That makes sense, and its something I never really thought about too much.
Out of curiosity, does that mean it'd be within code to run a 30A 110vac
circuit (with 10g wire & appropriate breaker) with a bunch of 20A outlets
How does GFI protection play into a scenario like that? In my garage,
I've got a GFI outlet as the first in a series on a circuit, protecting
the rest of the outlets on the circuit. Can that GFI outlet handle
protecting a 30A load?
And, at least for me, the garage 220vac outlets are 50A (6g or 8g wire, I
can't remember), and that wire was kinda hard to do anything with a wire
nut... I'll check out the split bolt ones someone mentioned... Sounds like
a good idea.
