lighting circuit need rcd protection?

[lee sparks]

Hi guys,
Just wanted some advice on this.

I have a CSU at home with RCD in protecting ring main and boiler immersion socket.

What i want to do is change the pull cord in my bathroom, but that circuit is not protected by RCD, just a MCB. (BS3871)

If i change the pull cord, does that lighting circuit have to be then RCD protected?

(its a grey area to me because im changing like for like in a special location, not installing a new circuit etc)

Just wanted to know how i stand on this>?

Im guessing if the answer is, then yes, you do need to protect that circuit with RCD protection, then i could either put a new rcd 1 way board in just protecting this circuit, or try and retrofit a RCBO in the board?

I thought if just putting in a new B6 MCB BS3871 on the rcd side, there is room! but the busbar has been cut and cant seem to find a re-placement busbar etc.

Thanks Guys!

Lee.

I would say not as it is a maintenance job you are doing, you are not modifying the circuit in anyway.

I would also say you don't need to but it's only making the system safer by moving it to rcd side so that's what I would do.

well...before doing any of this malarkey...i would be checking for shared neutrals...

SELV may be the better way if required...
