Frequently Asked Questions
Can I use an outdoor extension cord in rain?
Use only cords labeled for outdoor use (SJTW or similar) and keep connectors elevated and off standing water. These cords are weather-resistant but not waterproof; avoid submerging plugs or using damaged cords in wet conditions.
How do I know what gauge I need?
Match gauge to the amperage of devices. Use 12 AWG (12/3) for 15A loads and heavy tools, 14 AWG for medium loads if rated, and 16 AWG for lights and small appliances. Check the cord’s amp/watt rating and avoid exceeding it.
Is a lighted end worth it?
Yes — a lighted connector quickly shows when power is present, which is helpful for troubleshooting and busy outdoor setups. It doesn’t affect load capacity but improves convenience.
