Extension Cords

Select a length that reaches without excessive slack; longer cords require thicker wire (lower gauge number) to prevent voltage drop. For light-duty household tools use 16 AWG for up to about 50 feet, 14 AWG for medium loads up to about 75 feet, and 12 AWG or thicker for heavy tools or longer runs

Look for cords with grounded three-prong plugs, heavy-duty insulation (rubber or thermoplastic elastomer), strain relief at ends, and ratings for outdoor or wet-location use (e.g., SJTW/SJEOW markings). Ground fault circuit interrupter (GFCI) protection is recommended when working in damp environments

Check the tool’s amperage or wattage on its nameplate, then choose a cord gauge and length that safely carry that current (refer to an ampacity chart). Ensure the cord's voltage and amperage ratings meet or exceed the tool's requirements

Yes. Outdoor cords are labeled for outdoor use and built with weather- and UV-resistant jackets (e.g., SJTW, SJEOW), while indoor cords have lighter insulation and are not rated for exposure to moisture, sunlight, or extreme temperatures

Coil cords loosely without tight bends, avoid kinking, keep connectors clean and dry, inspect for cuts or exposed conductors before each use, and store them off the ground in a dry, cool place away from direct sunlight and chemicals

Replace a cord if you see frayed or exposed wires, melted or discolored insulation, cracked plugs, sparking or intermittent connections, or if the cord becomes excessively hot under normal load

Industrial cords typically cost more because they use thicker conductors (lower AWG), tougher jackets for abrasion, oil and chemical resistance, and higher temperature ratings; prices commonly range from budget options under $50 to premium styles above that depending on length and specifications
