SECTION 2 - GENERATOR FRONT AND REAR PANELS
2.1-
INTRODUCTION
(Figures 2-1, 2-2)
The generator FRONT PANEL (Figure 2-1) mounts
(a) a 50 ampere RECEPTACLE, (b) a 50 ampere
CIRCUIT BREAKER, and (e) the generator MAIN
CIRCUIT BREAKER. The generator REAR PANEL
(Figure 2-2) mounts (a) a pair of 120 volts
RECEPTACLES, (b) two 15 ampere CIRCUIT BREAK-
ERS, (c) a VOLTMETER, and (d) a MODULAR CONN-
ECTOR ACCESS DOOR. The REAR PANEL is easily
visible from the power takeoff (PTO) end of
the unit.
2.3- 50 AMPERE CIRCUIT BREAKER (Figure 2-11
This circuit breaker protects the 50 ampere
panel receptacle against current overload.
Any attempt to connect electrical loads re-
quiring more than 50 a-c amperes to the 50
ampere panel receptacle will result in a
tripped (open) circuit breaker and loss of
output from the receptacle. The circuit
breaker may be manually reset to its ON or
CLOSED position.

CAUTION!
If the circuit breaker trips (opens) whenever
an electrical load
is connected to the
receptacle and turned ON, first make sure the
connected load does not require more than 50
amperes of current (12,000 watts or power).
If circuit breaker current and power ratings
are not exceeded, the connected load may be
shorted or the breaker may be defective.
NEVER HOLD THE CIRCUIT BREAKER IN WHILE OPER-
ATING ELECTRICAL LOADS, OR SERIOUS DAMAGE TO
THE GENERATOR OR CONNECTED LOADS MAX RESULT.
2.4= MAIN CIRCUIT
BREAKER
(Figure 2-1)
The MAIN CIRCUIT BREAKER protects the
generator stator windings and wiring against
current overloads in excess of the unit's ra-
ted a-c power capacity. This generator is

a
This panel RECEPTACLE may be used to power
240 volts, single phase, 60 hertz a-c elec-
trical loads requiring up to 50 a-c amperes
or up to 12,000 watts (12.0 kW) of power. The
240 volts a-c loads must be connected across
receptacle LINES 20 and 30 (see Figure 2-1).
As shown in Figure 2-1, 120 volts, single
phase, 60 hertz a-c loads may also be connec-
ted to the receptacle. Connect these loads
across lines 20 (hot) and 10 (neutral), or a-
cross lines 30 (hot) and 10 (neutral).
