My question would be Did keystone mount the transfer switch in a manner AND orientation specified by progressive? The cover should show how it is to be mounted, I would think. The inside cover should show you which contacts are for incoming priority power, ie, park power and the wiring sequence for line one hot, neutral, and ground, line two hot, neutral, and ground as well as the connections for secondary power, ie, generator, and wiring output contacts to the breaker box. I do not have this transfer switch in my montana nor a gennie...but that is the switch I would use if/when I get around to mounting a power inlet on the side of my montana. Sorry for the lack of help.
