Re: NST and GFI ?
Hi Reinhard,
I don't know what breaker type it was but it was a 48A
circuit
and they were only running 2.4kVA at 240V = 10A, even accounting for the
dodgy load (no offence to your coil there Brian :-) I don't think the
current was popping the breaker.
Your report of the compressor tripping a normal breaker is a bit odd as I've
run a 3kW spary compressor from the normal breaker in my garage no problem?
Is yours particularly large, or maybe just not pfc-ed?
Regards
Nick Field
