Lloyd...

Absolutely not... Ground is for ground.... the emergency path to not glowing when things go awry.... or making the water tingly.... Not for manufaturing a "neutral" for 120... (although I to get creative in my land based circuitry sometimes)

All my 120 needs are converted from the 240 at the application...

MD, you are not out of the woods yet.

You have created a suicide cord set.

I sure hope none takes your 50 amp service plug and cord set, that you created, and then plugs it into a US wired 30 amp 120 boat-side.

As now the boat-side Line 1 will be at 120v, and so will the boat-side earth be at 120v, 180 degrees apart.

Big Bang Theory=unhappy sailor.

Also marina management, as it will most likely blow some transformers, and the voltage spikes across many of the neighbors boats is going to cost you also some big dollars.

I've got a wonky workaround that I'm doing for the time being... I hesitate to share as the electron heads like to pounce on bad ideas... BUT... They're all great guys, and wanna help...

I've got a standard 30A boat side to my cord/socket, and a 50A 120/240 male plugged into a 50A 120/240 service... Not all are dual voltage, so do some research... Anyway... There are two hot leads in this plus a neutral and ground... I've got the 2 hot and ground wired to the boat...
The 30A cord is plenty cause at 240, we're halving our current load...

...

Oh well...

Prediction realized...

The distribution breakers will power outlets...I will put one at the nav station or near, one in the main cabin and one in the galley. as near the running water as possible.

I think the small simple 120 panel and separate AC system is the hot ticket... (pun intended)

Lloyd,

I like to drive REALLY fast too!!!!!!!!

Just to ease your mind... I will label the cord end with the note:

"Do not use unless you want to fry all of your electronics, test marina fire extinguishers, AND... scoop net all of the dead fish"
