What is everyone using in the situation where your Main AC breaker/panel is greater than 10 ft from the shore power
inlet? For reference:
ABYC E-188.8.131.52.1.3: If the location of the main shore power
disconnect circuit breaker is in excess of 10 feet (three meters) from the shore power inlet or the electrical
attachment point of a permanently installed shore power cord, additional fuses
or circuit breakers shall be provided within 10 feet (three meters) of the inlet or attachment point to the electrical system
of the boat
. Measurement is made along the conductors.
I had used a double pole, single
switch breaker in a supposedly waterproof housing from Paneltronics:
Paneltronics :: Waterproof Main Disconnect
However, to make a dramatic story short I had a very slow leak from my cockpit shower
line drip onto the disconnect assembly, water
slowly worked its way in, caused a short, and caused a shitstorm. Fortunately I was on board to quickly isolate the electrical
before a full on fire took place, but the disconnect assembly is completely melted. Amazingly and of great concern, the f- ing breaker didn't trip!
The Airpax breaker that came with the assembly is an internally coupled double pole breaker with one switch. The side without a switch was the side that had a burn-through. I'm no electrical guru, but this seems fishy to me.
The first step of course is to re-route the poorly designed cockpit shower
lines so this can never happen again. Then, in light of all of the above I would love to source a double-pole, double-switch breaker in a quality housing suitable for installation
in a lazerette.
Any input is appreciated!
