INSTALLATION WIRING INSTRUCTIONS
Single Phase, 3 Wire
Hazardous voltage. Can shock, burn, or kill.
Ground control box, all metal plumbing, and motor frame with cop-
per wire in compliance with Canadian Electrical Code or National
Electrical Code and local codes. Use ground wire at least as large
as the wires supplying power to motor.
At well head, connect ground wire to grounding terminal that meets
Canadian Electrical Code or National Electrical Code requirements
that apply. For more information, contact local code officials.
Permanently close all unused openings in this and other equipment.
Disconnect power before working on or around control box, pipes,
cable, pump, or motor.
NOTICE: Install control box vertically on wall with top side up.
3-Wire pumps have three power supply wires (Red/Black/Yellow)
and one ground wire (Green).
3 wire pumps will not operate without control box, and will burn out
motor.
Installations must include circuit and component protection in com-
pliance with U.S. National Electrical Code or Canadian Electrical
Code, Part 1.
If main overload trips, look for:
1. Shorted Capacitor
2. Voltage Problems
3. Overload or locked pump.
NOTICE: Use only control box specified for your pump. Make
sure motor and control box match (Table 4). FAILURE TO DO
SO WILL VOID WARRANTY. Franklin motor and control box model
numbers may include additional suffix numbers to the right of the
numbers shown here. These additional numbers are not important
for control box selection.
Table 4: Control Box Chart
For motors of 1-1/2 HP and above, use magnetic
starter to avoid damage to pressure switch. Consult factory for
wiring information.
Fig. 1A – 3 wire - 1/2 thru 1 HP quick disconnect box.
Single Phase, 2 Wire
2-Wire pumps have two power supply wires (Red/Black) and one
ground wire (Green). Control box is not required.
See Figure 1B for correct hook-up information for 230 Volt 2-Wire
motors only.

NOTE:
1. Maximum wire lengths shown maintain motor voltage at 95%
of service entrance voltage, running at maximum nameplate
amperes. If service entrance voltage will be at least motor
nameplate voltage under normal load conditions, 50% addi-
tional length is permissable for all sizes.
2. Sizes given are for copper wire. For aluminum wire go two
sizes larger (i.e., if table lists #12 (3mm
2
) copper wire, use #10
(5mm
2
) aluminum wire.)
