5 Things to Know About Extension Cord Gauge for a 15-Amp Tool at 50 Feet

Use 12-gauge wire for any 15-amp tool run longer than 25 feet. At 50 feet, resistance adds up, and 14-gauge risks voltage drop, motor damage, or a tripped breaker.

A too-thin cord makes the motor run hot. The tool will still spin, but it pulls extra current to compensate, which burns up tools faster.

14-gauge might barely work at 50 feet, but it is not worth the gamble. The small savings are not worth replacing a damaged tool.

For runs under 25 feet, 14-gauge is fine. But most shop tools are 15 amps, and 50 feet is common, so just buy the 12-gauge cord.

Do not save twelve bucks on an extension cord. The cost of a new tool far exceeds the price difference.
