Transfer switch
I might be a little late but I kind of just had the humming issue.
I reset the breaker at the pole for 20 seconds and the humming went silent.
This humming started after turning off the breaker at the post, firing up the generator to exercise it under load for 20 minutes, shutting down the gen then turning back on the power at the pole. I am assuming since I have not exercised my transfer switch that it “might” of got hung up even though I had full power. Maybe maybe not but it worked.
Hope this helps.
