Surely if confined on a coil then lower current handling?

8 ohms


That 700 circular mils per amp is for transformer/coil calculations.
6.125 amps * 8 ohms = 49 volts * 6.125 =300.125 watts. This would
require a 14 AWG wire for 700 circular mils per amp. which is ten time0
the diameter you quoted. It is 63 mils, or about 15 turns per inch.


It is 90 turns in 15 mm , 2 layers, 1 over the other, so 180 turns

15 millimeters = 0.590551181 inches

1/.59055 * 90 = 152.400 turns per inch.

That would be AWG 34 (143 TPI) or 35 (158 TPI), or British SWG 38 or
39. I don't see how it could handle 300 watts at 8 ohms.
