Adding an outdoor outlet to your home can allow you to conveniently plug in and power various appliances and devices outside. Whether you want to run lights, outdoor TVs, appliances, holiday decorations or tools, having an outdoor outlet makes it much easier than running extension cords from inside. With some basic DIY skills and the right materials, you can install an outdoor outlet in one afternoon.
What You Need to Install an Outdoor Outlet
Before getting started, make sure you have all of the necessary materials:
- Weatherproof outdoor electrical box – Select one rated for outdoor use with a cover that will keep moisture out.
- GFCI outlet – GFCIs outlets are required for outdoor installation to prevent electric shocks. Choose one rated for outdoor use.
- Weatherproof cover plate – Get an in-use cover plate made of durable plastic that seals tightly to the electrical box.
- 12/2 NM cable – Use cable specifically designed for outdoor installation. It will have UV protection and waterproof coating.
- Wire connectors – Get connectors suitable for joining the cables you are using.
- Conduit – Depending on your setup, you may need PVC conduit to run cables through.
- Screws – Use exterior grade, corrosion-resistant screws to attach the outlet and cover.
- Electrical tape
- Safety gear – This includes work gloves, safety glasses, and dust mask.
In addition to the materials, you will need basic tools like a voltage tester, screwdrivers, wire strippers, drill, hacksaw, level, tape measure, and more. Ensure you have everything before starting the project.
How to Add the Outdoor Outlet
Step 1: Turn Off the Power
Before doing any work, locate your electrical panel and turn off the main breaker so that power is shut off to the entire house. Test that the power is off with a voltage tester where you plan to install the new outdoor outlet.
Step 2: Choose the Location
Pick an outdoor location where you need to plug in appliances, tools, lights etc. It could be on the patio, balcony, garden or garage exterior. Choose a spot that is protected from direct rain.
Step 3: Cut the Electrical Box Hole
Measure and mark the exact spot for the outdoor outlet. Check for obstructions before cutting into the wall. Use a drywall saw to cut an appropriately sized hole for the electrical box.
Step 4: Run the Power Cable
Run 12/2 NM cable from your chosen starting point to the outlet box hole. If going through the wall, protect the cable by running it through PVC conduit. Use connectors to extend the cable as needed to reach the outlet location.
Step 5: Connect the Outlet Wires
Inside the outlet box, connect the power cable hot wire to the brass terminal on the GFCI outlet. Connect the neutral wire to the silver terminal. Connect the ground wire to the green terminal or box grounding screw. Use wire connectors to secure the connections.
Step 6: Mount the Outlet Box
Insert the connected outlet into the electrical box and screw it in securely. Make sure it is oriented properly so the cover plate will fit correctly. Use shims if needed to adjust the box position.
Step 7: Attach the Cover Plate
Screw on the weatherproof cover plate tightly so it forms a water resistant seal against the box. Make sure the outdoor GFCI outlet is completely protected from moisture.
Step 8: Restore Power and Test
With the outlet fully installed, turn the main breaker back on to restore power. Test that the outlet works by plugging in a lamp or other appliance. Press the “Test” and “Reset” buttons on the GFCI to confirm proper function.
Step 9: Weatherproof the Outlet
Use electrical tape to seal any gaps between conduit connections that could let in moisture. Caulk around the top and sides of the electrical box for an extra water resistant barrier.
And that’s it! With the outdoor outlet installed properly and weatherproofed, you can plug in and use your outdoor devices and power equipment safely. Always shut off the outlet’s GFCI protection before performing any maintenance or repairs. Contact an electrician if you have any doubts about the correct installation method. With this step-by-step guide, you can save on installation costs by adding a convenient outdoor outlet yourself using standard materials and basic DIY skills.
Frequently Asked Questions
Where is the best placement for an outdoor outlet?
The best placement is a location that is protected from direct rain and water contact but still allows easy access to plug in devices. Under an eave, patio cover or overhang is ideal. Mount the outlet box at least 12 inches above ground.
Can I install an outdoor outlet myself?
Yes, installing an exterior outlet is a DIY project most homeowners can tackle if they have basic electrical skills and knowledge. Make sure to follow local building codes and use an outlet designed for outdoor use.
Does an outdoor outlet need a cover?
Absolutely. An in-use weatherproof cover plate made of durable plastic is required to keep moisture out of the outlet box. Make sure it seals tightly with no gaps.
Should I use a GFCI outlet outside?
An outdoor outlet must be connected to a GFCI circuit for safety. GFCIs help prevent electric shocks which can more easily occur outside with wet conditions.
How deep should the electrical box be mounted?
Mount the outdoor outlet box deep enough that the cover plate will sit flush against the exterior wall surface. The box depth can be adjusted with extenders.
Can I use the same wiring for indoor and outdoor outlets?
No, you need special exterior electrical cable with weatherproof coating. Indoor NM cable lacks water protection when exposed to the elements outside.
Is a permit required to add an outdoor outlet?
Depending on your local regulations, you may or may not need an electrical permit. Contact your municipal building department to find out if a permit is required.

Installing an outdoor outlet is an achievable DIY project that can make working and entertaining in your exterior living spaces much easier and more practical.
