5 Things to Know About Extension Cord Gauge for Shop Tools
- 12-gauge handles 15 amps at 50 feet with a 3–4% voltage drop, which is safe for a table saw.
- 10-gauge drops only about 2% voltage, giving the motor more consistent full power.
- 10-gauge is overkill for most current setups but future-proofs you for a bigger saw or longer 100-foot runs.
- Both gauges are safe and won’t cause fire hazards in your shop.
- Choose 12-gauge for budget and adequacy; choose 10-gauge for a small performance edge and flexibility.
