5 Things to Know About Wire Gauge for a 2000-Watt Heater at 75 Feet

10-gauge wire is the right choice for a 2000-watt heater at 75 feet. It handles the load safely and minimizes voltage drop.

12-gauge wire will probably work, but it is not the correct choice. It may overheat or cause voltage drop issues over that distance.

Voltage drop increases with longer runs and thinner wire. At 75 feet, 12-gauge can drop enough voltage to reduce heater performance.

Always match wire gauge to the appliance’s amperage and distance. For a 2000-watt heater on a 120-volt circuit, that means 10-gauge.

Using undersized wire risks fire and equipment damage. Stick to 10-gauge for safety and reliability.
