Ground submersible motor in accordance with all codes
and ordinances that apply. Use copper ground wire at
least as large as wires carrying current to motor.
Motor is supplied with copper ground wire. Splice to cop-
per conductor that matches motor wire size specified in
Table 3. See “cable splicing” under installation.
Permanently ground pump, motor and submersible motor
control before connecting power cable to power supply.
Connect ground wire to approved ground first, then con-
nect equipment being installed.
To avoid over-heating wire and excessive voltage drop at
motor, be sure wire size is sufficient per NEC standards for
the pump horsepower and length of wire run.
NOTICE: See installation Wiring Diagrams for typical wiring
hookups and submersible motor control identification.
ELECTRICAL
All wiring must meet National Electrical Code or Canadian
Electrical Code and local code requirements.
Use only copper wire for connections to pump and sub-
mersible motor control.
