Aware of all this - I operate one or two submarine cable landing stations...

What I mean by "pre-wired" is that, perhaps, the generator is pre-setup 
and wired into the house, but is not in standby mode to manage costs, 
and perhaps, to be reliable since ATS's are often dodgy.

Maybe a manual start is required. Maybe a changeover switch has to be 
flipped. That sort of thing.

Of course, we are speculating, and Sabri can answer best.
