4 Things to Know About Flat vs. Round Extension Cords Under Rugs
Use a flat cord, not a round one Round cords create a noticeable lump under a rug, which is the trip hazard you are trying to avoid. Flat cords are low-profile and lay flush against the floor.
Running any cord under a rug is a fire risk Heat gets trapped under a rug, especially if it is thick or has furniture on top. A flat cord reduces the lump but does not eliminate the risk of overheating.
If you must do it, use a properly rated flat cord Get a flat cord with a gauge rated for the load you are drawing. Do not cheap out on the cord’s capacity.
Better alternatives exist Route the cord along the baseboard or use a floor cord cover instead. Avoid covering the cord with anything heavy.
