I mounted mine in the compartment with the shore power cable and generator outlet and used the Hughes installation kit. That way, it's easy to reconfigure. I can disconnect it, or leave it permanently connected if I want to.
One good reason to do it that way, is sometimes the relay contacts in the autoformer get stuck together while boosting.
Then, when pedestal power returns to normal, the voltage out of the Hughes will be too high.
That happened to me last trip.I just took the Hughes unit out of the circuit until I could fix it.
