14.1.5 Check starter main and auxiliary contact condition and alignment.
14.1.6 Check starter and circuit breaker components for cleanliness, including all
seating surfaces of unplated and laminated magnet faces. Remove any rust or
rust preventative.
14.1.7 Check size, type, and rating of control power fuses.
14.1.8 Check size and rating of control power transformer.
14.1.9 Check voltage rating of starter coil.
14.1.10 Check mechanical function of all starter and circuit breaker movable parts.
14.1.11 Check all equipment items for conformance to area classification.
14.1.12 Check equipment installations for location of seals, breathers, and drains.
14.1.13 Check for proper equipment labeling.
14.2 Equipment and Installation Inspection Items
14.2.1 Inspect bus bar splice connections for tightness by verifying that the torque
meets manufacturer’s specifications. Verify that connection hardware is
consistent with the project specifications.
14.2.2 Inspect bus bar supports for cleanliness and tightness.
14.2.3 Inspect line connections to bus bar for tightness.
14.2.4 Inspect ground connections to ground bus and/or structure.
14.2.5 For circuit breakers, inspect size, rating, and instantaneous setting. For
power fuses, inspect size, type, and rating.
14.2.6 Inspect starter size, overload heater size, and overload relay setting.
14.2.7 Inspect operation of external overload reset device.
14.3 Testing Requirements
14.3.1 Test insulation resistance of MCC or switchrack bus with a 1-minute test
(phase to phase and phase to ground) with all disconnects in open position.
14.3.2 Test insulation resistance of MCC or switchrack bus with a 1-minute test
(phase to phase and phase to ground) with all circuit breakers in closed
position. If resistance value is less than 100 megohms, remove the CPT fuses
and re-test.
14.3.3 Test operation of all space heaters including switching devices.
14.4 Function Test Items
14.4.1 Function-test control circuit with motor leads disconnected. Close and trip
starter from all control devices, and verify operation of auxiliary devices.
14.4.2 Verify operation of capacitor discharge resistor system on power factor
capacitors using a properly sized voltmeter.
