I've been on 30A 120V power at the dock for years and would now
like
to upgrade
to 50A 220V, or what they refer to as 50A 250V at the marina
office. I
haven't
put a meter on it yet but so far suspect it's closer to 220 than
250.
The socket
on the pedestal is like the one pictured he

They say it's 3-pole 4-wire. I'm guessing X and Y are the two hot
legs
and W is
the neutral. Between X or Y and W would be 120V+/- and between X
and Y
is the
220/250V. Right? How does the ground tie into it though? With
only 3
poles do we
run a separate wire from the boat to the pedestal, and if so how
do we
tie in?

Also can anyone suggest the cheapest place to get a plug like
that? So
far the
best price I've found is $68.18 he

Thank you for any help!

The plug is 10-20 bucks at home depot or lowes, Scottys whatever you
have. It's a dryer plug basically... As to the wiring, I forget
but I
have a book I always use when I do the wiring.. It was about 20
bucks at
home depot, I have had it for as long as I have owned a house...


Yikes! It's NOT a dryer plug, basically or otherwise.



Not to knock Scotty but I got a big kick out of his statement, "As to
the wiring, I forget but I have a book I always use when I do the
wiring".

I think Scott should limit his wiring to 12 volt devices. Whoops. I
take that back. My oldest grandson recently got his first car and
(like all teenagers) was installing a sound system that included a
massive bass speaker cabinet and a dedicated, 1200 watt amplifier to
drive it. He was wiring the power to the amp with some small gauge
"hook up" wire that he bought. I explained to him that he only
had 12
volts +/- available and if the amp was capable of 1200 watts, he
could
be drawing close to 100 peak amps at times and his little hookup wire
was going to act like a fuse. Got him some appropriately sized wire.



I'm not a fan of taking unnecessary physical, fire or explosion risks,
so I don't do wiring any more difficult than replacing a switch or a
light fixture. We haven't really had any serious electrical issues
here. The wiring for our generator was handled by the contractor's
licensed electricians.

Thank you for your invaluable input.


I think the whole idea was to "knock" me.. it's always good though
cause I just shut off rec.boats for a day and it goes away Of course
another lib gets to "bully" another opinion off the table, but so be
it.. Anyway, my point was "I use a book whenever I do this stuff" even
the stuff I know well like plumbing, etc.

Anyway, I went and looked at my book and realized that the hookup the
guy was asking about was above my pay grade so of course I wouldn't
have taken it on, even with my book...

Hey, I know I'm no expert but I do maintain a 100 year old house and
from water delivery, septic, plumbing, heat, electrical, paint,
structure... I do manage to get it all done, by myself, me and my
stupid books.. And when I need a hole dug, I hire a pro with bigger
tools other than that, I get by.

My comment was sarcastic.
