5 Things to Know Before Burying an Extension Cord

Standard extension cords are not rated for burial Regular indoor/outdoor cords will degrade underground, letting in water and causing short circuits or fires.

Use a cord marked “direct burial” or “UF” if you must bury it These cords have thicker insulation designed for underground use.

Bury direct burial cords at least six inches deep For extra protection, run the cord through PVC conduit, but never place it under concrete or heavy traffic areas.

Low-voltage landscape lighting is a safer alternative It costs less, poses no shock risk, and its wire can be buried just an inch or two deep.

For temporary use, lay the cord on the ground instead Cover it with mulch or a rug, but do not bury it—that is the step that causes failure.
