I bet it's less than a dozen, out of the millions of miles of overhead wire in the US alone. These are rare occurrences, to be sure, but so are many electrical hazards. That, then, could negate the protection of the GFCI on the cable's other circuit. In the scenario you proposed, it's possible that the ground could be interrupted and the non-GFCI circuit could be shorted to the portion of the ground that is no longer connected to the panel. That's much less likely to happen with wire in conduit. A single ground is allowed in multiple same-phase circuits in conduit, but the concern of the time was that Romex is much easier to damage and affect all the circuits, and much more frequently, with a single overdriven staple. Certification enlisting wasn't complete then for it carrying dual circuits, because there was concern they would have to include two grounds, it both circuits were on the same leg. I'm just reiterating what I was told at a trade conference about 18 years ago from a Southwire rep. If you know an electrician and can work with them then clear things up with them first. It's hard to take responsibility for a job without doing the whole job because if something goes wrong down the line, there is going to be a lot of finger pointing. Also, keep in mind that a lot of electricians would not even touch a project that a homeowner (or another electrician for that) matter started. I have never run into 12-2-2 wire out in the wild and it's just one of those things that people talk about when they one to one up each other during lunch like "Yeah man did you know they have 12-2-2?" and the other guy says "What?! That's crazy, but did YOU know they have this crazy Romex they call NM-B Duo that has 0-10V wire right next to it?" Of course now that I say this, I'm going to get someone who's going to reply to me that they only use 12-2-2 and it saves them a bunch of time.Īnyway, you have to be sure you know what you're doing here so at a minimum get a book on home wiring where it'll have nice little pictures with measurements for support shown, etc. Just stick with 12/2 it'll keep things simpler. Worst case scenario: you end up having to use it for only one circuit, but even at that, it's less than half the price of 12-2, so you're still ahead. Assuming you're getting your shop inspected and doing this under a permit, I'd ask your local inspector about it, but you should be fine. Some inspectors might want to see a separate ground conductor for each circuit. They might only use 100 feet of it, and they might run into problems justifying their specific use of it to an inspector, especially if they're using it to feed split circuits. The reason I said I'd avoid it (I think - it was over a year ago) was that unless that person was using it a lot, investing in it wasn't a good idea, especially for someone rewiring their own house. I'd have to assume it's stolen, so do what you will with that. $60 is less than 1/2 the price of 12-2, and it's 1/12 the retail price of 12-2-2. You could, if needed, use the 12-2-2 for one 120v circuit and one 240v (no neutral, such as for a welder) circuit, as long as they initially go to a single box to splice the ground to both circuits. You have to have a separate neutral for each hot. Well, you can only use it for 2 runs, unless you're using a 3-phase service.
