Dear All
Im quoting on changing a fuse board and the earth bonding to the gas is 6mm. TNCS system 100A main fuse at cutout (sealed so not confirmed)
The flat has concrete ceilings and floors and the bonding cable is deep in the structure of the building. No obvious route to run in a 10mm. I rang the NICEIC for a bit of advice, they said
" Why are you looking to replace the cable"
I said I thought all bonding had to be 10mm
He said that his guess is the flat was wired under 15th edition regs and at the time 6mm was acceptable.If a bonding cable is in place and shows no signs of heat damage it was perfectly acceptable to leave it in with a note on the cert.
Still not convinced I spoke to another spark I know and, confused he rang the NICEIC, same question different answer.
" No it needs replacing with a 10mm no matter what"
How can I get 2 different answers from them and which is right ?
Opinions most welcome
regards
