Question:

old appliance with two hot wires and one neutral 220 volts, new wiring, has ground, neutral, and hot?

I have a 220v single phase kiln with two red wires labeled L1 and L2, and one white wire labeled N. It did not come with the plug, so I bought one and new wire 3/c 10awg, but it has ground(green), Hot(black), and neutral(White). I dont know how to proceed with wiring? any help would be great. Thanks. Jose

Answer:

Wire L1 L2 to the spade looking terminals, and the n to the round pin.
How 220v works with 4 wires: (one wire to each) 1 Black wire carries 110v (L1) 1 Red wire carries 110v (L2) 1 White wire acts as a common (neutral) 1 Green wire acts as a ground How 220v works with 3 wires: 1 Black wire carries 110v 1 Red/White wire carries 110v (if you use white flag it with red electrical tape) 1 Green wire acts as a ground/common (Do not actually ground this) If you have 4 wires in the wall, but you are wiring them to a 3 prong receptacle, connect the green wire to the green ground screw on the receptacle or if no ground screw is present, attach this wire to one of the receptacle mounting screws. That way if the common fails, you still have the added protection of a ground. Some wiring installations may use different colored wires, this doesn't change how anything works. If you have any doubts, get a voltage tester and make sure.
Sure you don't have a 110 volt cord? Hook one red to black. One red to white.
