I want to add a circuit to a 208 panel, but there are no holes and I really
don't want to go at it with a hole saw.

There is a circuit consisting of one outlet connected to the box by 1/2"
conduit. If multiwire circuits are allowed on 208v, I could put the
outlet on one leg of the multiwire circuit and put my new circuit on the
other. That way I can just put my new MC cable to the bottom of the outlet
box, which does have a hole.

Seems to me that it should be pretty much the same as 240v, except that
some current will always be returning over the neutral; but there is no
harm to that. But maybe I am overlooking something (which, given my
knowledge of 208v, is not unlikely)

If I can't use a multiwire circuit, can I simply attach the MC cable to
the bottom of the outlet box and run it up through the conduit to the
panel box? I think 1/2" will take 6 #12 wires.

Thanks.


What you're proposing is fine. Bring your cable into the outlet box, splice
the two neutral wires together with a pigtail to the outlet, as the neutrals
of a multiwire circuit cannot be dependent upon a device, and run your new
hot leg for the new circuit to a circuit breaker adjacent to the one feeding
the outlet circuit
