Hi all,

Ive just been looking at a CU setup for a friend at his soon to be new house.

Heres the current set-up

CU :

100 Braker switch

32 Amp MCB Ring main (Whole house)
32 Amp MCB Cooker
32 Amp MCB Shower (6mm cable running a 8.5kw shower)
32 Amp MCB (spare)

6 Amp MCB Lights
6 Amp MCB Lights
6 Amp MCB (Spare)


It looks pretty simple, but would like some thaughts on it... Does it sound ok? Is the shower ok on just a 32Amp MCB?


Thanks for your time

You mean there is no RCD for the sockets or the shower? What make of CU is it?

The shower is a heavier load than the MCB and cable were designed for. Is it a replacement of a less powerful shower?

Rather than having spare MCBs fitted that do nothing, it is preferable to have blanking pieces fitted.

One ring main for the whole house is unusually mean these days.

Why do you want to know?

Hi Doesnt seem to be any RCD for sockets or shower. i dont know the make of the CU, it only looked a small one, Single load (single buzzbar) i think you guys would call it....

I want to know because im interested, and it seems a little strange to just have a shower into a 32 Amp MCB and all the ring mains on one 32 Amp MCB...

The two spare MCB`s were labled up as loft, but had nothing connected to them... I guess they were put in place to allow future connections to add sockets and lighting up there in the future.

Hi all,

I would suggest that your friend calls in a professional to have a look. What do you know that your friend doesnt?
