>If you are counting on coiling the wires of the circuit together to cancel inductances, better include the ground.
Uh, oh! That had better not be.
Okay, Mr. Moderator, here's the scenario.
My cable make 237 full tight loops before it gets a motor. The motor shorts out to the housing which is hooked via GRC which thanks to my careful workmanship provides a low impedance path back to the panel comparable to the grounding wire.
Now is the fault current going to be stymied by those 237 loops?
