What Size Generator Do You Need to Run a Electric Clothes Dryer (240V)?
To safely power a Electric Clothes Dryer (240V) during a blackout without tripping breakers or damaging the motor, you need a generator rated for at least:
Why Inrush Current (Starting Watts) Matters for Electric Clothes Dryer (240V)
Combines a 3500W-4500W heating coil with a 500W-1000W electric motor that spins the drum.
Many portable generators are marketed by their surge wattage rather than their continuous rating. For instance, a "2200W generator" typically provides 1,800 running watts and only delivers 2,200W for a split second. Always ensure your generator satisfies both the continuous and peak surge requirements of your setup.
A standard 120V portable generator cannot power this appliance. You must use a dual-voltage generator with a 240V NEMA L14-30 receptacle and connect it through a certified transfer switch or generator interlock kit.

Recommended Extension Cord Wire Gauge (AWG)
Running an appliance on an undersized (thin) extension cord causes severe voltage drop, overheating the generator and potentially burning out the appliance motor.
| Cord Length | Amps Drawn (16.7A) | Minimum Wire Gauge | Safety Rating |
|---|---|---|---|
| Up to 25 ft | 16.7 Amps | 14 AWG | Safe |
| 25 to 50 ft | 16.7 Amps | 12 AWG (Heavy Duty) | Recommended |
| 50 to 100 ft | 16.7 Amps | 10 AWG (Extra Heavy Duty) | Essential to prevent voltage drop |
