What the numbers mean
- At 12,000 running watts on its best fuel, this unit covers most household circuits through an appropriately sized transfer switch; central air conditioning typically needs load management or a soft starter.
- Runs on gasoline, propane — expect lower output on propane (roughly 10%) and natural gas (roughly 20%) than on gasoline; the spec table shows the published per-fuel ratings.
- House hookup: pairs with a 50 A generator inlet ( 14-50 / CS6365) and a transfer switch or interlock installed by an electrician.

Frequently asked questions
What can the Westinghouse WGen12000DF run during an outage?
With 12,000 running watts on its best fuel, the Westinghouse WGen12000DF covers most household circuits through an appropriately sized transfer switch; central air conditioning typically needs load management or a soft starter. Add up your actual loads with a sizing worksheet — the bands here are rough guidance, not a load calculation.
What inlet does the Westinghouse WGen12000DF need to power a house?
A 50 A generator inlet (a 14-50 or CS6365 connection) wired to a transfer switch or interlock kit — an electrician's job that normally requires a permit. Never backfeed through a dryer or wall outlet.
