Q: Can I plug a generator or power station into a wall outlet to power my house?

No. Powering house wiring by plugging a generator into a wall outlet, called backfeeding, is extremely dangerous: the CPSC says it can electrocute utility workers and neighbors served by the same transformer, and it bypasses your home's built-in circuit protection. OSHA says a generator should only be connected to a building's wiring through a transfer switch installed by a qualified electrician. Otherwise, plug appliances straight into the unit.

Home wiring is a job for a licensed electrician. New circuits, outlets, transfer switches and battery connections must meet the National Electrical Code and your local rules, and many need a permit and inspection.

OSHA warns that a generator attached to a building without a properly installed transfer switch can energize wiring for great distances. Some larger power stations are built to connect to home circuits through the maker's own panel: EcoFlow, for example, says its DELTA Pro Ultra needs its Smart Home Panel 2, installed by an electrician.
