i'm wiring up the parts to build my rotary phase converter and i have a few questions. i've done some 120V house wiring, but not much 240V or 3-phase wiring.
i bought a 20' piece of #8 3-conductor cable to use as the cord on the converter. the wires are white, black and green. i am plugging this into a 50A welding outlet. the outlet is for a three-prong plug (one vertical prong and the two lower ones are angled). when wiring the plug, the instructions state to connect the white (common) wire to the center vertical prong. that leaves a black and a green wire. from anything i've heard, the green wire is supposed to be a ground. so am i supposed to have a red wire in here to make this thing match what the NEC says?
also, since i only have three wires, which one is supposed to ground the metal enclosure i am putting this stuff in? or does this wiring scheme not get grounded?
i am a bit confused by this.
