My partner and I bought our first house a week ago. We don't have much DIY experience but we are determined to learn and do as much work as we can to save cost.

The house is a 3bed an ex-council house built in 1959 and needs a complete refurbishment.

The existing CU is not too old (pvc wires) but we have to add sockets, electric shower...and we prefer to get it upgraded. Please see photos.

I have had an electrician having a look a few hours ago. He said he can move the CU 180 degrees facing the hall with the length of the existing cables. He quoted me ÂŁ250 for moving the CU, including new CU.

He said he could install the following CU:
http://www.screwfix.com/p/british-g...dual-rcd-consumer-unit/2920g?_requestid=39295

If I replace it I would like to get a good quality one with space for more modules and individual ring per floor for the lights and sockets, 2 sockets outside, an electric shower, induction cooker, oven...

I am thinking something Like:
RCD 1
32A Upstairs Ring Main
6A Upstairs lights
6A Smoke Detector
16A????? Immersion heater - in case the gas boiler fails

RCD 2
32A Kitchen Ring Main
32A Downstairs Ring Main
6A Downstairs Lights
45A Cooker

Do you think I could reuse the RCBOs from my current CU for the new one :
RCBO 1
Electric Shower (9-10kw)

RCBO 2
Outside sockets or kitchen sockets


My questions are:

1. Could you recommend a better Consumer Unit?

2. Would it be to much work and too expensive to split the existing ring socket and lights per floor? Or should just leave as it is?

3. What do you think about using the RCBO for shower and outside or kitchen socket?

4. Could you please arrange the two RCDs in a better way?

5. Do you think the MCD specs are OK (amps)?

6. What do you think about this job for ÂŁ250?

Thank you very much. We are quite stressed wih the refurbishment and your help would be much appreciated.

whats wrong with that board? its got the stab bus bar so just buy a selection of crabtree rcbo's to stick in it? better to do that if your on a budget than buying some BG piece of garbage

Suffolkspark is right, you have an 11 way starbreaker consumer unit, you just need Crabtree Starbreaker RCBOS for all the circuits. Bin the old style 2 module RCBOS to maximise your capacity at the ccu.
I would be a bit wary if your Pole didn't point that out straight away. :pileofpoop::speaknoevil:

Taking all of the guts out and replacing them puts it into dubious territory on the non-combustible CU front. Especially considering that, as far as I know, the whole lid is plastic not just the window.

What guts?

And wasn't you waffling on about no such thing as non combustible the other day? :tearsofjoy::tearsofjoy:

Honestly the people that post on this forum, you wonder it they ever worked in the real world ! :flushed:
 
Old CU's and new RCBO's are some times compatible, as long as you seek manufacturer guidance first. However, I fitted two Hager RCBO's in one of their older CU's, and there wasn't a lot of room for the wiring termination.

Some manufacturers offer RCBO populated CU's, which are cheaper to purchase than individual devices, and the CU has been designed for RCBO's.
 
Actually given that RCBOs are a type of RCD it most certainly does have RCDs. It doesn't have any RCCBs however.

Boys ......... the vast majority of Joe Public don't understand the differences ........ so I stand by my statement (and I don't think the later versions of the RCBO will fit that board ).

The OP needs a new CU............. end of.
