In my research for the grinder build, I decided on 12 gauge wire to go from VFD to motor. (using 10 gauge to power VFD)
I was told that 12-3 wire actually has 4 wires so that's what I ordered in cord form. I checked the Home Depot site and the Romex 12-3 IS showing 4 wires but the 12-3 power cord (wire by the foot) that I purchased only has 3 wires. (never noticed it until now that I OWN it!)
Is that a common thing??? I did want the ground wire inside the cord but screw it, now I'll just ground the motor to the grinder/cart and another ground at the VFD location to the cart. Since the motor is bolted on anyway, it's all grounded but I'll do the wire for good sportsmanship. I tried!
Google search says 12-3 wire is 4 wires! Guess either cord is different or Home depot is in error.
Curious what our electricians here have to say. Do we have any????
