copper pipe earthing

[37skippy]

Hi new to the forum,but it looks very help full,


I need to earth some 15mm copper pipes in a down stairs bathroom which are fed from copper to plastic to copper,(if that makes sense)i have read to do it in 4mm earth cable but i do not have any

I do have plenty of 6 & 10mm is there a reason the 6mm cannot be used

Any help would be good


Cheers

You can use 6mm. Its overkill but wont hurt.

By the way, supplementary bonding is only required in rooms with a shower or bath. Though I appreciate a "downstairs bathroom" may indeed have both, for most its just a bog and a basin. Supp bonds are applied to all incoming metal pipes and electrical circuit protective conductors.

Thanks for your help

The down stairs bathroom will only contain a sink and bog and washing machine and tumble drier.

The room is fed by copper in the ceiling then it ends and plastic takes over through all the timber frame work then as the pipe work comes out the wall to feed which ever bog,sink etc i have joined it back to copper to come out through the wall to make it more rigid.

I thought you had to join the copper in the ceiling to the copper coming out the walls because the plastic breaks the earth


Yes or no

You dont need to bond anything. There wont be any naked wet bodies in there (normally), since there is no bath or shower.


The only bond you might have is main equipotential bonds, which are applied to incoming metallic services only where they enter the house - so water, gas, oil - and joins them to the main earth terminal near the electric meter and fuse box.

The OP can live in hope!!
