Understanding USB Outlets

USB outlets are a practical solution to the growing number of devices that require USB charging. These outlets combine standard electrical sockets with built-in USB ports, allowing you to plug in both traditional appliances and USB-powered devices simultaneously.

Benefits of USB Outlets

Installing USB outlets in your home offers several advantages:

• Convenience: Charge devices without adapters
• Space-saving: Eliminate the need for bulky charging blocks
• Efficiency: Some USB outlets provide faster charging than standard adapters
• Aesthetics: Create a cleaner, more streamlined look in your living spaces

Types of USB Outlets

There are various types of USB outlets available on the market. When selecting a USB outlet, consider the types of devices you’ll be charging and the specific requirements of the installation location.

• Dual USB-A ports with standard outlets
• Combination USB-A and USB-C ports
• High-amperage outlets for faster charging
• GFCI-protected USB outlets for use in kitchens and bathrooms

In his kitchen, Eastman installed a Leviton 3.6A USB Dual Type A In-Wall Charger with 15 Amp Tamper-Resistant Outlet in black. 

Special Considerations for USB Outlets

When installing USB outlets, there are a few additional factors to keep in mind to ensure safety and compliance with local codes.

GFCI Protection

Normally, in a kitchen, receptacles need to be ground fault circuit interrupters (GFCIs) or at least have GFCI protection. In this case, Eastman already has a GFCI receptacle upstream in his wiring, so his new receptacle is still protected. However, if yours is not, or the receptacle being replaced is a GFCI, be sure the new receptacle is a GFCI as well.

Arc-Fault Protection

Eastman mentions in the video that in some jurisdictions, replacing an outlet in an existing dwelling requires upgrading to arc-fault protection. Check with a licensed electrician to determine if this applies in your area. If it does, you’ll need to hire a licensed professional to install it.

Amperage and Compatibility

Ensure that the USB outlet you choose is compatible with your existing wiring and circuit amperage. Most USB outlets are designed for 15-amp circuits, but always verify before installation.

Preparation for USB Outlet Installation

Before beginning the installation process, gather the necessary tools and materials and take proper safety precautions.

Tools and Materials Needed

To install a USB outlet, you’ll need the following:

• USB outlet
• Phillips screwdriver
• Flathead screwdriver
• Wire strippers
• Voltage tester
• Pliers
• Electrical tape
• New cover plate (if necessary)

Safety Precautions

Working with electricity can be dangerous. Follow these safety measures:

• Turn off power at the main breaker.
• Use a voltage tester to confirm power is off.
• Use tools with insulated handles.

All electrical projects present a shock hazard, so Eastman suggests only tackling a project like this if you feel comfortable doing it. If not, hire a licensed electrician.

Step-By-Step USB Outlet Installation Process

Installing a USB outlet is a straightforward process that can be completed in about 30 minutes. Follow these steps carefully for a safe and successful installation.

Step 1: Shutting Off Power

1. Locate the circuit breaker controlling the outlet you’re replacing.
2. Switch off the breaker.
3. Use a voltage tester to verify that power is off at the outlet.

Step 2: Removing the Old Outlet

1. Remove the cover plate using a flathead screwdriver.
2. Unscrew the old outlet from the electrical box and carefully remove it.
3. Identify the wire connections—black (hot), white (neutral), and green or bare (ground).
4. Loosen the terminal screws and remove the wires.

Step 3: Connecting the New USB Outlet

1. Strip the ends of the wires if needed, using the strip gauge on the new outlet as a guide.
2. Connect the ground wire to the green screw or ground terminal.
3. Attach the white wire(s) to the silver terminal(s).
4. Connect the black wire(s) to the brass terminal(s).
5. Tighten the screws and ensure all connections are secure.

Step 4: Securing the New Outlet

1. Gently fold the wires back into the electrical box.
2. Push the new outlet into place.
3. Secure the outlet to the box using the provided screws.
4. Attach the new cover plate.

Step 5: Testing the Installation

1. Turn the power back on at the breaker.
2. Use a voltage tester to confirm power is flowing.
3. Test both the standard outlets and USB ports by plugging in your devices.

Troubleshooting Common USB Issues

Even with careful installation, you may encounter some issues. Here are some common problems and their solutions:

• Outlet not working: Turn off the breaker, double-check all wire connections, and turn the breaker back on.
• USB ports not charging: Verify that the device is compatible with the USB outlet’s amperage.
• Slow charging: Consider upgrading to a higher amperage USB outlet.
• Overheating: Discontinue use and consult an electrician, as this could indicate a wiring problem.

Maintenance and Care

To keep your USB outlet functioning properly, check periodically for loose connections and clean the USB ports gently with compressed air to remove dust. Avoid overloading the outlet with too many high-powered devices, and promptly replace the outlet if you notice any signs of damage or malfunction.
