T&T: 208v vs. 240v Was: Re: Shore Power and Electricity Concepts (LONG POST - was "Power Cords")

Gil:

I think the poster might have the same set up I have on my 1979 43 foot 
Viking. This setup was common for a couple of years but you never see it on 
newer boats. I have two 50 AMP 120 Volt cords that are connected to the two 
different sides of the electrical panel. A/C and Heaters on Cord #2 and 
everything else on Cord #1. There is a switch to run the whole boat on Cord 
#1 but obviously you only have 50 Amps instead of 100 Amps. Everything on 
the boat is 120 volt always.

I do have a splitter so I can plug both cords into a single 50 Amp 240 volt 
outlet.

I plan on converting this setup to one modern 50 Amp 240 volt cord this winter.
