5 Things to Know About Extension Cord Gauge for a 15-Amp Miter Saw

Use 12 AWG as the minimum for a 15-amp miter saw at 50 feet. Thinner 14-gauge cord will heat up and drop voltage, risking damage to the saw over time.

A 15-amp miter saw draws near the full circuit rating, and electric motors have a high startup surge. This makes voltage drop a real concern at 50 feet.

10 AWG is better if you can find it without spending a fortune. The price difference isn’t huge, and you’ll never regret having a heavier cord for extra safety and less voltage drop.

14-gauge cord will work briefly but will get noticeably warm with a big miter saw. It can trip breakers or damage the saw over time.

Don’t cheap out on extension cords for power tools. Stick to 12 AWG for anything near 15 amps at 50 feet.
