Oh, I realize that. But now they can shovel it less often, and do it from the ground with one of those long scooper things much more easily.

I think it's more that the implementation of roundabouts in Minnesota is lovely. Poor signage, etc. There are a bunch of roundabouts under Hwy 169 where the main route on W 78th is very poorly labeled. The road jogs around a lot and the signs are all for roads that don't go where any human being would want to go. They're also used to slow traffic instead of being useful. I understand them when 7 roads meet, but these are 4 way interchanges. A stop sign works fine.

Four way stops in Minnesota are WAY worse than roundabouts. Nobody knows when to go... EVER. Down here by the Iowa border, the roundabouts on 169 are okayish enough. We even see people with Iowa license plates make it through them just fine. Waiting for a grain hauler to get through one of them is a pain in the rear end though. Ok... back I go to the page I came from.

The roof rake wouldn't work as well or at all with the way he uses the hook. He can shovel with a bit of help from gravity. The roof rake requires him to get it up and over the snow and pull it downward, which is a lot harder than being up there with a shovel and just pushing the snow off.

BTW, he used the chainsaw rig once. He got about ten seconds into using it and realized, "I have made a huge mistake." He managed to disengage it from the log he had cut into, set the death trap down without sawing his toes off somehow, and turned it off. He was also alone in the woods behind his house at the time, which I'm sure thrilled his wife to no end when she found out later. She, as you may be able to tell, has the patience of a saint.

There's just something very OSHA about him. He is bound and determined to not be limited by his handicap, and that's understandable, but he absolutely cannot separate "things I can technically manage to do" with "things I should do."

I looked at it a minute. Then I looked again. Then I went OOOOOHHHHHHH!!!

Only upshot - if you plugged that in, the load wouldn't operate normally. If it was a motor you'd be sort of single-phasing it and the protection would trip because it would pull a ton of current.

You'd also get a pretty good amount of current flow through the ground. Depending on the feed you may get lucky and cause a ground-fault trip upstream. Those are set to detect ground fault currents in the ampere range, not milliamps like the ones in your kitchen.

I'm still somewhat in the dark. Does it have to with the green (I'm assuming ground) and the yellow going to the same terminal?

That's one wire - green/yellow. Green/yellow is ALWAYS ground. In this case it connects to the chassis of whatever is on the left side of that plug.

The green/yellow wire is connected to "Z", that's one of the three hot wires. If you plug that in, the chassis of whatever that plug is wired to (like a motor casing) will become live with 277 volts. This is probably the worst-case screwup. If you plug the device in and touch the case you're almost guaranteed to get one hell of a shock.

Also, you need to be careful with three-phase plugs. If you have a motor and swap any two of the three hot wires, the motor you're connected to will spin in the opposite direction. This doesn't matter what type of motor - induction or synchronous. In a lot of cases that's a problem if a motor runs in the opposite direction you expect. We had to do special testing at work when commissioning equipment (14kV) to ensure the correct phase rotation.

Three-phase that was what I thought too after two days of intermittently plugging it in and troubleshooting the hoist. But no, the busbar fuses never blew and I kept unplugging it, looking for switches or wires rubbing inside the panels, nothing. Then I walked away to look for a mechanical drawing, believing I had ruled out any possibility of an electrical problem and returned to a wide eyed engineer asking "is this nut supposed to be smoking? Have you guys been welding over here?"

Not on purpose bro.

E: and yes, the ground teminal on that plug is painted bright green on the back how the gently caress did someone gently caress that up

Go full John Snow if there's enough spare cable. Get a pair of wire cutters and cut the cable off and take the plug with you. (Don't do this while it's plugged in!)

Also that's sounds like a really, really serious screwup we're talking about here. I'm not saying fire-on-the-spot (as tempting as it may be) but this is something that absolutely should not happen when you've got someone competent doing your wiring.

I would treat that system like it's dangerous until proven otherwise.
