DANGER
Hazardous voltage. Moving parts.
Will cause severe injury or death.
Operate the generator set only when
all guards and electrical enclosures
are in place.
Electrical backfeed to the utility. Hazardous backfeed
voltage can cause severe injury or death. Connect the
generator set to the building/marina electrical system only
through an approved device and after the building/marina
main switch is turned off. Backfeed connections can cause
severe injury or death to utility personnel working on power
lines and/or personnel near the work area. Some states and
localities prohibit unauthorized connection to the utility
electrical system. Install a ship-to-shore transfer switch to
prevent interconnection of the generator set power and shore
power.

6.1 AC Voltage Connections

Make AC connections to the generator set inside the
junction box. Typically, the generator set connects to a
ship-to-shore transfer switch that allows the use of
shore/utility power when docked or generator set power
when docked or at sea. The wiring then connects to a
main circuit breaker box (panel board) that distributes
branch circuits throughout the craft. See Section 8 for
reconnection of the generator set.

6.2 Circuit Protection

The AC circuit breakers (optional) protect the wiring
from the AC circuit breakers to the vessel's distribution
panel. AC circuit breakers trip when they detect a fault in
the output circuit.
After correcting the fault, reset the AC circuit breaker(s)
by placing them in the ON position. Restart the unit. Do
not start the unit under load.
configuration determines the circuit breaker selection.
Note: Circuit breaker ampere rating and availability are
subject to change.

Circuit Breaker Considerations

Mounting location. Mount the circuit breakers in the
generator set's junction box. See Section 6.2.2.
Sizing. Use the generator set voltage/frequency
configuration to determine
amperage. If the generator set voltage configuration
changes, change the circuit breaker to provide optimum
protection.
For circuit breaker
information, contact an authorized distributor/dealer.
Have a qualified electrician or technician install circuit
breakers and reconnect the generator set. Comply with
all governing standards and codes.
