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

Jim, you must have a very large boat to have two 50A shore power connections.
Is your 50A power 110VAC or 220VAC?  That will tell you how many power legs of
110VAC you have.  If it's 220VAC, then you have 100A of 120VAC service.  Like
I said, you must have a very large boat.
2. If your splitter has two 30A
connections on the shore going to one of your 50A cables, you should have 60A
of total capacity.
3. This sounds like you're suggesting you have an adapter
and not a splitter.
Typically, a 50A cable is 220VAC (two legs of 110VAC).
Typically, a 50A shore connector is 220VAC.
Typically, a splitter will adapt
one 50A 220VAC cable to two 30A 110VAC shore connections (reduced from 50 A
per leg to 30A per leg)
Typically, an adapter will connect one 50A 220VAC
cable to one 30A 110VAC shore power connections.  This significantly reduces
available current to just 30A and does not support any 220VAC systems you may
have.
This should really confuse things :-)

All
Sorry to add to this
already confusing (at least to me) subject but I have a
situation that I have
received at least a dozen different answers to and I'm
not sure which, if any,
is correct.

When I purchased Lark it came with two 50A cables and a 50A
splitter that
hooked to a 50A shore power source.  Each of the 50A cables
attach to a
separate receptacle on the boat.  I have been told the
following...

1.  Due to the splitter I have 50A on each leg
2.  Due to the
splitter I only have 25A on each leg and would be better off
buying 2 30A
cables so I would have 30A on each leg
3.  I could eliminate the splitter and
go with one 50A cable and still have
50A as both legs share one incoming
source (now I am really confused at this
point)

Hopefully I have supplied
sufficient background to receive an answer that is
correct and that I could
understand.

   Thanks for any assistance
