If you don?t mind I have a question on the way this question is worded in a way that may be a little different then normal, not how many wires in a 3/4 inch conduit but how many homeruns. The term homeruns can mean the entire grouping for a circuit as one homerun which would mean the answer would be different if it was a situation where you were running an independent neutral with each circuit or if the circuits were sharing neutrals. Exactly what are you trying to do?

sat -And if he had 277V or was loading with inductive loads, the answers will be different.

Could you explain these two? I don't understand why either one would matter.

Hummm ... I'll make a couple of assumptions:It said Electrical Engineer in your profile, think what happens when you put conductors feeding a bank of ballast in a metal conduit.
Hummm ... I'll make a couple of assumptions:
1. By "metalic", you mean "ferrous".
2. The conductors are installed per NEC - all the circuit conductors are in the same raceway.
So, is the answer, "The conductors warm up porportional to the current loading - same as if they were in a non-ferrous conduit?"

This is the part I don't get. You're using some physics I've never heard of before.We derate the conduit to reduce problems from the effect of heating, all conduits are enclosing the conductors, and in metal conduits, we have the additional effect of not just current loading, but also the added effect of induced induction loads, and these loads can, if not derated, reach a temp hot enough to cook an egg. ...
