Earth bonding in a bathroom

[EricP]

My pipework is metal and is bonded at the sink in the kitchen but not upstairs in the bathroom. Plastic bath, no electrical outputs in the bathroom except lights (Pull cord) and a shaver socket (Usual BS type)

Having the way open to put cable in, I wish to take a cable upstairs and bond the bathroom pipes.

What size of cable would be recommended?

Nothing was apparent in the number of posts I have downloaded, or I wouldn't have bothered to ask.

Following your generous pointer, I will set the browser up to load the rest of the stuff in and begin searching.

Thanks.

You'll find lots if you search in Google Groups. Also have a look at

you don't have to bring in an earth from outside (unless the rising water main in in the bathroom in question). Supplementary bonding in a bathroom is about connecting certain accessible exposed metalwork together, so that dangerous 'touch voltages' can't arise.

The size of wire you're most likely to need is 4mm^2.

Thanks Andy. :))
