I've been on 30A 120V power at the dock for years and would now like

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...

Not true at all, sorry.

This is a non-NEMA twist lock 50a plug, that is corrosion resistant.

A dryer plug is a NEMA 14-30 straight blade that would go south pretty
quickly on a pier.



Yup. I think Scotty should stick to building websites and not wiring
boats.



Why, cause I took a quick look and made a mistake? I have done a lot of
wiring in my time including my whole house to code in Essex from moving
in with full Knob and Tube... I have done barns, and wells. When you
have a 100 year old house you tend to pick up stuff. You should see me
sweat a pipe.... even if I don't know all the right terminology. Either
way, that's why I always keep my electrical book with me to check my own
work as I go....

Scott, just my 2 cents worth, but when a guy is asking for advice on a
potentially critical/high powered electrical issue, I think it
deserves more than a quick look.
