ABYC E11.10.1.1.2
« on: December 27, 2016, 04:09:14 PM »
Had the boat surveyed for going south
Cited was ABYC E11.10.1.1.2; referring to ungrounded conductors needing an in line fuse
The solar panels and the solar controllers/chargers are both grounded to the negative bus bar
What do you think about this??????????? ???  :o

Anyways, any Ideas as to what the violation is? Sorry these controllers and charger belong to a good friend and sent me this message. The controllers are morningstar mppt 30, but no idea on the charger . Three AGM 8D batteries, Three morningstar MPPT30 controllers and Three Alt Energy 200 watt 24 volt panels. So it is one panel and one controller and one battery to a system! System one is the start, the second is the house and the third is the windless. any thoughts here?


I forgot to add the solar panels go to a 12A circuit breaker then to the solar controller which goes to a 30A circuit breaker then on to the battery
Seems redundant to add an in line fuse, of the same amperage I would suspect
In addition the circuit breakers are in plain sight

Are you sure that reference is correct? Here is what I found reference E11.10.1.1.2. Do you know if this was in the AC or DC system?

Also "Ungrounded Conductor" in layman's terms is the hot conductor.

hi john, thank you! the violation is on the DC as I understand it as this boat only has dc hard wired and a portable genset running in the cockpit if the batteries get low due to bad weather. I just added some added info to the original post that was passed onto me.

Just for clarification "Ungrounded Conductor" in layman's terms is the hot conductor.

Without knowing exactly what section was cited it is hard to tell what the inspector was looking at. There are requirement that the overcurrent devices be as close to the power source (Batteries) and not to exceed a given distance. (see below). Because of this I have an ANL fuse at the battery just after my Battery Switch before the CB that is located beside the Classic that is mounted in a MD Quad box along with the PV Breaker. Then each panel string has its own breaker in the combiner box located near the solar panels.

11.12.1. FOR DC SYSTEMS
11.12.1.1. Battery Charging Sources
11.12.1.1.1. Each ungrounded conductor
connected to a battery charger, alternator, or other
charging source, shall be provided with overcurrent
protection within a distance of seven inches (175mm)
of the point of connection to the DC electrical system
or to the battery.
EXCEPTIONS: 1. If the conductor is connected
directly to the battery terminal and is contained
throughout its entire distance in a sheath or
enclosure such as a conduit, junction box, control
box or enclosed panel, the overcurrent protection
shall be placed as close as practicable to the battery,
but not to exceed 72 inches (1.83m).

BTW I am not a marine expert by any mean. Just a boat owner that tries to understand some of the requirement.

Thank you John!
I should know these answers as it was my profession, I had an accident in Aug and for one reason or another I can't get it together, soon I hope!
