Evening all, Need some opinions on this one please: TNC-S house, complete new install, all going to plan, nearly finished second fix, customer then arrives with a huge metal lamppost (bought from Frinton-on-sea promenade...) and wants it hooked up in the back garden. What is the general consensus on this - my concern is: in the event of loss is supply neutral, everything connected to MET, including that lamppost, will rise to a voltage, anyone touches it may get a shock? Or, will the fact it's planted in the earth keep any possible voltage down? Am I making something out of nothing here or would this be safer as a TT? Any thoughts welcome.
