Hello Bob,

It is almost that simple. It is somewhat different from installing a
branch circuit in your house, though.

The green shore power wire should be connected to the boat's underwater
ground system (which is generally the boat's DC ground system) per the
ABYC.

Doing so can raise other issues: it could provide a path for galvanic
currents that erode your prop, etc. A galvanic isolator could prevent
such currents, but depending on where you dock, may not be necessary.

Not doing so raises other issues involving safety. I would stick with
the ABYC standards for AC and DC wiring.

I think if you search the web, you'll find plenty of detailed
information on what you want to do. If you have specific questions,
we'll try to answer them for you.

Good luck.

Chuck

I want to add a simple shore power hook-up.
I know I'll need a through the wall cover and plug recptical that is wired
to a breaker. From the breaker I would guess to a std GFI plug-in for
running heaters or small appliances? And if I want to hook up an automatic
battery chage from the breaker to the charger.

Is it that simple or do I have to run any special grounding. If so please
explain the grounding in detail. I've heard there may be special grounding
but do not understand what the special grounding is about or what and where
it grounds to. I figured that the grounding would come from the shore power
circuit on the dock.
