They are running a pair of toroidal transformers to get the capacity and
feeding each one off a separate 220 circuit so you would not need a
monster feeder to the shack.

#10 copper to one or more an outlets. #10 can be fused at 30A in North
America. #8 and #6 copper are not all that uncommon, and often run to
sub-panels. Doing the arithmetic, 30A is 7,200 W at 240V. Last I looked,
the FCC Rules limit my output power to 1,500W. Dunno about other
countries. How many of these amps would be transmitting simultaneously?
Is this for a multi-multi contesting station?
Actually just as a matter of minor interest, I have run #6 copper to a
single 60 amp outlet to power a Henry 8K. No big deal. It would be
interesting to compare the 8K (3CX3000A7) against the OM4000HF with the pair
of FU-728F's, or possibly 4CX1500's? Back in the day, the 4CX1500 was a
drop in replacement for the Collins 30S-1, which then brings up the Alpha
8410. Any experts care to make comparison comments? I'm just an interested
listener. Or lurker. Both terms apply.
And if I may, I've always had tremendous respect for FCC rules and
regulations, but that said, comparing a gent who has Rhombics facing each
cardinal direction fed with 1500 watts, compared to some poor soul with a
dipole running his home brew pair of 4-1000's or even a 3CX10000..... No,
it is not legal... but when trying to bust the pile-up, I get it. Just
sayin.
