RECOMMENDED INSPECTION AND MAINTENANCE TYPES

NOTE: Refer to the SAFETY section of this manual for important information.

A.Acceptance Inspection

This inspection confirms that the circuit breaker unit is complete, correct as specified, and undamaged from shipment. The procedure for this inspection is outlined in the

RECEIVING, INSPECTION AND HANDLING section of this manual.

B.Patrol Inspection

Inspection is made of the condition of the circuit breaker while it is energized. Check that no unusual sounds or smells exist externally.

Inspection Frequency: Once every 6 months

C.Periodic Inspection

Inspection is performed with the circuit breaker de-energized. The lubrication of sliding and rotating parts is checked and the mechanism is lubricated if needed.

Inspection Frequency: Once every 1-3 years or every 3000 operations (normal). Once every 6 years (detailed).

Refer to Table 2 for the schedule of Periodic Inspections.

D.Unscheduled Inspection

Inspections are implemented as required. Inspection Frequency: As needed

NOTE: The inspection frequency and points to be inspected may vary from the above recommendations depending on the status of use, frequency of switching, amount of current interrupted and other factors.
