How Do You Wire A 220 GFCI Outlet?
A GFCI, or ground fault circuit interrupter, outlet has a built-in circuit breaker to avoid potential shocks or short-outs. It works by measuring the amount of current coming in through the positive terminal and out through the neutral terminal. If there is a net difference in the two loads, it indicates that electricity is being lost, and causes the circuit to trip, shutting off electricity to the outlet. GFCI outlets typically come in the 125-volt variety, although 220-volt types are sometimes installed for use with hot tubs. Shut off the circuit for the outlet you intend to replace or install. Always shut off the power before doing electrical work. Connect the black probe of the circuit tester to the right-hand slot in the outlet and the red probe to the left-hand slot in the outlet. If the tester light glows, there is still power running through the outlet. Repeat Step 1, and double-check with the circuit tester that you have shut off the correct circuit.
