PD 52 transfer switch hum normal?
My pd52 hums pretty loud. How loud is too loud? Wrap in insulation?

UPDATE: Thank you for your responses. I bought and am having installed the new PD52DCS at camping world next week. Note: They had a sale on the unit, plus $25 off on President's day, plus $59 this month to install anything. Seemingly a good deal.
