What should you keep in mind while running a portable generator in adverse weather?
First of all, you should not run your portable generator during a hurricane or strong wind. Since you have to place the generator on the outside and away from the home, you should not run it during this time.
On the other hand, moisture or water is the killer of the generator. It could damage your generator seriously. Most of the modern generator comes with advanced technology to handle moisture. If the water penetrates the generator engine, your generator will shut off.
So, you should run your generator only in mild wind or rain. Though these covers can handle up to 70 mp/h, which is incredible, you should not run your generator in such a condition.
