regs regarding earth bonding

[bob the plumber]

what are the requirements when a boiler is installed, i keep being told different things. I know bonding is required on the incoming mains for gas and water however is it required anywhere else on the pipe work, e.g under the boiler? i hear differnet things, one sparky may say you dont require it if your rcd protected then another sparky may say otherwise

thanks

bob

you will not really get a striaght forward answer to this. electrical regs state that all extrenuous conductive parts are earthed. so gas and water at entry to house (withing 600mm of supply) hot water and heating flow and return. that is standard for an RCD or no RCD protected fuse board. then you have supplementary bonding, which is found in 'at risk' areas such as bathrooms and kitchens. this is not required (although still a good idea) if all the electrics in that room are protected by RCD's. The earthing at the boiler where you earth each pipe in a pritty loop effect from clamp to clamp, would be supplementary bonding if all the main earthing is correctly done. I have taken the 10mm eathing and looped it as described, where the main earthing was connected near by. If the address is fully protected by RCD,s as per 17th edition wiring regs then there is no need to do the supplementary bonding at the boiler.told you, clear as mud!

I just read up on this and what I read as Eddie described.
( Can't ask Mr TP because he is out - isn't he always! This time an emergency for friends.)

Except - I didn't think Kitchens were an at risk area according to the rules of Electricians even though it is according to building regs. I could be wrong. And this makes no difference to your bonding question. You could have asked on the electricians forum.

You don't need to concern yourself with what needs bonding or how it is done if you are not qualified. Leave it to those who do know.
Your only obligation is to inform the responsible person (in writing) to get it (as in the gas pipe, no more than that) checked by a suitalbly qualified person. You can buy properly worded cards or make up your own.

ill be qualified in 3 weeks all going well tamz so it would be handy to know if you know what i mean 🙂 i actually have my part p defined scope ticket but dont tend to get involved, we most of the time get a sparky in to come in and take care of it but it was just something i wanted to know 🙂 thanks
