I have been pondering this idea, but looking for validation. I want
to wire up a 40 to 50 amp circuit 220V for a welder.
Due to the high price of copper and stiffness of 6-8 Awg wires. Can
I save time and money by installing a electrical box /w receptable
just above the (in-wall) breaker panel, in the same cavity, without
going through the header? I am thinking of using an old work box,
the kind that clamps on drywall.
Is there anything in the NEC code that states you cannot have the
recepticle too close to the breaker, for example 2 feet of wire?
If not, what about the same situation but using a metal box mounted to
a stud on the drywall, with the wire coming in from behind the box
(part of dry wall cut out). Since the higher ampere plugs are
stiffer, I am thinking a old work box might not take the abuse well.
Wires will be clamped inside the box.
