Running a generator in wet weather is safe when you use the right cover for the job. A generator cover while running must be a purpose-built running cover or safety canopy – not a standard storage cover, tarp, or fitted dust cover.
Products like the GenTent safety canopy and DuroMax running covers are specifically engineered to allow heat and exhaust gases to escape while keeping rain, snow, and wind off the unit. Standard storage covers seal too tightly around the generator, block airflow, trap heat, and create a serious fire and carbon monoxide hazard.
