5 Things to Know About Daisy-Chaining Extension Cords

Daisy-chaining adds failure points Each connection between cords increases resistance and heat buildup, plus creates a tripping hazard.

Mismatched gauges cause overheating If cords have different wire thicknesses, the thinner one can overheat and fail under load.

Use same gauge cords only Both cords must be the same gauge—12 or 14 AWG for heavy-duty use, never thin 16 AWG lamp cord.

Keep cords fully uncoiled and off the ground Coiled cords trap heat. Connections should be elevated and never under a rug.

Buy a longer cord instead A single cord of the right length is safer and simpler than daisy-chaining.
