Short answer

Context

People often need backup power during storms or outages, which can coincide with rain. They want to know if it's safe to use a generator outdoors when it's wet.

When it might be safe

• If the generator is specifically rated for wet conditions
• If it’s protected by a certified weather cover that maintains ventilation
• If placed under a hard, open-sided shelter far from windows and doors

When it is not safe

• Using a wet or water-exposed generator
• Operating a generator without ground fault protection

Possible risks

• Electrical shock or electrocution
• Short-circuit damage to the generator
• Increased risk of fire or malfunctions due to moisture

Safer alternatives
