Can you run a generator in the rain?
Not without protection. Wet conditions create a shock hazard and can ruin the generator — but the fix is never to bring it indoors.
The hazard
Water reaching the outlets or internals risks electrocution and damage. But the dangerous "solution" people reach for — moving it into a garage, shed, or porch — is far worse, because it traps carbon monoxide. CO from a generator can be lethal within minutes in an enclosed space, even with the door open.
The right way
- Use an open, ventilated generator tent or canopy rated for running units.
- Keep it outdoors, at least 20 feet from the house, exhaust pointed away.
- Set it on a dry, stable, non-flammable surface above pooling water.
Common questions
Can you run a generator in the rain?
Not unprotected. Water can cause electrocution and damage the generator. Use it under an open, ventilated generator cover or canopy rated for the purpose — never enclosed, and never indoors or in a garage.
How far should a generator be from the house?
At least 20 feet, with exhaust pointed away from doors, windows, and vents — per CPSC and CDC guidance — because of carbon monoxide.
