Default 12 amp wire size

According to Meat Plow :

I used to work with Baldor repulsion/induction motors in the oilfield.
There were all 240v, 15 hp. If memory serves, on the well upstroke they
drew around 30 amps and otherwise around 18.


240V at 30A is 7200W, which means that during the upstroke those
motors were delivering somewhere around 6-8 HP. Conservative
motor selection, given that weather/rig conditions etc could cause
the motor to need more.

It would have been interesting to compare that with the motor
plate ratings, or know what size the fuses/breakers were.
