12 Gauge Extension Cords

12 GAUGE EXTENSION CORDS

This category covers our selection of 12-gauge extension cords featuring male to female Nema 5-15P to Nema 5-15 R or and Nema 6-20P to Nema 6-20R connectors at either end.

The essential extension cord

12-gauge extension cords are used for most tools and high power appliances. A 12 gauge extension cord rated at 20 amps is a versatile extension for both indoor and outdoor use. Over 100-feet, it can safely handle 16 amps. It lets you run a single high-wattage power tool or two to three smaller tools or appliances.

Forever versatile 12 gauge extension cords

A household will typically have more than one 12 gauge extension cord. While those who maintain a sizeable tool collection often like keeping an extension for each item of hardware. A 100 ft 12 gauge extension cord is perfect for things like table saws, radial saws, powerful orbital sanders, compressors, and welding equipment. Anything that requires a mains outlet but is typically used outdoors or in a garage/workshop environment will be an ideal match to a 12 gauge.

NEMA L5-20P to NEMA L5-20R

Keep in mind that you should use each type of cord in the area that it’s best suited. If you’re going to be working outdoors on a construction site, you need a heavy-duty duty outdoor cord. Our Nema L5-20P to NEMA L5-20R heavy-duty extension cord is the perfect choice for anyone that will be working outside. Go for an indoor/outdoor combination cable if you know that you’ll be switching between your work area and using it outside of your workshop.

Flat extension cables

If you’re running an extension inside, then you need a flat cable to keep everything tidy and your cable out of the way. Consider a flat cable with a flat cord power strip for areas where you’ll be using a lot of small appliances. You can use one 12 gauge flat extension cord with a power strip to run both your high-end tools on their own. To power two to three of your more general implements like drills, electric screwdrivers, soldering irons, and anything that typically pulls a low amperage.

12 Gauge extension cord over the distance

Don't forget that a 12 gauge extension is also perfect for powering general appliances like computers and televisions over a long distance. This is ideal for running a lead from a generator outside, letting you take full advantage of the 100-foot length. With the voltage drop taken into consideration, a 100-foot 12 gauge medium-duty cord gives you enough power to run anything under 10 amps which makes it the best for general electronics.
