1. AC
Source
The Shore Power Receptacle and Distribution Panel limit the current draw of the entire AC
Electrical system to 30AMPS.
The Shore Power Receptacle and Shore Power Cord have plug end configurations that ensure
proper AC current enters the boat’s electrical system. The configuration also limits plugging into a
30amp source only.
120VAC 30AMP PLUG CONFIGURATION
NOTE
A voltmeter reading between the Grounding Bond and Grounded Neutral positions of the
receptacle on shore must show zero volts. A voltmeter reading of 110VAC to 120VAC should be
found only between the Ungrounded Line and Grounded Neutral and between the Ungrounded
Line and Grounding Bond positions of the receptacle on shore. A shore receptacle that does not
give proper voltmeter readings between these positions must be re-wired.

2. Distribution
The Distribution section of the AC Electrical System controls, monitors and ensures proper
current flow through the AC Electrical System.
The AC distribution section has four components:
1. Distribution
Panel
2. Grounded Neutral Bus Bar
3. Grounding Bond Bus Bar
4. Galvanic
Isolator
DISTRIBUTION PANEL
The AC Distribution Panel provides control and protection of the AC Electrical System on the
boat.
The AC Distribution Panel is divided into two sections:
Distribution
Accessories
The Distribution section of the panel is primarily the Shore Power Circuit Breaker. This circuit
breaker protects the Shore Cord and the wiring between the Shore Cord Receptacle on the boat
and the Distribution Panel. The circuit breaker limits the amount of current passing thru this wiring
to 30 amps.
The 30 amp Shore Power Circuit Breaker must be ON if AC power is to be supplied to the
accessories. Turning this circuit breaker OFF will allow no AC Power beyond the distribution
panel
