Extension Cord Safety: What to Do and What to Avoid

Extension Cord Safety: What Not to Do

  • Purchase only cords that have been approved by an independent testing laboratory.
  • For outdoor projects, use only extension cords marked for outdoor use.
  • Read the instructions (if available) for information about the cord's correct use and the amount of power it draws.
  • Select cords that are rated to handle the wattage of the devices with which they'll be used. A cord's gauge indicates its size: The smaller the number, the larger the wire and the more electrical current the cord can safely handle.
  • Also consider the length you'll need. Longer cords can't handle as much current as shorter cords of the same gauge.
  • Choose cords with polarized or three-prong plugs.
  • For use with larger appliances, thick, round, low-gauge extension cords are best. For smaller appliances and electronics, you can use thin or flat cords.

Using extension cords

  • Never remove an extension cord's grounding pin in order to fit it into a two-prong outlet.
  • Avoid powering multiple appliances with one cord.
  • Never use indoor extension cords outdoors.
  • Don't plug multiple cords together.
  • Don't run extension cords under rugs or furniture.
  • Never tape extension cords to floors or attach them to surfaces with staples or nails.
  • Don't bend or coil cords when they're in use.
  • Cover unused cord receptacles with childproof covers.
  • Stop using extension cords that feel hot to the touch.

Caring for extension cords

  • Always store cords indoors.
  • Unplug extension cords when they're not in use.
  • Throw away damaged cords.
  • Pull the plug—not the cord—when disconnecting from the outlet.

And remember that extension cords are intended as temporary wiring solutions. If you find you're using them on a permanent basis, consider updating your home's electrical system.
