Which is better 12 gauge or 14 gauge extension cord?

14-Gauge Cords: Any 14-gauge cord between 0 and 50 feet long will adequately handle loads between 10 and 15 amps. 12-Gauge Cords: If your tool load is between 10 and 15 amps and the length of the cord is 50 to 100 feet, you need a 12-gauge cord to safely power any tool. This is a great extension cord for many purposes.

Are orange extension cords for outdoor use?

W indicates a cord designed for outdoor use. The biggest difference between indoor and outdoor extension cords is the insulation. Outdoor versions have bright orange rubber, plastic, or vinyl covers, while indoor cords are much less heavy-duty. J means the cord has standard 300-volt insulation.

How much can you plug into an extension cord?

As the cord gets longer, the current carrying capacity of the cord gets lower. For example, a 16 gauge extension cord less than 50 feet in length can power a 1625 watt (W) appliance. A 16 gauge cord that is longer than 50 feet in length can only power an appliance up to 1250W.
