Safety first

Run a generator outdoors only, at least 20 feet from the house, with the exhaust pointed away from doors, windows and vents. Never in a garage, basement, shed or crawlspace, even with the door open.
Carbon monoxide is odorless and can kill in minutes. Keep battery CO alarms working inside the home.
Never backfeed a house by plugging a generator into a wall outlet or dryer receptacle. It can energize utility lines and kill a lineworker or a neighbor.
Connecting to home wiring requires a transfer switch or a listed breaker interlock with a power inlet box, installed by a licensed electrician and permitted where your jurisdiction requires it.
