Load Connections
The generator's data plate gives the voltage, current and frequency rating of the generator. An AC wiring
decal
is affixed to the inside of the louvered cover on the generator end. A diagram of the various AC volt-
age connections
is provided on the decal.
The generator
is a single-phase, reconnectable 120 volts AC two-wire or 120/240 volts AC three-wire, at 60
hertz; or 110 volts AC two-wire, 110/220 volts AC three-wire, or 220 volts AC two-wire, at 50 hertz. Refer to
the
"SYSTEM SPECIFICATIONS" seclion of this manual for the 4.5 I<W BCG generator rating, page 11.
NOTE: The frame ground wire ~ be moved when changing from 110 volts, 50 hertz to /220
volts, 50 hertz.
A circuit breaker should be installed between the generator and the
AC load. This circuit breaker should be
rated at
120% of the generator's AC output and be able to react quickly to overloads, subject to motor start-
ing considerations.

For making connections to the AC terminal block, use terminal ends for #10 studs which will accept mulli-
strand wire sized for the number of conductors in the bundle, the rating
of the conductor's insulation, and
amperage that will be drawn through the conductor(s). (Refer
to the generator's data plate for the gener-
ator's amperage and voltage ratings.)
NOTE: When changing hertz produced by the generator, an engine speed adjustment at the
governor
~ be made. The AC output connections on the above illustrated terminal blocks
~ be selected for the voltage and hertz to be produced. A plug at the capacitor ~ be
changed for
50 (#5) or 60 (#6) hertz use. Early models with 3 wire connections tothe integral
controller require a
50 (#5) or 60 (#6) hertz connection change at the bridge rectifier in the
DC charging circuit. Refer to the "Generator's Internal Wiring Schematic" on page 51.
