5 Signs It’s Time to Replace a Workshop Extension Cord

Exposed conductors If you see copper wire through a cut or tear in the jacket, discard the cord immediately. Visible wire means the insulation is compromised and the cord is unsafe.

Cracked or damaged insulation near plugs Check the ends where the cord meets the plug and connector. Cracks, stiffness, or soft spots here indicate wear that can lead to shorts or fires.

Bent or loose ground prong A ground prong that is bent, broken, or wobbly won’t provide proper grounding. Replace the cord rather than trying to straighten or repair it.

Water or crush damage If the cord gets wet, crushed by heavy equipment, or run over repeatedly, replace it. Internal damage may not be visible but can cause overheating.

Frequent tripping of breakers or GFCI A cord that causes breakers to trip or GFCI outlets to pop, even without visible damage, likely has internal faults. Replace it to avoid shock or fire risk.
