50 feet is the max for a 16-gauge cord at 10 amps.

Yes, you can push to 100 feet in a pinch, but you’ll lose noticeable power and risk overheating the cord. Stick to 50 feet for reliable performance.

Voltage drop is the real problem here. At 10 amps on a 16-gauge cord, 50 feet drops about 2.5% — fine for most tools. Double that to 100 feet and you’re looking at a 5% drop, which can make motors run hotter and slower. Worse, if you coil that long cord up while running a heavy load, it can get dangerously hot.

Also, 16-gauge is rated for 13 amps max, but that’s for free air. Wrapped on a reel or buried under stuff? Derate it. A 10-amp tool is already close to 80% of the cord’s safe capacity, so don’t push distance or load.

If you need 100 feet, step up to 14-gauge. Future you will thank you.
