That's about the size that I'd buy when it comes time to replace my Suzuki 4400 watt unit. The 7200 watt unit would allow me to keep my well pump on with all the other stuff on my Y2K box, and my 4010 is big enough to drive it (at least 10 hp needed vs. 14 available on my PTO).
A good way to mount this is to buy a TSC carryall, bolt a pallet to the carryall and then bolt the generator to the pallet. Then buy or cut a PTO shaft to fit.
Mount the pallet on castors to make attaching the carryall/generator to the 3 ph easier.
I've a transfer switch in my Y2K box that turns the main power off and the generator power on at the same time. Actually, it's just 2 switches side by side with a metal thingie in between that rotates between the 2. Can't turn one on or off with the other going opposite.
However, I had to add one of the 110 circuits to my carriage house to the generator output. Have to turn off the breaker to the carriage house before turning on the switch to the that circuit on the carriage house on which my freezer runs. Off that same input box, I also wired another circuit and put in 2 plugs labeled "Gen" in the house to run our frig in the basement plus 2 computers.
The previous owner put in the Y2K box and didn't have a frig in the basement nor the carriage house.
