Shore power breaker

[Grub54891]

Hi, been looking to install a 30 amp breaker on my shore power line. Would like to put it in a weather resistant box in the cockpit area,just after the shore power inlet.I cant seem to find one that looks good,easily opened quality built. Any suggestions? Thanks in advance!

Re: Shore power breaker

Isn't your shore power already on a breaker? If so why put another one on?

Re: Shore power breaker

Abyc requires a breaker within 3 feet of shore power inlet. Yes there is a breaker in the main panel, but 10 feet away. Just want to make shure all wiring on the boat is compliant!

Can you post a link? There are numerous boats on the water and in marinas and I'll bet i can't find one with a breaker within 3 ft of inlet. I yet have to see a A/C breaker of any sort on a boat other then what is in the main panel and they aren't breakers. Just on and off switches. I think you might have misread the code. I think it's ten ft (3meters).ABYC conformance isn't a requirement but a guideline of technical standards
Is your main panel within 10ft of the shore power hookup on your boat? If so you don't need anything to be compliant.AC panel can be a single pole breaker IF the panel has a reverse polarity indicator

Re: Shore power breaker

Most don't have the breaker,I forget the year it changed,new boat construction requires the breaker.I'll re-read the requirement's on placement. This one is grandfathered in before the requirements changed but, if repairing, do it right I say.

Don't confuse DC with AC wiring.

Your shore power box on the dock has to have a 30A breaker before the receptical.
On the boat you have a the receptical where you plug your shore power cord in, then you have to go to a panel to the AC main breaker, and as I recall, it has to break all 3 legs, hot, neutral, ground. From there you go to your branch circuits.
Don't recall the actual distance between the receptical and main breaker, but I know it's more than 3 feet.

Re: Shore power breaker

Nope,not confusing ac/dc systems. Mabe just overthinking my memory a bit. I'm looking for the standards again online now. We have the abyc book at work,I'll have to look at that again.

Remember ABCY is not a required procedure. It's only a recommendation. I think you are referring to the new standards. It's called a ELCI.(isolation transformer) There similar to GFCI's and not to be confused with galvanic isolators.See ABYC E-11.13.3.5 and ABYC E-11.11.1.
Surface Mount System With ELCI Main installed within 10 ft. of shore power AC inlet shore power cord
Blue Seas has them

Here found this for you.

i don't have the book at home but im sure that you are not allowed a breaker in a ground wire period.

a on-board generator transfer switch has rules that concern disconnecting it from the shore cable but thats a switch not a breaker

Re: Shore power breaker

Glenn, That transfer switch may be what I was thinking about instead of the breaker. Not sure any more. Been away from boats with shore power too long.
