17th edition CU

[sijaysee]

Fitting a new board in a bungalow

one ring circuit
one lighting "
one cooker "
one immersion "
two panel heaters "

Best way to connect?

Split with 2 RCD's?

Cheers

Depends how they are installed.
My opinion is it is better to keep the lights on their own, possibly via RCBOs. Maybe worth looking at splitting the lighting circuit into two also.

The rest you can do as you like, probably better between 2 RCCBs

Also please note that this work will be notifiable to your LABC under part P of the building regs.

splitting the lighting circuit is not really viable without major work.
maybe just keep the lights, cooker and panel heaters on one rcd
and the sockets, other panel heaters and immersion on the other

 

[Adam_151]

Conventional split, RCBOs for lighting and socket outlets, and everything else on RCD side?

 

[sijaysee]

yea i guess. i suppose the cost wont be too different
when you lose the one rcd and replace it with two rcbo's

 

[securespark]

smokes should really be on their own , so that another circuit tripping an RCD bank will not knock them off.

CU with DP main switch then rcbo the rest.
Can be done for the princely sum for materials of £51.44 + vat, granted it is using CPN kit .

CPN / CHiNT isn't that bad for a budget CU.

TBH for 5 ccts I'd go with RCBO's as the split RCD boards are very large in comparison.

Comms

That link gave RCBO's @ £30.99 a go I'm getting MK ones for £21 at moment.

Double or single pole?

Yes I picked some Wylex rcbos up thismorning for £24.99

 

[Katron]

where are you getting the rcbos from? wylex and the mk?

cheers katron

 

[sijaysee]

comms, are these CPN boards any good? where can you get them?
how can they be so cheap? works out less than a tenner
for each rcbo plus the board and main switch

 

[RF Lighting]

cheap

 

[sijaysee]

ok see your point!
so its likely to be over a ton to use rcbo's
