Surge Protector - Hardwired without transfer switch?

Nothing needed for your scenario, with our TH we either plugged directly into shorepower with our surge protector or plugged power cord into dedicated generator outlet provided on our rig. With our class A nothing has changed for the most part, we plug power cord with surge protector into power pedestal, transfer switch always prioritizes Onan power when genny is running anyway. We love our Hughes SP, works flawlessly and the info provided via bluetooth is quite in depth.
