WARNING
Hazardous voltage.
Can 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 Figure 6-1 for
AC voltage connections to the generator set.
Section 8 for reconnection of the generator set.
