Earth bonding - Plastic pipes / Metal radiator

[jazz-uk]

Hi

Apologies if this comes up a lot, but just wanted to confirm something.

Having a new bathroom fitted complete with new plumbing and electrics. I have a metal towel rad which is connected to the central heating system using plastic pipes.

Does the electrician need to do supplementary earth bonding, because its electric. The IEE pdf suggests it would be more dangerous if it was bonded, and suggests it doesn't need it !

Thanks

If it's bonded then you're providing a fault path that wouldn't exist without it since there would be no effective path off it.

If the pipes were copper then bonding would be required.

Sorry, but whats a fault path and an effective path ?

Does the towel radiator have an electrical connection? If so then the CPC of the circuit supplying it should be included in the supplementary bonding.

Nah, its a standard towel rad plumbed in via plastic pipes, and screwed into a stud wall. No electrcial connections whatsover

Does he need to bond it because its metal ?

it doesn't bring an earth poential into the bathroom ( plastic pipes insulate it.. ).
