Whatever you do, make sure all the mics and guitars have got their own
personal in-line safety isolators.

Too many dead musicians in the past due to poor electrics - of course an
area part pee doesn't cover at all.

Often down to faulty instruments or PA systems. The common way these days
is to PAT them all before use. Older method was to use a mains isolation
transformer on each and every instrument. But this was in the days of
valve amps where some didn't include their own internal isolating
transformers. Most solid state gear will, as it runs off a lower voltage
'HT' rail.

We often have a 100 KVA genny out for filming where mains isn't
available. And I don't *think* they sink an earth spike. They run a 45 amp
(or two) circuit to a sort of rugged CU, and 15 amp circuits from that.
I'm not actually sure what sort of breakers are in that CU, though.
I'll ask on Monday.
