Shower supply, ever needed additional earth cable.

[Spoon]

This may be one for the older members on here.
Got chatting with a mate about a general supplies to showers.
At the moment you just supply the correct size cable, (usually 10mm for a new circuit) to a shower.
Was there ever a requirement/regulation to add an additional earth cable along with the power cable? Thinking old regs...

In the distant past I believe there was a need to add an separate earth cable, don't know the reg number or even if there was one,

Sounds like the 16th to me when equipotential bonding went a bit mental.

Supplementary bonding

Neither am I. I'm just curious about it.
It sounds like it may have been a thing when the domestic people had to earth everything metal in the house...

Supplementary bonding

I think so... But was it a reg or best practice thing.

It came under special locations

So was @essex correct in that in that it may have been in the 16th?

 

[chris gray]

Yes,
Maybe on site guide if memory serves me

Only time I have ever seen additional green/yellow cables in shower circuits it has been supplementary bonding.

Still required if certain conditions are not met ?
