What gauge extension cord should I use for a table saw at 50 feet and 100 feet?

Use 10-gauge at 50 feet and 8-gauge at 100 feet. Table saws have high startup surge that can pull double the running amps, and undersized cords cause voltage drop, killing torque and overheating the motor. At 100 feet, 10-gauge is borderline; 8-gauge keeps the saw happy and prevents random breaker trips. Don’t trust cheap 14-gauge cords rated for 15 amps—go one size up from the chart.
