AC Fuse Panel Location

Hey all
Doing a rewire of my AC electrical (no fuses)
Its a 30 amp system and Ive got a hot water heater, a small 10 amp battery charger and 4 plugs.
I just measured the distance from the AC Inlet to where I want the panel and its 12 ft. I want to make it AYBC compliant but have no other good spot for the panel (to keep it accessable). Moving the inlet means cutting another hole in my boat. Can I just up the wire size feeding the panel or is there something else I can do? Do I really need to worry about this?
Thanks
Gary

You just need a separate 30 amp fuse between the panel and the AC shorepower connection, within 6 feet of the shorepower connection. The inlet can stay where it is and the panel can be where you want it.

Just be sure to put it in a location that is fairly easy to reach, not one that you have to hang upside down, twist backwards and blindly feel around with your arm extended to maximum and needing just a bit of dumb luck to actually get to...

Yeah, that got redone

The concept is OK; but the details are not.

The ABYC standard calls for a separate double pole circuit breaker (not a fuse or set of fuses) rated for the shore power service if the distance, measured along the conductor from the inlet to the main AC panel board double pole circuit breaker is greater than 10 feet.

A Blue Sea Systems part nr. 8077 AC Main - PN 8077 - Blue Sea Systems is a good solution for this issue. Mount it in a utility box in a dry, accessible place and you are in compliance.

Hope this helps.
