AC Installation (continued)
2. Install feed circuit wires
Install the feed wires from the shore power inlet or other AC source, referring to the wire sizing chart to select the correct wire size. Connect the black AC hot, white AC neutral and green AC safety ground as shown in the illustration.
If the feed wires are from the shore power inlet or the electrical attachment point of a permanently installed shore power cord and the inlet or attachment point is more than 10 feet from this panel, additional fuses or circuit breakers must be installed within 10 feet of the shore power inlet. The measurement is made along the conductors.
3. Optional Branch LEDs
This panel is supplied with LEDs
Note
This Blue Sea Systems electrical distribution panel is furnished with 15A or 8A circuit breakers for AC branch circuits. 15A circuit breakers are used in all 120V panels and 8A circuit breakers are used in all 230V panels. These ratings will satisfy the vast majority of marine circuit protection situations.
Panel Mounting and Testing
1. Apply branch circuit labels and mount panel
Apply a label for each circuit from the label set provided. If the appropriate label is not included, extended label sets are available through retail suppliers, and over 500 individual labels are available directly from Blue Sea Systems. Please go to www.bluesea.com to order stock or custom labels for specific applications.
Fasten the panel to the mounting surface using the screws provided.
2. Testing
]Reconnect the main positive cable to the battery terminals and turn the main switch on to supply power to the panel. Turn on all branch circuits and test the voltage at the panel. Compare this voltage to the battery terminal voltage to determine that the voltage drop is
within 3%. With all branch circuits still on, test the voltage at one device on each circuit to determine that there is a 3% or 10% drop as is appropriate.
]Connect the shore power cable to the boat AC power inlet. Do not connect the shore power cable to the shore power pedestal. Instead run the shore power cable such that the shore power plug is next to the AC panel. With an Ohmmeter verify that the pins of the shore power plug are connected to the appropriate terminals of the panel. Refer to ABYC
]Connect the vessel’s shore power and verify the Reverse Polarity light is not illuminated. If the red Reverse Polarity light is on then
either the hot and ground or the hot and neutral wires have been crossed. Starting at the panel, trace the connections back as far as necessary to locate the error.
]Using a multimeter where the power source is connected to the panel verify:
PN 8095 / PN
a.120 volts between hot and neutral
(nominal, this may vary depending on source voltage)
b.120 volts between hot and ground.
c.0 volts between neutral and ground.
PN 8195 / PN
a.230 volts between hot and neutral
(nominal, this may vary depending on source voltage)
b.230 volts between hot and ground.
c.0 volts between neutral and ground.
]Turn on each branch circuit to verify power to each circuit.
