Safety first

The U.S. Consumer Product Safety Commission says to never run a portable generator inside a home, garage, basement, crawlspace, or shed, to keep it outside and away from windows, doors, and vents, and to keep a working carbon monoxide alarm in the house (CPSC). Connecting a generator to house wiring needs a transfer switch or interlock installed to code; ask a licensed electrician.
