Upgrading to USB outlets only requires simple wiring identical to installing any standard duplex receptacle. Inside the electrical box, you connect the outlet’s hot line to the black wire, neutral line to white wire, and ground to either the green wire or metal box itself using screws or push-in connectors. No specialty tools or electrical knowledge necessary! Many USB outlets even include snap-on wall plate covers to replace your current switch plates for quick cosmetic upgrades. Some models like Leviton’s feature slim designs that fit comfortably in existing receptacle boxes too during renovations. As with any electrical work, exercise safety precautions by turning off home power at the breaker box before wiring.
