Morgan,

While in a perfect world you may be right.

A boat isn't a perfect world , any number of situations, could put a life at risk....by assuming the neutral carries no volt/amps.

So if any is reading this topic, assume the the N has just as much V/A's as the hot leg.

That being said, I am assuming that the black (hot) wire goes to the copper buss bar. White (neutral) goes to #2 breaker and the ground ties common to all device grounds. Is this right?

You have what many of us call a SeaRay Breaker, it is not a three pole 220 breaker. It is also common with an M & I Panel 120v Entrance.

# 1 is not a breaker, it's a coil

#2 is Ac 120 Neutral Breaker

# 3 is Ac 120 Hot(line one) Breaker

# 1 is a Coil to alert for reverse polarity

# 2 is a CI on the N to trip # 3

# 3 is a CI to trip on OC, and SC to Grnd(either by N, or G)...

Most excellent. I didn't think of #1 as a coil. I was pretty sure it's purpose was to have something to do with the reverse polarity. Regardless the wiring result will be the same...Black from shore power to copper buss which feeds #3 left side of breaker. White from shore power to #2 left side of breaker. A white runner from right side of #2 to a neutral buss...and all grounds to another buss. I agree that the neutral buss should be regarded as lethal on a boat in case of a hot to neutral switch. It's not unheard of.

Re: Calling all AC Guru's

I'll give it a try maybe tomorrow. If by chance I stop posting on CF, you'll know what happened...
