1.

Introduction
:

This do
cument provides the specifications and parameters for a DC distribution panel as a
replacement for the original equipment supplied with the J/30 Sailboat. The replacement panel is
intended to provide the necessary isolation and circuit protection for orig
inal J/30 load
requirements, and provide additional circuits for equipment that owners may have installed. The
replacement panel is also intended to provide measurement capability for voltage and current.


2.

Background
:

Information provided by J/30 owners r
evealed at least two different types of DC panels were
supplied throughout J/30 production between 1979 and 1986. Older style panels were
manufactured by Lorco and contained twelve toggle switches and twelve 3AG panel mounted
fuse sockets with screw style

caps. The panel measured 8.5” wide by 8” high. Some newer
boats used a similar panel that measured 10” high by 6.325” wide. Additionally, some J/30
owners reported having a DC voltmeter mounted near the battery with a selector switch to
monitor either
battery. Not all J/30s were equipped with this meter.

Requirements
:

The requirements specified below shall be met for the replacement 12 volt DC electrical panel.

4.1

Electrical Requirements:

The

DC Panel shall
utilize hydraulic/magnetic trip
-
free circuit breakers that meet the
requirements of UL
-
1077 and ABYC 11.10.1.5.

.

4.1.1

Main Breaker
:

The

DC Panel shall have a single 50 amp circuit breaker with a 3000 amp interrupt rating that
isolates the branch breakers.

4.1.2

Branc
h Breakers:

The DC Panel shall have twelve branch circuit breakers. The breakers shall be available in the
following ratings and may be specified individually at the time of order: 5, 10, 15, 20, 25, 30, 40
or 50 amps.

4.1.3

Bus Bars:

The DC Panel shall have
separate tin plated DC Negative Bus and DC Grounding Bus bars. The
DC Negative bus bar is intended to be the DC return path for all loads. The DC Grounding Bus
is not intended to be the load path, but will be connected to the DC Negative Bus. The bus ba
rs
shall have sufficient capacity for attaching the return path for each DC branch and the ground for
each DC branch.

4.1.4

Multimeter:

The DC Panel shall have a single splash proof panel mounted DC digital multimeter with the
following attributes:



Displays cur
rent in 0.1 Amp increments for
-
99.9 to +500 amp range, 1.0 Amp
increments for
-
100 to
-
500 amp range with current monitored by installing a shunt
supplied with the DC Panel on the negative side near the battery. This shunt is connected
to the meter via 1
6 AWG twisted pair to minimize noise. The shunt shall be sized to
match the desired current range with the multimeter sensitivity.



Accuracy +0.5% corresponding to +1 least digit of resolution



Four digits composted of seven segment displays with decimal po
int available to the right
of each digit. Digits sized at 9/16” tall.



Illuminated indicators that display Voltage (V) or Current (A) modes.



Displays voltage from 0 to 60 Volts in 0.01 Volt increments

.



Input 8 to 50 VDC to power meter with a maximum power c
onsumption of 1.0 watt and
standby power consumption of less than or equal to 0.15 watts



Provides separate voltage and current terminals with a menu that allows selection
between current and voltage.



Menu selectable high and low voltage with audio and visu
al alarms



Three levels of display brightness with a programmable sleep mode to blank display for
power conservation

4.1.5

Voltage Selector Switch:


A
four

position switch shall be provided to select the DC voltage monitor point for the
Multimeter. The points to

be monitored include

Off,

Battery 1, Battery 2 and DC Panel Bus.
Connection to the DC Panel Bus shall be internal to the panel. Connection to the switch for
Battery 1 and Battery 2 shall be via
female insulated blade connector
terminals using external
1
4
-
18 AWG wire fused near the battery and provided by the installer.


4.1.5: Panel Illumination:


The

panel shall have back lighting that is powered from the load side of the main breaker with
the illumination load for all back lights less than 90 milliamps
. The back lighting is intended to
illuminate circuit breaker labels. LED indicators shall be provided next to each circuit breaker
that illuminate when the respective breaker is closed.

4.2

Mechanical Requirements:

The

DC Panel shall be 11” wide, 8.25” hig
h and extend no more than 3.5” behind the panel. The
panel shall be fabricated from 0.125” corrosion resistant aluminum. All component mounting
hardware and the panel mounting hardware shall be countersunk resulting in a flush surface.

Refer to Figure 1

for DC Panel layout.

4.2.1

Hinge

& Panel Mounting
:


The panel shall be configured with a hinge that extends along the bottom edge of the panel,
allowing the panel to swing down for service. The hinge shall be mounted
to the panel
with
recessed hardware

on the
face of the panel. When the panel is in the closed position flush with


12 Volt DC Distribution Panel

.

the mounting surface, the hinge shall be open 90 degrees with the hinge edge attached a
horizontal surface that projects 1 inch behind the inner face of the panel. The hinge shall be
drilled by the installer for mounting on the horizontal surface.
The hinge shall
project 0.
0625

inches between the panel and the mounting surface along the lower edge. It is the responsibility
of the installer to provide suitable relief for the hinge on
the lower edge, or build up the edges on
the mounting surface (e.g. gasket material or bezel) to provide a flush finish when the panel is
closed.

The panel shall be mounted using countersunk #8 flat

head
or oval head screws
.

The
area to be cut out behind

the panel to accommodate the hinge, and provide clearance for panel
mounted components is shown in Figure 2.

4.2.2

Finish:


The panel shall be painted black with a two part polyurethane finish. A 0.125” white accent line
shall be painted around the outer edge
with radiused corners. White lettering shall be painted on
the panel as follows:

The DC Panel shall be configured with two columns of circuit breakers. The top left breaker
shall be the main breaker. Below this shall be seven branch breakers. The rig
ht column shall
have the multimeter and voltage selector switch mounted at the top. Below these components
shall be five branch breakers.

Refer to Figure 1 for panel layout.
