it actually is a requirement in canada. Any gen panel you buy here has a switched neutral.

note the three pole mains.

I've seen lots of people get a whack off the neutral even if it not open. All you have to do is provide a better path to ground. The reasoning behind it is that current takes the path of least resistance. The wire going to the tranformer is larger than the wire comming from your gen so some of the current will backfeed the neutral of the transformer.

Exposed Romex would not pass in my jurisdiction. Why not sleeve it in 3/4 EMT or PVC. That would physically protect it and make a better looking installation.

Looks mean absolutely nothing in this situation, this is a garage ceiling.

I don't agree with that. A run of conduit across the ceiling would look way better than the squiggly, possibly droopy Romex. How many staples/straps would you have use to get a nice tight run? Versus a few one-hole straps holding up the conduit.

Regardless, in my jurisdiction the exposed Romex would be subject to physical damage, thus being a code violation. You could use MC across the ceiling and be compliant with the code.

That's fine, but it is my opinion that looks mean absolutely nothing on my garage ceiling. You only have reign over your own garage, not mine

Every other stud (32") should be MORE than enough to keep 8-3 straight, it's already pretty stiff to begin with.

But tightness doesn't matter much, not in this case at least

As I said earlier, if there is any issue whatsoever, I'll throw a piece of crown molding over it.

What about where the romex comes out of the wall and turns into the pipe that you propose? Wouldn't that bit be subject to physical damage too? Or are you suggesting I put a 90 with a kick on it on each end and bring the pipe into the wall? Why not just pipe it the whole way then? Or I could just strap the Romex up to the ceiling and have a legal, safe installation

As some other posters said (some downstream) in addition to the aesthetics, it's a question (perhaps the key question) of whether it is a legal installation in your jurisdiction and would pass inspection!!

My state follows the NEC with only a few amendments, none of which deal with heightened romex protection.

the determining factor of whether Romex may or may not be run exposed, or the use of banned altogether is not determined by height. In NYC, for example, the use of Romex in wiring is prohibited, except in temporary wiring on construction sites. In most jurisdictions, however, it is permitted in residential structures, but not in public (access) buildings.!

When I said "heightened romex protection" I also meant "strengthened romex protection". I wasn't talking about the height of the romex.

However, in post #1 you DO speak of the (relative) geographic position of the cable. ....It would run at the (7-foot high) ceiling. So I understood that you're taking the height of the cable (being out of the way) as an additional form of protection. Therefore, it should pass inspection.!
