Line And Load Gfci

In the above diagram load is not connected to the gfci i e.

Line and load gfci. One set of wires will be the line or power supply. 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. Load essentially means using the protected power opposed to supplying the power. Connect the black line hot wire to the brass screw marked line by inserting the wire into the back wire hole.

Line and load have special meaning when wiring ground fault circuit interrupter gfci outlets. Protected receptacle s will be connected to the gfci load side as shown below. The differences are pretty straightforward but i made. Separate the wires from the box into two pairs.

Ground fault circuit interrupters gfci s implement line. Other outlet switches and additional load is not protected by the outlet. The line terminals and the load terminals. In gfci the load and line terminals marking should be verified by the nameplate date rating printed on it or by user manual provided by the manufacturer.

Ground connection is not shown. In this video i talk about the difference between the line and load on a gfci electrical receptacle. One pair is marked line and one is marked load. Gfcis have two pairs of screw terminals for connecting wires.

Gfci receptacle with one standard receptacle connected to its load. Power is connected to the gfci line side. Line and load terminals are also clearly marked on a ground fault interrupting outlet because the outlet contains a breaker that interrupts the current when it detects a current surge. When you connect only to the line terminals the outlet provides gfci protection only for itself.

A gfci outlet properly installed will protect all the outlets on the load side. Interchanging the line and load wires on a conventional outlet has no effect on the outlet but doing so on a gfi outlet renders the breaker ineffective and creates a dangerous situation because the outlet won t. The other set will be the load which carries power to additional outlets on the same circuit. When it comes to ground fault circuit interrupter or gfci outlets there is always a question as to how to connect the wires this is because gfcis have two different sets of terminals.

Tighten the terminal screw.
