Re: 4 Wire sub-panel...HELP
.2234 Ohms for the #8,
.0126 Ohms for the #4,
Total ground fault path resistance of .236 Ohms.
Assuming a voltage of 120, I then used Ohms law to determine current. I=120/.236=508 Amps.
I don't know what numbers I used last time!!!
I used the resistance values of a #4 and a #8, each at 300' in length to come up with the total resistance of the circuit.
