ELECTRICAL
WIRING CONNECTIONS
FIRE HAZARD. Incorrect voltage can cause a
fire or seriously damage the motor and voids the warranty. The
supply voltage must be within ±10% of the motor nameplate
voltage.
Dual-voltage motors are factory wired for 230 volts. If

necessary, reconnect the motor for 115 volts, as shown. Do
not alter the wiring in single voltage motors.
Install, ground, wire, and maintain your pump in compliance

with the United States National Electrical Code (NEC) or the
Canadian Electrical Code (CEC), as applicable, and with all
local codes and ordinances that apply. Consult your local
building inspector for code information.

CONNECTION PROCEDURE
1. Connect the ground wire first (Figure 9). The ground wire
must be a solid copper wire at least as large as the power
supply wires.
2. There must be a solid metal connection between the
pressure switch and the motor for motor grounding
protection. If the pressure switch is not connected to the
motor, connect the green ground screw in the switch to the
green ground screw under the motor end cover. Use a solid
copper wire at least as large as the power supply wires.
3. Connect the ground wire to a grounded lead in a service
panel, to a metal underground water pipe, to a metal well
casing at least ten feet (3M) long, or to a ground electrode
provided by the power company or the hydro authority.
4. Connect the power supply wires to the pressure switch as
shown in Figure 9.
