Romex in conduit would probably OK in your Code but in conduit you would
have to derate the conductors as per tables in your electrical code.

It's all about cooling the conductor so it doesn't overheat and give you
fire problems.

Remember not to put extension cords under a rug? Samething applies...heat
buildup

So a #14 wire is good for 20 amperes in free air, 15 amperes in a cable with
other buddies and less in conduit, depending on how many buddies in in bed
with it. Our electrical boxes are all marked in cu in or air space now and I
believe the US is starting that also. Less air space means less wires
allowed and less connectors.

I'm a 1-hole/1-wire kinda guy. If the NEC won't let you put Romex
into a conduit, why stuff wires together at all? Remember that when
you're in a workshop, most of your plugins are high-amp tools. Act
accordingly, eh?
