Let’s get right to it. Here is what you will need: A flat head screwdriver, a Phillips (cross point) screwdriver, needle nose pliers, a flashlight, and a replacement GFCI.
1: Turn off the power at the breaker box. This is the most important step.
2: Remove the face plate with screw driver.
3: Remove the 2 screws connecting the outlet to the housing. Keep these for later.
4: Pull the outlet away from the housing so you can see all 5 wires. This might require more pressure than expected.
5: Use screwdriver to loosen all 5 screws. They do not need to be removed, just loosened.
6: Using needle-nose pliers , pull the white and black wires out of the outlet. Keep the wires in the proper order- top and bottom. Then, remove the plain copper wire from the bottom of the outlet.
7: Retrieve the new outlet. To connect, select a wire and insert it into the rear of the outlet. Push it in then tighten the screw.
8: Repeat. Remember, the white wires go into the rear left side (top and bottom) and the black wires go into the rear right side (top and bottom).
9: Connect the copper wire the the bottom of the new outlet. Tighten the screw.
10: Push the outlet back into the housing. The copper wiring is very stiff, so this might require more pressure than expected.
11: Reconnect the outlet to the housing unit with the two screws removed earlier.
12: Turn on the power at the breaker box.
13: Test the outlet with a GFCI tester. If you do not have one, you can test the outlet with the test button and reset button.
14: If all is well, replace the outlet face plate.
15: You’re all set!
P.S. Remember, you are working with real electricity. Do not attempt to adjust or alter the outlet with the power on or without taking proper safety precautions. Be safe, be smart, and be PROUD of what you can accomplish!
