Locations containg a bath or shower - Additional protection

Circuits still need supplementary bonding together.
Obviously not the pipework if plastic
There's a good detailed drawing in guidance note 8 if you have a copy?

And if the metal pipework is not extraneous?

Edit; thanks I'll have a gander.

When we supplementary bond in the bathroom without rcd protection we bond all associated circuits in the location and any extraneous parts like pipes.
Nothing's different with non extraneous pipework apart from the pipes , which won't require supplementary bonding.
Circuits don't change tho do they?

Hi MW - for what it's worth, I would probably add the rcbo to the job and notify it.

Suppose I'm just interested in the logic of it, bearing in mind I can replace luminaires like for like.

Because new work like alterations need to meet the requirements of bs7671

But if there's no extraneous conductive parts, there's no reason to supplementary bond them. In this case I only have one circuit. So if I use this 2nd light circuit (without RCBO) you saying I have to local supplementary bond both these circuits?

I'm not questioning new work, i.e. adding a new luminaire or new shaver socket. Just replacing light with shaver socket, which I guess is not like for like?

Thanks have the page open in front of me also.

Actually looking at Fig 8.5?

Thought I would just report back. Elecsa Technical agreed with you chaps.

My suggestion of replacing luminaire with shaver socket on existing circuit, would no longer be regarded as maintenance. Therefore the alteration/addition would need to comply with current regulations.

Rcbo it pal.

Gonna, and the rest of the upstairs lighting!
