Supp bonding to a bath

[Dave 85]

Hi lads
Could someone please remind me of the requirements for supp bonding in a bathroom which has all circuits RCD protected, not got a regs book to hand.
Many Thanks

Assuming the RCD has an operating current of 30mA and all circuits in the bathroom are protected there is no requirement for any supplementary bonding.

Also assume that your main equipotential bonding is up to scratch of course.

If all main bonding is in place and complies and the circuit is protected by a 30ma rcd supplementary bonding is not required.^^ 3 to slow again.

Cant see why as long as your main bonds are in place and check out ok.

Thanks guys
Thats what I thought.
Had a client text me and say another electrician has complained I didn't bond her bath.

Ha
Just spoke to her and explained
She said "oh that makes sense, the guy who pointed it out wasn't an electrician anyway"

You just got to ask them for a reg number , That usually kills the conversation lol.

It is not the case that if RCD protection is in place you can ignore supplementary bonding. All extraneous conductive parts within the location must be effectively connected to main bonding in accordance with 411.3.1.2....this generally means a continuity reading <1667 ohms.
701.415.2

It's highly unlikely that a bath will be an ECP....the pipes supplying it probably will be,so it is the pipes which may require bonding,not the bath.

You are quite right I forgot to add the three requirements of 701.415.2 . This was a topic in a recent post that I included the reg numbers.

So an electrician who isn't an electrician says you're wrong, well that makes perfect sense doesn't it.

Plumber ...got to be interfering Gits

Aye they are the ones who play hell if the gas aint bonded at the meter.
