Electrical Connections Gc25E - Norton GC55 Owner's Manual

E. Electrical Connections GC25E
Important-Before connecting the motor leads to the power supply be
sure that the voltage, cycles and phase shown on the nameplate of the
motor correspond to the available power supply. Voltage Selection for
the GC25E 3 HP motor is single phase saw motors witch have a dual voltage
capable. Either a 115-volt or 230 volt power supply can be used. To change
voltage simply move the voltage change switch located on the front of the motor
to the required voltage, no rewiring is required. Wherever possible, use 230-volt
power supply for best operation.
Failure to run the motor on the proper voltage will damage the motor and
is not covered under warranty. Improperly wired motors are not covered
under warranty.
The GC25E models are wired for 115 Volt from the factory!!!
Power Connections
Connect the power supply to the pigtail leads of the switch. Direct wiring
connection is preferred, but an extension cord with an electrical plug with 30-amp
minimum capacity may be used. A 30-amp circuit breaker is recommended.
Connecting wires should be as short as possible and in one piece. In no case
should the connecting wires be longer than shown in the following table for use
with the GC25E Single-phase motors:
Wire Gauge
Number 12
Number 10
Number 08
Caution-When wires that are too small gauge or too long are used, loss of
power, over heating, or possible damage to the motor will result. Damage
or failure of motors due to incorrect power supply cord lengths are not
covered under any warranty.
Always use the proper wiring connectors that are UL/CSA approved to
attach the motor to the electrical supply. Any wiring hook ups should be
made by qualified personal and made to National Electrical Code and to
any Local Codes.
Generators:
If a generator must be used, it must be of 8kW or larger. The generator must
have a 30A circuit and capable of providing a minimum of 8kW at the required
voltage. Under size generators will cause motor damage and is not covered
under warranty.
