I need 220 at a 110 outlet. I found that 220 needs 3 wires, black red and white. The white always goes to the silver screws and the black and red are hot. The problem it says in my book that the green screw is the ground. But I dont need a ground, so I just hooked the red wire to the green screw. The outlet worked fine when I tested it, but when I shoved it in the wallbox, it sparked and blew the breaker. That wasn't supposed to happen and the wires are tight. Here is how I wired it (below).
At first I thought I had a bad breaker so I held the breaker tight so it would not blow. I figured if there was a crossed wire it would just burn the bad part of the wire off. But it still blew. This is making me angry. I pulled the outlet back out of the wallbox and now it works again. Maybe I will just let it hang out of the wall since it works that way but want to find out why.
BLACK [] [] WHITE (to silver screws)
