Turns out I'm one circuit short in my shop subpanel. I need another
240V outlet, but have no free slots, and can't solve my dilemma with
half-heights (it's only an 8 slot sub). I also cannot fish to the
location I want (without massive renovation) from another 240V
receptacle (they're currently all dedicated circuits). My plan was to
pull the sub and install a bigger sub to run the new circuit (it's
easy to fish from the existing sub to the receptacle location).
However, that involves a fair amount of work as well, but I'll do that
if that's what the NEC spells out.
So the question is, in lieu of the bigger subpanel, can I simply put
both circuits (existing + new) into the circuit breaker or can I make
up a pigtail in the subpanel box so only one wire goes into the
breaker? I'm guessing (been too long to remember) the former is a
no-no (multiple wires under single screw) and have no clue about the
Any of you NEC experts have the handy answer?
