Supplementry Bonding

[New2Game]

If a customer dosn't have supplementary bonding in bathroom, and has a tiled bathroom with laminate flooring so dosn't want walls or floor disturbing is it still ok to change CU to add RCD to S/Os n Shower?

 

[Spark123]

Nope, it is part of a fundamental requirement of the IEE regs that before any alterations or additions are carried that the earthing and bonding arrangements are adequate. Maybe wait a few months as the supplementary bonding in bathrooms may be dropped in the 17th edition in favour of RCD protection of all circuits in the bathroom.

Sp its a case of rip up the laminate or some tiles of the wall?

 

[Spark123]

It doesn't have to be done in the location, is there an airing cupboard adjacent or something?

 

[davy_owen_88]

Are there no accessible pipes? Can't you do the bonding in a nearby airing cupboard etc?

EDIT: Too slow.

 

[New2Game]

No airing cupboard, pipes come straight up wall from bath feed, its a combi boiler you see

 

[New2Game]

Can a normal battern light fitting be installed in a bathroom in zone3?

 

[Spark123]

I wouldn't. The only reg is the one on it being all equipment being suitable for its environment, taking into account humidity etc is a batten lampholder suitable?

 

[New2Game]

Wot would u use then, is it a case of buying a purpose made fitting?

 

[Spark123]

Me, I'd be tempted to use either one of those globe enclosed ones or bathroom downlighters. (remember I'm a factory spark!!)

 

[New2Game]

So you'd defo say against regs to have battern then???

 

[Spark123]

Lets just say I wouldn't put a batten lampholder up in a bathroom! That is my opinion, other people may have differing opinions on the matter.

Personally, I would only consider a batten if it was outside the zones, and even then I would much rather install some sort of IP rated fitting.

 

[sanj.varah]

a bit of an aside but does the 17th edition stipulate that all circuits including the lighting circuit be RCD protected?

i thought that would mean either running an FCU from the bathroom circuit to control the lights or a separate radial from the RCD end of the CU to the lights which seems like a major ballache.

theres a lot of speculation/rumours/conjecture regarding the 17th edition but as it isn't in force yet we will have to wait and see,
