Things to Consider When Choosing a 100 ft Extension Cord
1. Wire Gauge (AWG)
Lower numbers mean thicker wires. A 10/3 or 12/3 gauge cord is ideal for high-powered tools. For lighting and small appliances, a 16/3 may suffice.
2. Amperage and Wattage Rating
Ensure the cord can handle your equipment’s requirements. Most heavy-duty cords are rated at 15 amps and 1875 watts.
3. Jacket Type (SJTW vs. SJEOW)
SJTW jackets are tough and weather-resistant. SJEOW jackets offer superior flexibility in extreme temperatures and chemical resistance.
4. Lighted Ends
Helpful for instantly confirming if the cord is live, especially in low-light or remote setups.
5. Temperature Resistance
If you work in cold climates, check the cord’s low-temp flexibility. Some remain soft even at -58°F.
6. Plug Design
Strain-relief plugs, hooks, or triple outlets can improve convenience and reduce wear.
FAQs
