Home electrical safety checklist

A few simple habits and a short monthly check cover most of what homeowners can do to keep electricity safe at home. Anything beyond these checks belongs with a licensed electrician.

Monthly checks

• Test GFCI outlets with the TEST and RESET buttons. ESFI recommends testing them monthly.
• Test AFCI breakers or outlets with their TEST button. ESFI recommends monthly testing using the built-in button.
• Test smoke alarms and carbon monoxide alarms with their test buttons.

Smoke and carbon monoxide alarms

• The National Fire Protection Association (NFPA) recommends smoke alarms inside each bedroom, outside each sleeping area and on every level of the home.
• Replace smoke alarms when they’re 10 years old. The date is printed on the back.
• Homes with gas appliances, a fireplace or an attached garage should have carbon monoxide alarms. Replace them according to the manufacturer’s schedule.

Outlets and cords

• Plug major appliances, such as refrigerators, washers, dryers and space heaters, directly into a wall outlet, not an extension cord or power strip.
• Never plug extension cords into each other, and use outdoor-rated cords outside.
• Don’t run cords under rugs or furniture, where damage can go unnoticed.
• Replace cords that are cracked, frayed or have damaged plugs.
• Use bulbs at or below the wattage rating on light fixtures and lamps.
• In homes with young children, tamper-resistant outlets add protection.

Warning signs

ESFI says flickering or dimming lights, a burning smell, discolored switches or outlets that feel warm can be signs of a serious wiring problem. Breakers that trip repeatedly or outlets that spark are also reasons to call a licensed electrician.
