I need to run 10/2 the length of my house, which means drilling holes in
about 50 joints and avoiding heating ducts. It would be so much nicer just
to fasten the cable to the bottom of the joists. Can that be done with
10/2MC?
I've never used MC before; anything difficult about it?

I know (or at least I think I know) that it can be done with 8/2 so that
might be worthwhile if 10/2BC isn't okay. Is there such a thing as 8/2
aluminum?

Thanks

You can run 6/2 or 8/3 or larger across the beams. You can run smaller
cables if you install running boards next to them for protection

I don't see why not, absent any prohibition on it in your local codes
(you *are* familiar with your local codes, aren't you? Didn't think so).
I see it all over the place. A little ugly if done in a basement space,
but perfectly OK in a crawlspace.

No. Just remember to be *very* careful stapling it; don't mash the
staples down too hard or you'll likely create a short. I like to drive
the staple in just far enough to make it hard to move the cable under
it. (Don't ask me how I know this.)

You are right about the 8/3, but 334.15(C) specifically refers to NM.
320.15 says that AC cable can run on the bottom of joints, but the section
on MC does not address the issue. I take that mean it is okay. But is it?

FWIW ... Up here in Ontario, wiring only has to run through joists if
the area is going to be finished ... otherwise it can be stapled to the
joists.

While you were posting, I was looking it up, you are correct, my reference
is only to NM, AC need a little more attention to mechanical damage, but MC,
your free to staple it across the beams

I don't know much about the CEC... but I'll bet you're wrong. Anyone familiar
with the CEC care to comment?
