Electrical

Electrical systems deliver power safely to every outlet, light, and appliance. Most electrical work carries fire and shock risk, so the guidance here stresses when to call a licensed electrician.

Topics

• Panels and service — The electrical panel distributes power from the utility service to the home's circuits.
• Wiring and outlets — Outlets, switches, and wiring make up the everyday electrical system.
• Lighting and switches — Lighting controls include switches, dimmers, and smart devices.
• EV chargers and generators — EV chargers and home generators add significant electrical loads or backup power.

Before you hire

Confirm the contractor holds the license your state or city requires, carries liability and workers' compensation insurance, and pulls permits for work that needs them. Get written estimates that spell out materials, labor, and warranties.
