Recommended Inspection Maintenance 

 

 

Patrolling Inspection (6 Months) 

The patrolling inspection is a largely visual inspection on an energized unit in service. The frequency of the 

inspection is determined by the local conditions and policies of the owner of the equipment.  

  Inspect the insulators for breaks, cracks, burns, or cement deterioration. Clean insulators particularly 

where abnormal conditions such as salt deposits, cement dust, or acid fumes exist to minimize possibility 

of a flashover.  

  If an accompanying motor operator is supplied, check the cabinet for loose parts and ensure that all 

wiring is secure, the heater is energized, and the door is sealed.  

Routine Inspection and Maintenance (5 year) 

 

 
 

  Perform patrolling inspection (above), checking insulators and cabinet 

  Once the disconnect switch is de-energized, test operate the switch multiple times. 

  Check the switch for alignment, contact pressure, eroded contacts, corrosion, and mechanical 

malfunction, replacing damaged or eroded components if necessary. If contact pitting is minor, smooth 

the surface with a clean, fine sandpaper. It is recommended to clean and reapply        C5-A grease 

during any operation or maintenance cycle, as exposed surfaces 

(such as contacts)

 are vulnerable to 

environmental conditions and contaminants that can decrease the effectiveness of the grease over time. 

During reapplication, clean and wipe down the contact surfaces with a green Scotchbrite pad, reapply 

C5-A grease, and remove any excess grease until an evenly coated, thin film is present.  

  Inspect arcing horns for signs of excessive arc damage and replace if necessary.  

  Check blade lock or latch for adjustment.  

  Inspect all live parts for scarring, gouging, or sharp points that could contribute to excessive radio noise 

and corona. Check corona balls and rings for damage that could impair effectiveness. 

  Inspect interphase linkages, operating rods, levers, bearings, etc. to assure that adjustments are correct, 

all joins are tight, and pipes are not bent.  

  Check for simultaneous closing of all blades and for proper seating in the closed position.  

  Inspect and check all safety interlocks while testing for proper operation.  

Periodic Inspection and Maintenance (10 year) 

 
 
 

  Follow instructions for 5-year Routine Inspection and Maintenance 

 

   

The disconnect switch must be de-energized, disconnecting from all electrical power sources 

before servicing

 

   

The disconnect switch must be de-energized, disconnecting from all electrical power sources 

before servicing.
