Can a generator get rained on?

I understand the danger of running generator in the rain...but that's not my issue...

If we are camping, and have the generator with us but are not actually using it at the time (operating on shore power), does it cause direct harm for the generator to be exposed to rain? Is it necessary to keep it under cover from rain even when not in use?

This line of question came to my mind because I've had motorcycles for years...that have wires and metal parts exposed everywhere....that I ride in the rain...and there's no particular immediate harm that results...it starts, the panel still operates, etc., even in a downpour...and it doesn't immediately turn to rusty dust

Thanks for input
  • I always cover my generator when it isn't running and outside.
  • What does the owners manual say about it. Wind driven rain can get into some places, cause havoc and then you'll be wondering why things get rusty and don't work. A simple lawn chair cover with about 30 seconds of effort would alleviate that.
  • We just drape a tarp over it, and anchor the tarp with rocks. I'm not sure that rain would be harmful, but I don't want to take a chance.
  • As long as no water is going into the fuel or carburetor there is no immediate need to panic and jump up at 3am to bring it inside. Although a tarp would not hurt. Running it 20 minutes to dry it out before storage would not hurt either.
  • Not ideal but we've used ours in a little light sprinkles at times with no ill effects (at least it's 14yrs old and still runs fine).

    I would be more hesitant in a total downpour. Better if you could rig up a tarp or something to keep the worst of it off. Maybe put it under the truck tailgate with the exhaust facing away from both truck and trailer but at least keep most of the rain off it.
