What is the proper way to wire a three prong 220 Volt outlet? The outlets I bought have two screws for the hot legs and then one green screw. I was assuming I just wouldn't use the ground wire since I pulled 12/3 but am now wondering if I should use the ground wire and not use the neutral leg for these outlets.
Thanks is advance for everyone's help. These three prong outlets match all of my 220 equipment so I won't be changing to a four prong configuration.
