Running a generator outdoors during harsh weather—whether it’s heavy rain, snow, or strong winds—poses real risks not only to the unit’s performance but also to your safety. While portable generators are designed for outdoor use, they must be properly shielded from the elements to ensure safe and continuous operation. That’s where generator running covers come in.
A generator running cover is more than a rain tarp—it’s a purpose-built shelter that allows your generator to run safely in extreme weather. These covers are engineered with fire-retardant materials, ventilation systems, and frame supports that keep your generator cool, dry, and operational. Without one, you risk water entering critical components, resulting in electrocution hazards, equipment failure, or shortened generator lifespan.
