I'm upgrading to 240v....though its entirely possible the boat was 240v in the past as the wiring is 4 wire 240v type coming in, plugs are, etc. But....the current main panel was set up for only 120v.
I have a 2 pole manual power transfer switch on the boat that is 3 position. Gen/Off/Shore. Searching the internet turns up mostly home generator/service info.......and there is argument there over whether the transfer switch can be 2 pole interrupting the hot wires with shared neutral in the panel bus........or whether the neutral also has to be switched. Apparently it depends on code and whether your generator is portable, or over a certain KW output.
Obviously switching to a 3 pole switch could add another $500 plus dollars.
I don't even have a generator on board yet, as the previous owner took it off the boat before it was repo-ed, but...can anyone tell me what is correct in a marine application? Can the 2 hot wires be switched but the neutral shared in the panel?
Thanks
