Look for a generator whose running (rated) watts are at least the first number and whose starting (surge or peak) watts are at least the second. This assumes motors start one at a time, so switch on the refrigerator, pumps and furnace fan one after another rather than all at once.
Run a portable generator outdoors only, at least 20 feet from doors, windows and vents, and never plug it into a wall outlet to power the house. A transfer switch installed by an electrician is the safe way to connect it to home wiring.
