I've got a multimeter.
I have an outlet with 3 openings spaced 60deg around the outer edge with a hole in the middle (which may be for a recessed screw? can't see into it it is out of the way behind a dryer).
I think it looks a LOT like this: http://www.justanswer.com/uploads/Ed...yer_outlet.jpg
It is wired into the panel but I haven't taken the panel apart to see whats up. Is there a simple way to test if the outlet is live with 220 or 240v using the multimeter? If so, what goes where and what reading would I be looking for?
Any advice is appreciated. Thanks!
