ELECTRICAL
Ground motor before connecting to electrical
power supply. Failure to ground motor can cause
severe or fatal electrical shock hazard.
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 an electrical problem. If GFCI trips and
will not reset, have a qualified electrician inspect and
repair electrical system.
Exactly match supply voltage to nameplate volt-
age. Incorrect voltage can cause fire or seriously
damage motor and voids warranty. If in doubt consult a
licensed electrician.
Voltage
Voltage at motor must be not more than 10% above or
below motor nameplate rated voltage or motor may
overheat, causing overload tripping and reduced compo-
nent life. If voltage is less than 90% or more than 110%
of rated voltage when motor is running at full load, con-
sult power company.
Grounding/Bonding
Install, ground, bond and wire motor according to local
or National Electrical Code requirements.
Permanently ground motor. Use green ground terminal
provided under motor canopy or access plate (See Fig.
3); use size and type wire required by code. Connect
motor ground terminal to electrical service ground.
Bond motor to pool structure. Use a solid copper conduc-
tor, size No. 8 AWG (8.4 sq.mm) or larger. Run wire from
external bonding lug (see Fig. 3) to reinforcing rod or mesh.
Connect a No. 8 AWG (8.4 sq.mm) solid copper bond-
ing wire to the pressure wire connector provided on the
motor housing and to all metal parts of the swimming
pool, spa, or hot tub and to all electrical equipment,
metal piping or conduit within 5 feet (1.5 m) of the in-
side walls of swimming pool, spa, or hot tub.
Wiring
Pump must be permanently connected to circuit. Table I,
Page 8, give correct wire and circuit breaker sizes for the
pump alone. If other lights or appliances are also on the
same circuit, be sure to add their amp loads to pump
amp load before figuring wire and circuit breaker sizes.
(If unsure how to do this or if this is confusing, consult a
licensed electrician.) Use the load circuit breaker as the
master on-off switch.
Install a Ground Fault Circuit Interrupter (GFCI) in cir-
cuit; it will sense a short-circuit to ground and discon-
nect power before it becomes dangerous to pool users.
For size of GFCI required and test procedures for GFCI,
see manufacturer’s instruction.
