Wiring a GFCI outlet is a little more complicated than wiring a regular outlet but easily learned once explained. You can learn about wiring GFCI outlets in the following 7 steps.
Note: If you are replacing an existing GFCI outlet with a new GFCI outlet we suggest that you read our page about replacing a GFCI outlet.
Note: If only 1 black, 1 white and 1 green or bare wire are present in the electrical outlet box you can skip past this wiring step.
Your GFCI outlet can be used different ways. Refer to these diagram about wiring GFCI receptacles:
GFCI protection is provided at the GFCI outlet and to other ordinary outlets.
GFCI protection is provided only at the GFCI outlet.
GFCI protection is only at the GFCI outlet and ordinary outlets are not GFCI protected.
Turn your circuit breakers back on. This should restore electrical power to the new GFCI outlet but it will not work until the reset button is pushed.
Press the reset button to activate the outlet.
The back of all GFCI outlets are clearly marked line and load. It is important to know which is which before beginning. They usually come from the factory with a piece of tape covering the load connection points for further identification. Refer to the attached diagrams above about how to wire GFCI outlets for clarity or contact our in-office electrician in Mesa AZ free of charge.
The line terminals of a GFCI outlet connect to the power supply conductors that are connect at the circuit breaker or fuse box. Line essentially means supply. The line conductors are the incoming hot conductors. In most residential applications a Romex cable will be used which will include a bare (ground), white (neutral) and black (hot) conductor. GFCI outlet requirements mandate that line terminals identified by color require the white line conductor (neutral) to connect to the silver line terminal and the black line conductor (hot) to connect to the brass line terminal.
The load terminals of a GFCI outlet can be used to connect additional outlets to the same GFCI protected power. Load essentially means using the protected power (opposed to supplying the power). Load terminals identified by color require the white load conductor or conductors to connect to the silver load terminal and the black load conductor or conductors to connect to the brass load terminal.
Ground fault circuit interrupters (GFCI’s) implement line and load connections to employ an automatic trip action when a difference of electricity is detected. This is why it is imperative to put the correct conductors on the correct screws of the GFCI receptacle. If any of the wiring is not correctly connected to the right screw, the GFCI outlet will not work.
