How To Replace A Gfi Outlet

GFI outlets are an essential part of any electrical system. They protect you from electrical shocks and are required by law in certain areas of your home. However, if you notice that your GFI outlet has stopped working, it’s important to replace it as soon as possible. In this article, we’ll guide you through the steps on how to replace a GFI outlet.

Gather the Necessary Tools

Before you begin replacing your GFI outlet, you’ll need to gather a few tools. You’ll need a screwdriver, wire cutters, wire strippers, and a voltage tester. These tools will help you safely replace the outlet without damaging any other components in your electrical system.

Turn Off the Power

Before you begin any electrical work, it’s essential to turn off the power to the outlet. Locate your home’s electrical panel and turn off the circuit that powers the GFI outlet. Once you’ve done this, use the voltage tester to ensure that there is no power flowing to the outlet.

Remove the Old Outlet

Use the screwdriver to remove the cover plate from the old GFI outlet. Then, use the screwdriver to remove the outlet from the electrical box. Carefully pull the outlet out of the box, taking care not to damage any of the wires attached to it.

Disconnect the Wires

Using the wire cutters and wire strippers, carefully disconnect the wires from the old GFI outlet. Take note of which wire is connected to which screw on the outlet, as you’ll need to reconnect them to the new outlet in the same configuration.

Prepare the New Outlet

Remove the new GFI outlet from its packaging and carefully read the manufacturer’s instructions. Using the wire strippers, strip the ends of the wires that will be connected to the new outlet. Follow the manufacturer’s instructions to ensure that you prepare the outlet correctly.

Connect the Wires

Carefully connect the wires to the new GFI outlet, making sure to connect them to the correct screws. Tighten the screws on the outlet to ensure a secure connection.

Attach the Outlet to the Electrical Box

Carefully push the wires back into the electrical box, taking care not to damage any of them. Use the screwdriver to attach the new GFI outlet to the electrical box, securing it in place.

Test the Outlet

Once the new GFI outlet is securely in place, turn the power back on at the electrical panel. Use the voltage tester to ensure that there is power flowing to the outlet. Then, test the outlet by plugging in a small appliance or lamp.

Replace the Cover Plate

Once you’ve tested the new GFI outlet and confirmed that it’s working correctly, replace the cover plate. Use the screwdriver to secure the cover plate in place.
