supplementary bonding after new consumer unit fitted

Katron · Posted: Tue Aug 05, 2008 4:29 pm

Been to look at a board change and it needs supplementary bonding in bathroom (and is no airing cupboard near by), the problem is the bathroom has been recently decorated, could I do the board change (as the installation would be in a safer condition than when I found it) and record it on the cert or is it regs that is has to be done?

Obviously I want to do it but customer doesn't want me to go ahead.

Many thanks Katron

'cmon - take a deep breath, hold it for 30s while you reflect on the fact that you actually do know the answer to your question, and then exhale.

i was at college today doing my 17th edition and the tutor was saying if you protect all the circuits in your bathroom by a RCD you dont need supplementary bonding

Oh poo - yes, of course you can.

Main bonding has to be in place for that solution.

BAS could you explain this for me please.

REG 411.3.1.2
regarding a part to be considered for supp bonding to be omitted.

bonding to 1 water
gas
other installation pipework
central heating and air con
exposed metallic structual parts

I don't fully understand the central heating.......if you have a rad in there do you need supp bonding, or if its gas central heating will that be ok because tme main gas is earthed?

Sorry for being dim i would like to get my head round it...

Many apologies
