Hacker- If you got nailed by a light switch that was 110/115, you'd have to go to the fuse/breaker box and grab on to both "legs" of the service if you want to check out 220.... lol. Or something like a dryer or stove line, I have most of my shop tools like my air compressor, table saw and welders wired to 220, you draw half the amperage that way.
I get what your saying now ABQ, Im a little dodgy on the current thing. I always think in volts and amperage, I do wish I had gone to school for electronics, I like fixing stuff. Theres really not the demand nowadays because everything is disposable. TV goes, buy a new one, stereo goes, buy a new one. I remember when there was electronic repair places everywhere, now its nearly impossible to find one. I have a Kenwood individual component stack system that needs the CD player fixed, it doesnt pick up the CD's anymore. Then it seems these DVD players are junk, have one of them that the tray doesnt open.
