Hi there,
Just a quick question. Does a main protective bonding conductor require UV protection when run outside?
I am under the impression that this is not a requirement as such, but if possible, it should be considered. Especially if installing a smaller sized conductor.
I am running a main protective bonding conductor to some structural steelwork some 180m away from the service intake. 120mm supply, so 35mm bonding conductor (TN-C-S earthing arrangement).
As it's a large CSA, mechanical protection and corrosion protection is not a problem; and even if UV rays did break the insulation down, it wouldn't be a problem.
I will run this in ducting anyway, but I just thought I'd ask the question as I we often see bonding conductors run outside without any protection.
Thanks again guys for your valuable time and knowledge.
