A student at a recent seminar I held came at me with this question that was on the Experior Master exam he had taken just a couple weeks ago.
Anyone want to give it a shot?
What size PVC sch 40 conduit would be required for two 3-phase circuits sharing a common equipment grounding conductor. Load 1 is at 30-amp, Load 2 is a at 50-amps. The ambient temperature is 124 degrees F. and both loads are continuous.
