Relocating shorepower 12 ft. is additional breaker required ?

[daddy d]

I am relocating the shore power on a 1989 390ec. adding a 12ft length to the current 10 ft length Is an aditional main circuit requireed located next to the shore power inlet? I know all new boats require a breaker, ABYC , seems redundant, the marina has 30amp circuit protection to the boat, why would an additional breaker add any more protection then the orginal OEM install. I will route the semi ridgid conduit behind the cockkpit side panels a anchor it every 3 ft. Its not going any where.

daddy d, A little in the dark about what you are trying to do .You already have a 30amp breaker at your boat panel.To relocate shore power boat inlet you need to run new 10 Gauge, 4 Conductor (10/4) 600V SOOW wire from new location of boat inlet to boat panel.

The breaker protects the circuit between the shore power inlet and the main AC panel. The breaker is a double breaker in that both the hot and neutral are switched and on a breaker. This protects the boat from potential reversed polarity damage. Reversed polarity is something the dock power point breaker will not correct.

From your other post I thought you were going to run an all new line from the the new inlet to the AC panel. It sounds like you are back to having a mechanical splice between the new cable and the old. If you are going that route I would definitely suggest adding a breaker at the inlet.

Four conductor?
Black - hot
white - neutral
green - ground

What's the fourth? Also according to my wiring diagrams the AC system is 10/3 cable for 110 volt installations.

Henry, you are correct it is 10/3

I will install all new one length cable 10/3 (2) 30 amp 120vac services using the current main breakers located on the main distribution panel. rather than run shore power cables on the outside of the boat they will be on the inside.

 

[daddy d]

correct 10/3 triplex (2) circuits running new one length cable from the inlet to the main dist panel breakers

If you look at where the power outlet is located on most boats it's adjacent to the panel, short run to the C/B, if it is any distance from the panlel there is another C/B or fuse where it comes into the boat. It's there to protect that section of cable that runs through the boat.
