Yep.... It hums...
Just got done installing the Progressive industries hardwired 30amp unit... luckily I installed it in the electrical bay. When I first plugged it in, it was silent. I went into the rv and turned on...
Forum Discussion
Someone on these forums said it is the "contactor" inside the unit that makes the humming sound. I will see if it bothers me on our next trip. I can usually sleep thru a war but I may do something like insulate the bay etc.. To cut down on the hum noise
