Re: Stus-List Triple Pole Breaker.

[Della Barba, Joe via CnC-List]

Back in the day some boats used 3 pole breakers on the shore power inlet to 
include the green wire. This has a dangerous failure mode or two, so it should 
no longer be done.

Subject: Stus-List Triple Pole Breaker.

A friend of mine is replacing a triple pole breaker on his older boat.

I know double pole breakers are used to cut out the Neutral and the Hot at the 
same time. This one also has a built-in reverse polarity breaker.
Boes anyone know how is it supposed to be wired ? is the third pole used to 
disconnect the ground ?

Thank You

I don't know very much about such things, but it sounds like if he is
replacing it anyway and in fact has a 120 volt system, he might want to
consider going with a double pole breaker instead of triple.

That is what I thought too. I did not think it was wise to disconnect the
green.
Thank you, I will let him know

Ahmet — a three-pole breaker like that would typically be used on a 240-volt 
shore power system, which has TWO hots and a neutral.  The breaker would 
interrupt all three of those, with the ground left untouched.  NEVER DISCONNECT 
THE SAFETY GROUND!!!

If your friend only has a 120-volt system, he only needs to wire two of the 
three poles.
