Use the load calculator to total your own appliances.
Fuel and runtime
The maker states a 11.9-gallon tank and up to 15 hours at the stated load, which implies about 0.79 gallons per hour at that load.
Multi-fuel units usually produce less power on propane or natural gas than on gasoline; the maker's per-fuel ratings are the ones to size against.
Connecting it to a home
To power home circuits you need a rated transfer switch or interlock and an inlet, matched to this generator's outlet and amperage, installed by a licensed electrician.
Check the pairing in the generator ↔ transfer-switch compatibility matrix.
Safety and placement
This listing mentions a carbon monoxide shutoff or sensor, which is a useful backup — not a substitute for placing the generator outdoors and keeping working CO alarms inside.
