I've been working through the mess of electrical in a pole barn on my new property. Honestly the guy went way overboard in most cases, such as every single outlet is on it's own circuit. Lots of cost cutting too like a recycled Federal panel and many two pole breakers but each side feeding a different plug. Breakers are $25 a pop for this thing and he's already recycled the panel so I get it. I decided to finish off a couple outlets the P.O. didn't & pull all the outlets one at a time to make sure everything is tight before I just assume it's good. Imagine my surprise when I see this. The hot is right, but the neutrals are connected and the neutral screws connected to the ground? I think to myself WTF? This isn't right at all. But no big deal, I'll just correct the wiring.
So I do. I snug it up all grounded and feeling smug to myself. Plug in my old CO detector because it beeps when the power goes on. Go flip the breaker. "Beep... BANG!"
Err, that's not right. Shut the breaker off, go look at the plug. CO detector smelling all sorts of wrong. Recheck my work, looks good. Open the panel; They've got the white wired to another breaker and didn't mark it in the box. I'd just created a 240v plug.

So I have no idea where the other wire in this box goes off too but it was clearly a 240v feed to something, and farmer Joe wanted to put a 120 right here. Because both wires were hot and both were on the same twin breaker when I shut off "Plug 6" I shut off both sides of it. And of course when I put a lamp in it as-was it worked. Would I have fried one of those plug-in testers? I guess it would have detected the neutral / ground connection here?
