3-22. FIELD SHUNT CONTACTOR (cont)
26. Install field shunt contactor assembly (5
) in electrical equipment cabinet and install two capscrews (4), flat washers
(3), lockwashers (2), and nuts (1).
Incorrect electrical connections to terminals will result in damage to
stationary contact tip (13) and movable contact tip (23), since arc
suppression feature will be nullified.
27. Connect electrical wires in accordance with wiring diagram and remove tags.
28. Measure contact tip overtravel as follows:
Overtravel is the distance a movable contact tip would travel after
touching the stationary tip if the stationary tip were then removed.
Measure overtravel by either method 1, pin at A, or method 2, pin at B. Refer to table 3-1 for amount of
overtravel and size of pin required to measure that amount.
