Electrical Extension and Power Cords

​The improper use of electrical extension and power cords can create fire, tripping or shock hazards. 

Safe practices include the following:

  • Use a UL listed extension cord that has a 3-prong plug (grounded) and a heavy duty rating

  • Ensure the power strips and surge protectors have a UL approved label

  • Plug extension cords into wall outlets

  • Connect power strips and surge protectors directly into a wall outlet

  • Run cords in low traffic areas (such as along the edge of walls or under tables)

  • Secure extension and/or power cords with wide tape to the  floor or to table legs

Unsafe practices are as follows:

  • Use of a narrow extension cord with a 2-prong plug (easily overheats)

  • Use of an extension cord as permanent wiring

  • Plugging one extension cord  into another extension cord, multi-outlet strip or tap (these may overload circuit)

  • Overloading circuits by plugging too many items into the same outlet

  • Use of "multi-plug" adaptors and other devices that allow the connection of multiple appliances into a single receptacle

  • Connecting multiple power strips or surge protectors together

  • Overloading power strips and surge protectors

  • Running extension cords  through or across doorways or under carpets or rugs (damages cord insulation – shock hazard)

  • Running extension cords across aisles, corridors or stairs

  • Dangling cords above the floor

  • Stringing cords over or wrapping cords around overhead pipes or sprinkler heads (could cause water damage)
