) is more appropriate...

is there any book that i can read and learn?
thanks

You mean you can actually read.

I'll help you but i want 500 quid with no certs:6:

Alirazor.

would you go on a plumbers forum asking step by step instructions to fit a new combi boiler? No you wouldn't because its gas and its dangerous
so why come on to a electrical forum and ask step by step for a CU
your out of your depth, leave it to an electrician.
if you do go ahead and do it anyway, and your house catches fire, or god forbid someone gets killed, i hope the £500 or so saving was worth it.

I've just gone on a medical forum asking for a step by step procedure on an heart transplant, I told them I had some white spirit, a very sharp Stanley knife, Hacksaw large and junior, and so good lighting, and got barred I wonder why!!!!

They never let me get round to the pump part, do you guys think that an aquarium pump will be big enough when I need to use it on the bypass stage??

Look fella, what you are asking advice about takes us electricians a long time to learn. There isn't a book on how to do a c/u change step by step, you have to learn every aspect of the electrical installations before you can attempt it. Fare enough its not rocket science but your playing with things that can kill you or others, your not playing with lego! Phone a local spark who can do this for you and keep your home safe.

As you're from an electronic engineering background you can appreciate that changing a CU is akin to developing a PCB with corresponding components. It requires the skills to test and upgrade the earthing and bonding. It also requires the knowledge to select an appropriate type of circuit protection device for each circuit, whilst ensuring compliance with the appropriate British Standards.

Whilst one could describe the physical process of installation, it's the inspection and corresponding testing, that ensures compliance with BS7671, that's more important. This will require the purchase of high cost test equipment and the necessary training to use them correctly.

Whilst I'm certain that you would not have a problem with the electrical theory involved, there is a lot more experience required than just understanding the theory (although it does help a lot).

The advice you're being given, although in jest, is serious.

I do not want to change my home CU or other people CU, i just want to learn something. i have some information about home wiring, MCB selection, but i only asked for the RCD wiring and the way that is connected in CU,...

Sorry I don't believe you. A little knowledge is a dangerous thing, and that's why I hope no one gives you the answer to your question. Why would you want to learn about this subject if you are not going to change a c/u? Why have you already got information about mcb selection? Sorry but I'm out.

Some of these books may help you with certain areas :thumbsup
