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 Figure 3A); 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 conductor, size No. 8
AWG or larger. Run wire from external bonding lug (see Figure 3A) to rein-
forcing rod or mesh.
Wiring:
Pump must be permanently connected to circuit. Table I, Page 7, gives cor-
rect 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 circuit; it will sense a
short-circuit to ground and disconnect power before it becomes dangerous
to pool users. For size of GFCI required and test procedures for GFCI, see
manufacturer’s instruction.
In case of power outage, check GFCI for tripping (which will prevent normal
pump operation). Reset if necessary.
NOTICE:
If you do not use conduit when wiring motor,
be sure
to seal wire
opening on end of motor to prevent dirt, bugs, etc., from entering.
Connect dual voltage 115/230V motors to power supply as shown in Figure
3B. Connect single voltage and 3-Phase motors as shown on motor nameplate.
