5 Reasons Not to Run Extension Cords Under Rugs

Flat cords still trap heat Carpets and rugs act as insulation. Even flat extension cords can overheat under a rug, especially under load.

Round cords are worse but not safe Round cords are thicker and trap more heat, but flat cords are not a safe alternative. Both create a fire hazard.

Foot traffic damages insulation over time People walking on a cord hidden under a rug gradually wears down the insulation. You won’t notice the damage until it arcs or shorts.

You can’t see the damage A cord under a rug is out of sight. By the time you smell smoke or see a problem, the cord may already be failing.

There is no safe extension cord for under a rug This is not a shopping decision. No extension cord is designed to be run under a rug or carpet. The only safe option is to route the cord around the rug.
