Not bad, why?

How on earth do the 1000s of non domestic electricians survive pulling fuses almost every day of their working lives?

Because.... (and I'm guessing at what Tony was eluding to).....what's the maximum PFC you'd expect off a 230V domestic line? Do the maths in reverse and tell us what the Ze would be in order to get 16,000 amps flowing at 230V.

Or even, to give it some real-world clarity, at 245V

Not really, fill out the permit to work, what we need to isolate etc..then go off and do it!

Ze irrelevant, it may be a TT system, remember I said 16Ka+ .You do the maths?
