Hi. Thinking of setting up on my own and planning to join one of the "clubs". The job i have chosen for the assesment is a consumer unit change. The earthing arrangement is TNC-S and the Equipotential bonding is present to gas and water using 6mm cable. My question is this, do i have to upgrade the bonding to 10mm or do i put a comment on the EIC. I have looked in the regs book but can not find anything on it.
Table 52.3, 54.1, 54.7 and 54.8 all refer to cross sectional area. Also it is Book 3 which explains how to do inspecting and testing and also some reference is found in the Guide to 16th Edition. I don't think 17th Guide is out yet. I am not a member of any of these "Clubs" so I don't know what they look for.
I have been a member of ECA for many years but have my 'part-p' provided by NAPIT. In fact this is my last year with ECA due to low returns for high fees!
In answer to your ? both say catagorically that if changing Con. unit then main and equipotential must both be to latest standards ie 16mm2 main and 10mm2 for services bonding, they say that if not done when board changing when will it get done?
Good luck with whichever provider you choose, assessment seems to vary with local assessor, my ECA one was a pr@t but NAPIT guy very helpful, but wanted to choose job & was VERY thorough but fair,
