6mm or 10mm electrical bonding?
Hi all,
I am due to have a conservatory added and company insist my electric are bonded to 10mm to be in line with new part p building regs. I had a new boiler installed with relevant new timer controls. The electrician then seemed to be happy and he gave me a minor works certificate in addition to British Gas providing the overall certificates. My questions are 1. does bonding require updating and 2. should this have been done in December when the boiler was installed, therefore I could hold them responsible to do the job properly? Would appreciate your wisdom. Many thanks Shirley |

6mm or 10mm electrical bonding?
I'm fitting a new consumer unit and the requiremnet is 16 sq mm for the
primary earth to the supply and 10 sq mm for the secondary bond(s) to gas/water/oil. My place has a PME earthing which has the most stringent requirements, other earthing arrangements may not. Although the size of secondary bonds is specified in the wiring regs, I don't think it specifies which kinds of work require an update. Generally the regs don't apply retrospectively, so if no work is carried out on that part of the system then there is no requirment to update. If building the conservatory requires the secondary bonds are moved, then yes they probably should be updated. |
