SECTION IB-2B-800
INSPECTION & MAINTENANCE RECOMMENDATIONS
DEAD-FRONT PAD-MOUNTED SWITCHGEAR TYPE PSE
JUNE 2021, REV. 1.1
Page 2
Barriers, viewing windows and insulators can be cleaned with a non-
alcohol and non-solvent based cleaner that does not leave any residue
when dry. Residue must be removed.
3. Exercising
Yearly mechanical exercising of the switch is recommended. Refer to
Instruction Bulletin Section IB-2A-210 for information on operating
the switch.
Current carrying parts must be completely de-energized from all
sources before any maintenance is performed on these parts. Follow
normal system operating practices to de-energize, test for voltage
and ground these parts before any work is performed.
4. Exercise Fuse Mountings
Open and close hinged fuse panels and insure proper latching
as described on the label on the inside of the compartment door
and in Instruction Bulletin Section IB-2A-210. Inspect fuse contact
interfaces for damage and overheating, which will be evidenced
by distortion or discoloration of the contacts. Note that contacts are
copper and may be silver plated. There will be normal oxidation of
these parts. Slight irregularities can be burnished with an emery
cloth or paper.
5. Replacement Parts
If parts or labels are required they may be ordered by contacting Federal
Pacific at 276-669-4084 or your local Federal Pacific Manufacturer's
Representative. A directory of the representatives can be found at www.
federalpacific.com. If parts are ordered, the unit serial number and date
of manufacture must be provided along with the part description.
6. Maintaining the Exterior
The exterior finish can be maintained by periodic washing, touch up
of any scratches and abrasions, and waxing.
For areas to be touched-up, clean the area removing all rust. Apply a
red-oxide primer, available in spray cans from a local paint supplier
or home improvement store. Spray cans of the topcoat finish are
available from Federal Pacific (specify the original color).
7. Verify Security Devices
Verify the operational integrity of security devices such as door
latches, penta-head bolts, hinges and key-interlock systems. Make
certain padlocks are properly installed on all doors and covers.
1. Switch Operation
Check switch for proper operation refer to Instruction Bulletin
IB-2A-210. If the switch is closed on a short circuit within the fault
closing rating and the short circuit is cleared by circuit breakers or
fuses, the switch will not sustain damage which would require major
repairs. However, the switch should be inspected before returning to
service to determine switch condition. See Lubrication.
2. Cleanliness
Check for cleanliness generally, but particularly for accumulation of
any foreign material on insulators, barriers and viewing windows.
The procedures required for operation of the Federal Pacific Auto-jet

II
Load-Interrupter Switches, the dead-break hinged fuse panels, the doors,
the barriers and other accessory components are covered in detail in the
Federal Pacific Instruction Bulletin Section IB-2A-210. The inspection and
maintenance recommendations covered in this bulletin are expected to
be performed in conjunction with a review of IB-2A-210. This bulletin
does not cover all the detailed and specific operational procedures and
checks. In addition, these instructions are not intended as a substitute for
the user’s standard operating practices and procedures. A copy of Instruc-
tion Bulletin Section IB-2A-210 can be printed from the internet at www.
federalpacific.com.
When cleaning components, NEVER use any industrial strength cleaners.
NEVER apply lubricants to the probe contact or the tulip contact which
are the interrupting contacts. NEVER use any solvent-based or flammable
products on any components in the pad-mounted switchgear. Solvents
and flammable products can attack non-metallic components of the
equipment and reduce electrical and mechanical properties.
Maintenance
Federal Pacific switchgear does not require routine mechanical or electri-
cal maintenance. However, the following are some recommendations for
enhancing continued service of the equipment.
NOTICE
WARNING
WARNING
Before Opening the Switchgear
The following inspection and maintenance procedures must be
performed with the current-carrying parts completely de-energized
and isolated from voltage. Any attempt to perform the inspection and
maintenance with the current-carrying parts energized may result in
electrical arc flash that can cause equipment damage, personal injury
or death.
DANGER
CAUTION
Do not put any lubricant on switch probe or puffer contacts. Refer to sec-
tion "10. Lubrication".
