reg number

[betty swollocks]

does anyone know of a reg regarding the non supplementary bonding of pipework supplying a combi boiler (which is housed in a connected garage) water and gas bonded in 10mm at services, (gas in garage water under sink)

thanks in advance

I thought you meant car reg numbers like OBO 110X for example... Not 100% but didnt think this was necessary under 17th?

It isn`t necessary mate - ergo there is no reg. for it!

I have'nt got the regs in front of me but think it might be 415.2.2

i know its not required in the 17th however recently i rewired a house and the old guy is being a pain insisting it should have been done, ex british rail engineer, telling him this doesnt sink in and i thought a reg from the red book would make him crawl back under his rolling stock.....

415.2, 544.2 701.415.2 are a few that i have found regarding supp bonding. I would say if you satisfy all stated in part 7 then you dont need it. The only thing is you wont be able to tell if the heating/hw pipes are bonded to earth as they are theoretically cross bonded by the boiler jig where the pipes go in. When the boiler is pulled out they might not be earthed and this is when it will be needed. 544.2.5 says that any appliance fed with a short length of flex, the cpc is enough earthing. Hope this helps mate.

Give him the number of your schemes help line and tell him to ring it.

It isn't needed and hasn't been for over 25 years. It goes back to the days when it could not be guarenteed that the pipes were electrically continuous at the boiler. However the BSs boilers are designed to have required the pipes to be electrically continuous for 25 years or more now, thus doing away with the need for 'cross bonding'. And anyway, it used to be a gas reg, not an electrical reg I believe.

Alternatively, do it and charge him 100 quid.
