What Size Generator for Electric Dryer? (Startup vs. Running Watts)

An electric dryer is one of the largest residential loads you can attempt to run on a generator. The heating element alone draws 4,000–5,000W continuously, and the drum motor adds another 400–600W running — totaling 5,500W of combined continuous draw. The motor startup surge briefly pushes this to 6,500–7,000W. To handle this comfortably, you need a 7,500W+ generator with a 240V L14-30 outlet.

The 240V requirement is non-negotiable and is frequently overlooked by buyers: virtually every electric dryer in North America runs on 240V, 30A service. Your generator must have an L14-30 twist-lock outlet to connect via a transfer switch or properly rated cord. Most generators under 5,000W are 120V-only and simply cannot power an electric dryer regardless of wattage.

Here's the expert recommendation many homeowners don't want to hear: if you're buying a generator primarily for emergency outages, seriously consider switching to a gas dryer. A gas dryer uses natural gas or propane for heating and only needs 300–400W of electricity for the drum motor and controls — a load easily handled by a 1,000W inverter. The gas supply typically remains unaffected by power outages, meaning your laundry capability survives the outage with minimal generator load.

If you must run an electric dryer, use it exclusively — don't try to power other appliances simultaneously. Run the dryer in short cycles to manage fuel consumption, and ensure your generator has electric start (a 7,500W generator under full load is difficult to start manually if it stalls mid-cycle).
