Drenching, Running and Powering a Protected Generator
never to run your generator in an enclosed environment. There are two concerns. First, the generator must have fresh air to run. It cannot run on its own exhaust gases. Second, the generator relies on an open environment to stay cool. An overheated generator engine will not last as long, can seize up, and depending on the heat level, can cause an even more dangerous situation.
Generator manufacturers warn against use in wet weather specifically due to risk of electrocution (which we know to be the electrical panel and outlets). They do not state a risk of equipment failure. So the question remains, will the generator be ok if parts of it get wet? According to several generator installation experts, beyond the electrical panel and outlets, the remainder of the generator can get wet without posing danger or damage. We thought it best to put this to test.
This video shows a portable generator being drenched, while protected by the GenTent, and powering a sawzall electric saw. Water is purposely directed to the engine, battery and genset (the long cylinder piece that actually generates electricity) and shows that its performance is unaffected by direct and continuous water. The electrical outlets remain dry thoughout this test.
Disclaimer: What you are about to see was done under careful conditions. Handling electricity and water at the same time is not recommended, therefore please do not try this at home. Even under these conditions, the person in the video forgot to wipe his hands dry after working the hose. GenTent Safety Canopies claims that its GenTent keeps water away from the electrical outlets which allows the generator to be used safely in wet weather conditions. No other GenTent Safety Canopies claims should be taken from this video.
