Safety first

Turn off the breaker and verify power is off before working. If you are not comfortable, hire a licensed electrician.

Step-by-step
1

Turn off the breaker and confirm power is off.

Non-contact voltage tester held against an outlet slot to check for power
Touch a non-contact tester to the outlet or wires. No light or beep means the power is off.
2

Identify the LINE (feed) wires and LOAD (downstream) wires if protecting additional outlets.

The wires coming from the panel go on LINE. Only use LOAD if you want outlets further down the line protected too.
3

Connect LINE black to the brass LINE terminal and LINE white to the silver LINE terminal.

4

If protecting downstream outlets, connect LOAD black and white to the LOAD terminals.

5

Connect the ground wire to the green screw.

Match colors: black to black, white to white, bare copper to bare copper. Twist a wire nut on each pair.
6

Secure the GFCI in the box, install the cover, and turn the breaker on.

7

Press the TEST button; the outlet should trip. Press RESET to restore power.

Pro tip for you

The TEST and RESET buttons should be used monthly to make sure the GFCI works.
