Must 10/2MC run through joists?
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 "Toller" wrote in message ...

Toller spake thus:

Can that be done with 10/2MC? 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. I've never used MC before; anything difficult about it? 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.

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? "RBM" rbm2(remove wrote in message ...

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 "Toller" wrote in message ...
