The 50 Amp breaker
simultaneously limits
each power supply
conductor to no more than
a short-term maximum
of 50 Amps for each
conductor. 50 Amp
service actually provides
80 continuous amps.
Use care when hooked to
anything less than 50 Amp
shore service.
Shore power service less
than 50 Amps consists
of one power supply
conductor, a neutral and
a safety ground; 30 Amp
shore service is limited
to 24 continuous amps.
20 Amp shore service is
limited to 16 continuous
amps.
Due to outlet congurations
for each type of shore power
service, electrical adapters are
required to adapt the plug end of
the shore cord to the different type
of outlets. For safety, use only
UL approved adapters. The most
common adapter is a 50-30 amp
adapter.
This adapts the 50 amp plug of
the shore cord to a 30 amp shore
power outlet. Always install the
adapter to the cord prior to making
the connection to the outlet.
Another common
adapter is a 30 to 20
amp adapter. If all
that is available is 20
amp service, it will be
necessary to use both
adapters. This type of
connector adapts the 30 amp plug
to a 20 amp shore power outlet.
CAUTION:
If shore power service is
limited to 15 or 20 amps,
use of light duty extension
cords and electrical
adapters will create a
voltage loss through the
cord and at each electrical
connection. Line voltage
loss and the resistance at
each electrical connection
can be a hazardous
combination. Damage
to sensitive electronic
equipment may result!
WARNING:
Before working on
the electrical system,
disconnect from shore
power and turn off the
inverter. Disconnect
the negative 12 Volt DC
battery cables at the
batteries. Remove rings,
metal watchbands and
other metal jewelry before
working around batteries
and connectors. Use
caution when working
with metal tools. If the tool
contacts a battery terminal
or metal connected to it, a
short circuit could occur
causing personal injury,
explosion or fire.
LOAD CENTER
The load center receives power
from the transfer switch supplied
by either shore power or the
generator. AC power is supplied
to the 50 Amp main breaker
rst, then power is supplied to
individual branch circuit breakers.
The panel label describes the
breaker layout and item, outlet or
appliance to which they pertain.
WARNING:
The load center contains
high voltage that can cause
serious injury or death.
Unplug from shore power,
turn off the generator
and the inverter before
performing any testing
procedures or repairs
involving the load center
or any branch circuits.
Disable the Auto Gen Start
feature. Certain testing
procedures may require the
AC power to be on. Only
qualified personnel with
electrical backgrounds
should attempt any testing
procedures or repairs.
