Attach the red wire to the other terminal.Connect the black (hot wire) to any of the brass terminal screws.Attach the green wire (ground) to the ground terminal, which is usually the green screw on the plug.Step five: Connect the stripped wires to the new outlet The neutral wire should be disconnected from the breaker board. The modern 220v outlet usually comes with 4 wires, two hot wires (black and red), one neutral (white wire) and a ground wire (green).īut since we are wiring a 3 prong outlet, we will make use of three wires, the green, red and black wire. But if you don’t have a 220 v power system before, you will first install a metal box before mounting the 220-volt plug. Using your screwdriver, loosen the screws and remove the old outlet. The reading should be zero to proceed to the next step. You can do that by inserting the two probes of your multimeter in the ports of the outlet. Step two: Test the outlet with a multimeter.Īfter turning off the breaker, confirm that the outlet is off with your multimeter. The circuit breaker is usually installed inside the main breaker panel, and you can switch it off by flipping the breaker to the off position. This is to make sure that the circuit is dead and could not lead to electrocution when you touch it. Step one: Turn off the power sourceīefore embarking on any installation, it is wise to turn off the breaker. Once you are through with that, you can move on with the next steps.
