How to Install a USB Wall Outlet: A Novice Homeowner’s Guide
Why Install a USB Outlet?
- Convenient Charging: With built-in USB ports, you'll always have one available for your USB device.
- Space-Saving: Keep your countertops clutter-free by eliminating bulky power adapters.
- Home Value: Upgrading your electrical system can be an attractive selling point for potential buyers.
Installing a USB wall outlet is a straightforward DIY project that requires basic electrical knowledge. Let’s get started!
Safety First
Before handling any electrical components, always prioritize safety. Turn off the circuit breaker that supplies power to the outlet you’re working on, and use a voltage tester to confirm there is no electricity running to that outlet. If you’re unsure about any step, consult a qualified electrician.

Step-by-Step Installation Guide
1. Turn Off the Power
- Locate your home’s main electrical panel. (AKA Circuit Breaker Box)
- Find the circuit breaker corresponding to the room or area where you’ll install the USB outlet.
- Switch the breaker to the OFF position.
- Use a voltage tester to double-check that no power is present at the existing outlet.
Pro tip: Label or mark the breaker to prevent anyone from accidentally turning it back on while you work.
2. Remove the Old Standard Outlet
- Unscrew and remove the faceplate covering the old outlet.
- Unscrew the existing outlet from the wall box.
- Carefully pull the old receptacle away from the wall, exposing the electrical wires.
- Take a photo of the existing wiring to help you later.
Note: Outlets typically have three types of wires—hot wires (usually black), neutral wires (usually white), and ground wires (bare copper or green).
3. Disconnect the Wiring
- Loosen the terminal screws to release the wires from the old outlet.
- If the wires are attached via push-in connectors on the back, gently pull them out with needle-nose pliers.
4. Prepare and Connect the USB Outlet
- Identify the hot, neutral, and ground wire screw terminals for the new USB outlet. They are usually labeled or color-coded:
- Hot (black wire) → brass or gold screw
- Neutral (white wire) → silver screw
- Ground (bare copper wire) → green screw
- Strip the wire insulation about ½ to ¾ inch from the end. (Skip on retrofit work)
- Attach each wire to the corresponding terminal on the new outlet.
- Tighten the screws securely, ensuring there is no exposed copper outside of the connection.
5. Reinstall the Outlet
- Carefully fold the wires back into the wall box, ensuring they are not pinched.
- Align the USB outlet with the mounting holes and screw it into place.
- Attach the faceplate or wall plate.
6. Turn the Power Back On
- Return to your main electrical panel.
- Flip the circuit breaker back to the ON position.
- Test the regular power socket with your outlet tester to ensure proper wiring.
- Test the USB outlet by plugging in a device or using a USB cable to ensure it’s functioning.
Helpful Tips & Best Practices
- Choose High-Quality Outlets: Look for outlets with UL certification or an equivalent safety rating.
- Check Local Building Codes: If you live in an area with specific electrical codes, ensure you comply.
- Label or Document: Keep track of the circuit breaker for each new USB outlet you install for future reference.
Troubleshooting Common Issues
- No Power to the Outlet: Double-check your breaker or test the outlet with a different device. Ensure the wiring is correctly attached.
- Loose Wires: If wires slip out of place, tighten the terminals or use wire connectors for a secure fit.
- Physical Damage: If you notice cracked insulation or bent prongs, replace the damaged parts immediately.
