It just occurred to me ... at 440 VAC ONE (1) kw is only about
amps ... 14 AWG (4,107 circular mils) has a series resistance of
ohms for the 1,000 foot round trip. That is about a 32 watt loss (~3%)
for the wiring loss ... not bad for almost a 1/4 mile. The series
resistance for 12 AWG is ohms (about 20 watts loss) and 10 AWG is
ohms (about 13 watts loss) per 1,000 feet round trip. These
figures are for copper from Mark's Mechanical Engineers' Handbook, 6th
Edition.

Any way you cut it ... that still a pretty serious hunk of wire! That
is about 40 pounds for 1000 feet of 3 copper wires of 14 AWG ... total
weight is dependent on insulation selected. 10 AWG would be about 2X
the weight.

Hope this helps.
