My 1996 400db had line 1 shore power converted to 240v for Australia before I bought it. I have figured out just about everything as to how it works, a sweet combination of the original 110v generator and 110v appliances , as well as 240v sockets and a hunk of an isolating transformer that can pass through 240v and convert to 110v and 110v to 240v. Everything Works (despite the hertz), line 1 and 2 all fire up on the panel with the Australian line 1 inlet.

My question is why do I have a 220v 50 cycle 16a shore inlet on line 2. I had assumed it was redundant but then noticed it was labelled 220v 50 cycles which confused me, as the boat came from a Florida owner back in the day. so I would have expected originally there would be two 110v 60 hertz line inputs.
