So, I'll start by saying that my knowledge of the regulations surrounding lightning protection systems are limited, it simply isn't work that we as a company carry out as we leave it to the specialists.
During an EICR I find what looks to be an old aerial pole on the roof of the building, looks like a 3m scaffold pole just bolted vertically into the roof structure. Now this has been bonded back to the MET with 10mm bonding cable. It's clearly not an extraneous conductive part and so the bonding needs removing. My question is regarding the code to give it. The chances of it being struck by lighting are slim as there are higher buildings next door with proper lightning protection systems and charge dissipators atop. That said, without experience in lighting protection, is it up to me to make this judgement call and give it a C3 or should I just play it safe and C2 it? My gut tells me the latter may well be the best approach.
