New Shower Circuit

[jimboGTI]

Evening all,

Ive just finished a small job for a plumber which included me replacing a 6mm T+E cable and 40amp MCB with a 10mm T+E and 50amp MCB with RCD protection. The question i have is this, This would require a EIC as its a new circuit and not a "like for like" replacement but on the certificate do i put all circuits on and test these or just notify what circuits are installed and just put my test results on for the new shower circuit?

any help would be greatly welcomed!

Jim

I think in this situation you need to apply a mixture of common sense and independant thought.

I'll give you a hint with this: you need to carry out inspection and testing as part of the comissioning procedure for the work you have carried out.

Don't think the answer could be any more obvious than that really

 

[Richard Burns]

I would say this was a new circuit, since it is only one circuit you can just provide the test results for the circuit you modified on the EIC, I would tend to list the other circuits names and put 'not changed' by them, but that is not necessary.
The only other bit would be to have made sure the earthing and bonding were adequate and upgrade if necessary.
Because you have installed a new circuit and because you have made an alteration to a circuit in the zones of a bathroom then it is notifiable to building control through your scheme.

Only the circuit you have added goes on your sheet. Surprised the shower stipulates a 50A MCB.

Come on lads, these people should be encouraged to use their brains once in a while to work out answers to questions like this.

I am all for the forum being a place to ask questions about something you haven't come across before or need a bit of clarification on where its not your normal part of the industry or a situation which is new to you but other people here may have experience of. But to be asking a question that almost answers itself and then getting the answer on a plate just encourages lazyness.

The worst that could happen here from not giving a straight answer is he goes off and tests more circuits than he needed to!

I have a car outside my house i scrap it and buy a new one so have i made an alteration to the car that is now outside my house or is it in fact a new car altogether.... hope that clears it up!

 

[davethsparky]

Its these ridiculous 10.5KW at 240volt showers that require the 50A supplies.

 

[Edd]

Hope you checked page 340 of the BGB, bet that 10mm looks lovely clipped direct...

So, did you install an RCBO?
As already pointed out, 10mm should not be used with a 50A OCPD unless it's clipped direct. That was why I questioned it.

 

[dave274]

buried in plaster is classed as ref c so maybe its not clipped direct.

 

[Geoffsd]

10.5 @ 240 is 43.75A (equates to 9.64 @ 230 and 42A) so

perhaps the cable didn't need replacing (if method C)

I realise not all manufacturers make 45A MCBs.

 

[telectrix]

but all shower manufacturers make showers under 9kWatts. 10.5kWatts is ludicrous. the whole point of a shower is to direct hottish water onto your body sufficient to get the grime off with the aid of some soap, and get out as quickly as possible so you can sit down with a pint.

 

[Toonlad]

so when i installed my shower i started to drink more, now i know why ..lol

I have a car outside my house i scrap it and buy a new one so have i made an alteration to the car that is now outside my house or is it in fact a new car altogether.... hope that clears it up!

Ah but, if the car is the same make and model as the old one is that not a like for like replacement?

 

[Spoon]

10.5kWatts is ludicrous.

Thats nothing... I want one of these.. 27kW, 3ph, 380-400V
