Extension Cords

Be on the safe side: use extension cords properly at all times and know these guidelines.

  • Use extension cords only on a temporary basis.
  • Always use an extension cord that can be grounded and has a duty rating appropriate for the job.
  • Use extension cords that have a seal of approval from a major testing laboratory, such as Underwriters Laboratories (UL).
  • Never use a tool with a three-prong grounding plug on an extension cord that only accommodates two prongs.
  • Use only extension cords approved for outdoor use when outdoors.
  • Use one long cord instead of several shorter lengths. The longer the extension cord is, the larger the wire diameter needs to be - typically, thicker is safer.
  • Protect your cords from heat, chemicals, oil, etc.
  • Store extension cords in a dry place, coiled loosely.
  • Never nail or staple an electrical cord in place or run cords under rugs.
  • Inspect cords regularly for damage. Replace damaged, cracked or frayed cords immediately. Never patch a cord with tape.
