Electrical Connections
Before wiring the pump to the power source, verify that the voltage of the motor matches the voltage of the
power supply. (See Motor Nameplate) The supply voltage must be within + 10% of nameplate voltage.
Wire the motor according to the diagram shown on the motor nameplate. If the nameplate diagram differs from
the wiring diagram shown in this manual, follow the nameplate diagram.
Install ground wire and maintain this pump in compliance with the National Electrical Code (NEC) or the
Canadian Electrical Code (CEC) and with all local codes and ordinances that apply. Consult your local building
inspector for local code information.
The motors used on the PC Series Centrifugal Pump are manufactured by Emerson, Baldor, Century or Franklin
Electric. Both 1 phase and 3 phase motors are factory wired for 230 volts.
If the supply voltage for a 1 phase motor is 115 volts refer to the wiring diagrams shown below to properly rewire
the motor.
