Centrifugal Pump Installation and User’s Guide
Wiring Installation,
(continued)
3. For wiring sizes and general guidelines for proper electrical installation, please follow the specifications
defined in the National Electric Code and any local codes as required.
4. Make sure all electrical connections are clean and tight.
5. Cut wires to the appropriate length so they don’t overlap or touch when connected to the terminal board.
Never work on pump while it is running or power is still connected; hazardous voltage can cause severe
or fatal injury. A suitable ground fault interrupter should always be installed at the power supply source of
the unit.
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.
6. The Challenger
®
Centrifugal Pump motor must be wired for the proper voltage in accordance with the
wiring diagram supplied with the motor.
Wiring the motor with the incorrect supply voltage will cause damage to the motor and void the
warranty.
7. The wiring to the motor should be kept as short as possible and large enough NOT to cause an
excessive voltage drop.
8. Install, ground and bond wire according to local or National Electrical Code requirements.
9. Bond the motor to the pool structure in accordance with the National Electrical Code. Use a solid No. 8 AWG
or larger copper conductor (No. 6 AWG for Canadian installations). Run a wire from the external bonding
screw on the motor to the pool bonding structure.
Grounding
Permanently ground motor. Use green terminal provided under motor canopy or access plate; use size and type
wire required by code. Connect motor ground terminal to electrical service ground. On cord connected circuits,
check for proper grounding.
Bonding
The National Electrical Code Article 680-22 requires that the motor be electrically bonded to appropriate
permanently installed pool or spa/hot tub structure by a solid copper conductor no smaller than No. 8 AWG (no
smaller than No. 6 AWG for Canadian installations). Bonding wire should be connected from the accessible wire
connector on the motor shell to all metal parts of the swimming pool spa or hot tub structure and to all electrical
equipment, metal conduit and metal piping within five (5) feet of the inside walls of a swimming pool spa or hot tub.
A grounding lug is provided on the exterior of the motor shell for this purpose.
This pump is for use with permanently installed pools and may also be used with hot tubs and spas. Do
not use with storable pools unless pump is protected by a factory installed double insulated enclosure.
A permanently installed pool is constructed in or on the ground or in a building such that it cannot be
readily disassembled for storage. A storable pool is constructed so that it may be readily disassembled
for storage and reassembled to its original integrity and has a maximum dimension of 18 feet and a
maximum wall height of 42 inches.
Do not install within an outer enclosure or beneath the skirt of a hot tub or spa unless so marked.
To reduce the risk of electric shock, do not use extension cord to connect unit to electric supply; provide
a properly located outlet.
To reduce the risk or electric shock, replace damaged cord immediately.
Do not bury cord. Locate cord to minimize abuse from lawn mowers, hedge trimmers, and other
equipment.
RISK OF ELECTRIC SHOCK. Connect only to a grounding type receptacle protected by a ground-fault
circuit-interruptor (GFCI). Contact a qualified electrician if you cannot verify that the receptacle is
protected by a GFCI.
