WIRING DIAGRAMS SECTION 4
The standard disposer motor voltages are 115/208/230 volts for
single phase electrical power and 208/230/460 volts for three phase
electrical power.
NOTE
Three phase contactors require three sets of contacts to carry line
voltage to the disposer, while single phase contactors require four
Circuitry and parts function on all control centers are identified
within their respective models. This applies to all component parts
controlled by or on the secondary voltage side of the transformer,
whether it is a 1 phase or 3 phase control center.
The wiring (circuitry) to the line voltage connections on the Reversing
contactors are identical on all 3 phase (only) contactors. The wiring
(circuitry) to the line voltage connections on the Reversing contactors
are identical on all 1 phase (only) contactors.
sets. Two identical contactors are utilized in every control center to
perform the function of reversing the disposer motor rotation.
Therefore, the wiring diagrams in this section (Figs. 4-12 through 4-
19) show 3 phase contactors but can be used to diagnose or trace
circuitry for 1 phase or 3 phase control centers, keeping in mind that
only the contactors are different from 1 phase to 3 phase. Refer to
Figs. 4-10 and 4-11 for 1 phase contactor connections.
CAUTION
All electrical connections must conform to local codes. Be
certain that all IN-SINK-ERATOR disposers and control centers
are carefully and permanently grounded.
ELECTRICAL INSTALLATION
WARNING
BEFORE ANY ELECTRICAL WORK IS PERFORMED, REMOVE LINE
POWER FROM THE DISPOSER CONTROL CENTER BY TURNING OFF
THE CIRCUIT BREAKER. USE A VOLTMETER OR CIRCUIT TESTER TO
ENSURE THAT POWER IS OFF BEFORE PROCEEDING.
CAUTION The control center and
disposer motor voltage and phase must be the same as the
electrical supply. Check name-plates on both units for ratings.
All connections must conform to local codes. Ground the
disposer control center, the disposer, and all control boxes.
The following wiring diagrams are included to illustrate the electrical
connections for each standard model of disposer control center and
disposer motor. For each standard model of disposer control center,
wiring diagrams are shown to illustrate the most typical configura-
tions. The wiring diagrams include motor connections. Since various
options can be custom ordered for a control enter, the wiring
diagrams for a particular model of control center do not reflect every
possible option. Additional wiring diagrams illustrating various special
(nonstandard) configurations of each model are provided in section
10 of this manual.
