Smaller boats without shore power
connectors usually carry an adapter which converts a 30 amp twist lock
plug into a conventional 15 amp socket. You could do the same thing
with a 50 amp plug just using one leg of the 240.



There's an interesting discussion that needs to be aired out.......

The breaker on the 50A outlet on the dock is 50A. I'm not sure how much
surge it will produce before it trips, but it's a thermal breaker, not
magnetic, so it takes time to heat up and trip on a short.

So, here comes Joe Boater with his "adapter". Joe plugs his adapter into
the massive 50A jack, then plugs his #12 30A boat cord into the adapter.
You've all seen it and thought nothing of it.

Now, if this were in a building, it would be called a "violation of the
National Electrical Code" because the 50 amp branch circuit was
"adapted" to a way-too-small-for-50-amp cable leading to the fire in the
boat. If the cable shorts, because someone pinched it in a hatch for
instance, the cable will explode in flames all the way back to the
adapter. This will set the flammable plastic boat and wooden dock on
fire, just because the marina did not provide the PROPER circuit for Joe
Boater's 30A (or worse less) circuit.

There are lots of "splitters", even provided by the marina staff!, to
plug your 20 or 30A boat into this 50A branch circuit.....still a
violation as far as I am concerned.

And you're gonna SLEEP in there?!

Why bother to put breakers on the dock at all??
