3. ELECTRICAL & WIRING
WARNING
Ground and bond the motor before connecting to an electrical power supply.
Failure to ground and bond pump motor can cause a serious or fatal electrical
shock.
See section below for Grounding and Bonding instructions.

WARNING
Do
NOT
ground to a gas supply line.
To avoid dangerous or fatal electrical shock, turn
OFF
power to motor before
working on electrical connections.
Ground Fault Circuit Interrupter (GFCI) tripping indicates electrical problem. If
GFCI trips and won’t reset, consult electrician to inspect and repair electrical
system.
Fire Hazard.
Match supply voltage to motor nameplate voltage.
Ensure that the electrical supply available agrees with the motor’s voltage,
phase, and cycle, and that the wire size is adequate for the H.P. (KW) rating
and distance from the power source.
NOTE - All electrical wiring MUST be
performed by a licensed electrician, and MUST conform to local codes and
NEC regulations.
Use copper conductors only.
VOLTAGE
Voltage at motor
MUST NOT
be more than 10% above or below motor name plate rated voltage, or
motor may overheat, causing overload tripping and reduced component life. If voltage is less than
90% or more than 110% of rated voltage when motor is running at full load, consult Power Company.
Grounding and Bonding
Install, ground, bond, and wire motor in accordance with local or national electrical code
requirements.
Permanently ground motor. Use green ground terminal provided under motor canopy or access place;
use size and type wire required by code. Connect motor ground terminal to electrical service ground.
Bond motor to pool structure. Bonding will connect all metal parts within and around the pool with a
continuous wire.
Bonding reduces the risk of a current passing between bonded metal objects, which could potentially
cause electrical shock if grounded or shorted.
Reference NEC codes for all wiring standards
including, but not limited to, grounding, bonding, and general wiring procedures.
Use a solid copper conductor, size 8 or larger. Run wire from external bonding lug to reinforcing rod
or mesh. Connect a No. 8 AWG (8.4 mm2) solid copper bonding wire to the pressure wire connector
provided on the motor housing and to all metal parts of swimming pool, and to all electrical
equipment, metal piping (except gas piping), and conduit within 5 ft. (1.5 m) of inside walls of
swimming pool, spa, or hot tub.
