How to Replace a Standard Outlet with a USB Outlet: Step-by-Step Guide

Quick Answer

To replace a standard outlet with a USB outlet, first turn off power at the breaker, then remove the old outlet, connect the wires to the new USB outlet, and mount it in the box. For best results, choose a model with USB Type A and Type C ports, like the radiant® GFCI USB Outlet with SafeLock® Protection, which also adds GFCI safety in wet areas.

In today's connected world, having a USB outlet in your home is more than a convenience—it's a necessity. Whether you're charging your phone, tablet, or earbuds, a USB wall outlet eliminates the need for bulky adapters and frees up standard outlets for other devices. This guide will walk you through the process of replacing a standard outlet with a USB outlet, ensuring a safe and efficient upgrade.

Before you start, it's important to understand the basics of electrical work. Always prioritize safety: turn off the power at the circuit breaker and use a voltage tester to confirm the power is off. With the right tools and a little patience, you can complete this project in under an hour. We'll also highlight some excellent USB outlet options from Legrand that combine safety, convenience, and style.

Tools and Materials You'll Need

Before beginning, gather the necessary tools and materials. You'll need a flathead and Phillips screwdriver, a voltage tester, wire strippers, needle-nose pliers, and a USB outlet that meets your needs. If your existing wiring lacks a ground wire, you may need to consult an electrician, as most modern USB outlets require a ground connection for safety.

When choosing a USB outlet, consider the charging speed and port types. USB Type A is standard, but USB Type C is becoming the norm for newer devices. Some outlets offer both, providing maximum compatibility. Additionally, look for tamper-resistant shutters if you have young children, and consider GFCI protection if the outlet will be installed in a bathroom, kitchen, or outdoor location.

• Voltage tester to ensure power is off
• Wire strippers for preparing wires
• Needle-nose pliers for bending wire hooks
• USB outlet with USB Type A and Type C ports for versatility

Step-by-Step Installation Process

Start by turning off the power to the circuit at the breaker panel. Use a voltage tester to confirm that the outlet is not live. Remove the wall plate and unscrew the outlet from the electrical box. Carefully pull the outlet out, taking note of the wire connections. Typically, you'll see black (hot), white (neutral), and bare copper (ground) wires.

Disconnect the wires from the old outlet, then connect them to the new USB outlet. Connect the black wire to the brass terminal, the white wire to the silver terminal, and the ground wire to the green terminal. If your new outlet has push-in connectors, you can use those instead, but ensure the wires are securely inserted. Gently push the outlet back into the box, screw it in place, and attach the wall plate.

• Double-check that the power is off before touching any wires.
• If the wires are damaged, trim and strip them to ensure a clean connection.
• Use a torque screwdriver if available to avoid over-tightening terminals.

Choosing the Right USB Outlet

Not all USB outlets are created equal. When selecting a model, consider the amperage and charging speed. For example, the radiant® GFCI USB Outlet with SafeLock® Protection, Type A/C, 20A, Tamper-Resistant, Gray offers both USB Type A and Type C ports, allowing you to charge a variety of devices quickly. Its 20A tamper-resistant receptacle ensures safety, making it an excellent choice for kitchens and bathrooms.

If you're looking for a more budget-friendly option, the radiant® Tamper-Resistant 20A Duplex Self-Test GFCI Receptacle with SafeLock® Protection, Light Almond provides GFCI protection with a self-test feature that runs every 3 seconds, ensuring continuous safety. While it doesn't include USB ports, it's a great choice for replacing standard outlets in areas where you don't need USB charging but want enhanced safety.

Safety Considerations and Common Mistakes

One of the most common mistakes when installing a USB outlet is not turning off the power at the breaker. Always verify with a voltage tester. Another mistake is over-tightening the screws, which can damage the outlet. Additionally, ensure that the wires are properly stripped and inserted; loose connections can lead to arcing and potential fire hazards.

If you're installing a GFCI USB outlet, remember that GFCI protection is crucial in wet locations. The SafeLock® Protection feature ensures that the outlet is not functional if GFCI protection is lost, providing an extra layer of safety. Always follow the manufacturer's instructions and local electrical codes.

• Never work on a live circuit.
• Use a wire stripper to remove the correct amount of insulation (about 3/4 inch).
• If you're unsure about any step, consult a licensed electrician.

Step-by-Step Installation Guide

1. Turn Off Power: Locate the circuit breaker that controls the outlet and switch it off. Use a voltage tester to confirm the power is off before proceeding. Checkpoint: The voltage tester should read zero volts.
2. Remove the Old Outlet: Unscrew the wall plate and the outlet from the electrical box. Carefully pull the outlet out, noting the wire connections. Common mistake: Forgetting which wire goes where—take a photo before disconnecting.
3. Disconnect Wires: Loosen the terminal screws and remove the wires from the old outlet. If the wires are damaged, trim and strip them. Checkpoint: Ensure the wires are clean and not frayed.
4. Connect the New USB Outlet: Attach the black wire to the brass terminal, the white wire to the silver terminal, and the ground wire to the green terminal. Tighten screws securely. Common mistake: Over-tightening can strip threads; tighten snugly but not excessively.
5. Mount the Outlet and Attach Wall Plate: Gently push the outlet into the box, align it, and screw it in place. Attach the wall plate and turn the power back on. Final test: Plug in a device to verify charging and test GFCI if applicable.
