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?

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.

11.10. LOAD CALCULATIONS
11.10.1. FOR DC SYSTEMS
11.10.1.1. The following method shall be used for
calculating the total electrical load requirements for
determining the minimum size of each panelboard,
switchboard, and their main conductors. Additionally
this information may be used to size the alternator, or
other charging means, and the battery. (See E-
11.7.1.1.1 and ABYC E-10, Storage Batteries.)
11.10.1.1.1. In column A of TABLE II,
Electrical Load Requirements Worksheet, list the
current rating (amps) of the loads that must be
available for use on a continuous duty basis for normal
operations;
11.10.1.1.2. In column B of TABLE II, list the
current rating (amps) of the remaining loads that are
intermittent, and total these loads. Take 10% of the
total load in column B, or the current draw of the
largest item, whichever is greater, and add this value
to the total from column A to establish the total
electrical load.
NOTE: Calculations are based on the actual
operating amperage for each load, and not on the
rating of the circuit breaker or fuse protecting that
branch circuit.

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.
