I have this plug, I think its 20A 240 volt, but not 100% sure. I put a meter on it, and I get 120, but only when I go from the left or right socket with the top socket. going straight across I dont get any voltage. I suspect its 120 each side, and 240 total.
My panel has it with a double breaker, is 20A on the breaker. The previous owner had an air compressor here, and its labeled that way.
I want to use it for my Grizzy planer and tablesaw. Also a compressor too. I will have to unplug each one each time to use obviously.
I currently have those all wired for 3 prong twist lock, so I would also like to switch the plug out eventually to a twist lock. I am assuming they are wired the same.
Just want to get educated and see if I need an electrician, or if I can handle.
