3 Reasons to Never Use an Indoor Extension Cord Outdoors
Moisture damages indoor cords Even dry outdoor air contains moisture that condenses inside the cord over time, leading to shorts or fire.
Sunlight cracks the insulation UV rays slowly degrade the cord’s jacket, causing invisible cracks that can expose live wires.
Temperature swings cause failure Indoor cords aren’t built for ground moisture or outdoor temperature extremes, and temporary use always becomes permanent.
