THREE PHASE OPERATION
All three phase generators operate similarly as single phase units.
Please note that when checking the no load voltage on any three
phase generator, the voltage will be about 10% below nameplate
rating. When a load is placed on the three phase generator, the
reactor transformer inside the generator activates and the voltage
immediately increases to the proper rated voltage of the three phase
generator. If an optional automatic voltage regulator is installed the
voltage regulation is +/- 1½%. The automatic voltage regulator is
required if relays, electric controls, etc. are used with a 3-phase motor.
A three phase plug is included with each unit.
When applying load to the generator, if the electric motor runs in
reverse direction than the motor is supposed to operate, you must stop
the generator, remove the electric load from the generator and then
reverse two of the electric motor leads on the terminal strip of the
motor. Restart the generator, apply the electric motor load and the
direction of the electric motor should be operating properly.
On all three phase generators there is a three phase circuit breaker
rated to the amperage load of each unit. If the circuit breaker trips
under load, you must remove some of the load to prevent over loading
the generator. All three phase circuit breakers are designed for motor
load starting permitting momentary over load conditions associated
with three phase motors.

IN CANADA, ALL CONNECTIONS MUST CONFORM TO CSA AND
HYDRO REQUIREMENTS. CONSULT A LICENSED ELECTRICIAN.

SINGLE PHASE ELECTRIC SERVICE IS BEING SUPPLIED BY THE
UTILITY.
SINGLE PHASE
THE FORMULA FOR WATTAGE IS:
VOLTS X AMPERAGE = WATTAGE
EXAMPLE: 120(VOLTS X 10(AMPS) = 1200 (WATTS)
THREE PHASE
THE FORMULA FOR WATTAGE IS:
VOLTS X AMPERAGE X 1.732 X POWER FACTOR(USUALLY .8) = WATTAGE
VOLTS X AMPERAGE X 1.732 X = VOLT AMPERAGE
