able on-the-line service and to make installation, operation
and maintenance as simple as possible. Federal Pacific PMDF
models meet applicable industry standards, which are ANSI 386
and IEEE C57.12.28.
High quality materials and careful workmanship have been com-
binedtoprovidethebestswitchgearavailable. Theswitchgearhas
been thoroughly inspected and adjusted at the factory. However,
successful operation depends on proper installation and care.
This manual has been written to assist you in obtaining long and
economical service from your switchgear.
Readthismanualbeforeinstallingandoperatingyourswitchgear.
Receiving
Upon receipt of the switchgear, check each item received for
shipping damage. Each item should be checked against the ship-
ping manifest to assure that the proper number of items were
received. Should any shortage or damage exist, note it on the
shipping papers. A claim should be filed at once with the carrier
and the Federal Pacific agent or sales office should be notified.
The carrier is responsible for all damage occurring during tran-
sit. Receiving personnel must note all damage to equipment on
shipping papers so that claims can be processed.
Handling
Removable lifting plates are provided to allow the use of hooks to
lift the complete enclosure. The lifting device should be arranged
to evenly distribute the lifting force between the lifting plates.
Do not lift at an angle less than 60° from the horizontal. See
Figure 2. A spreader bar may be required to maintain the proper
minimum angles. Failure to comply with this requirement may
result in damage to the equipment.
The switchgear is securely mounted to a sturdy shipping pallet
with provisions for forklift use. The use of a forklift truck is not
recommended, but if this method is used the forks must extend
completely through the skid to avoid damaging the equipment.
Storage
The switchgear as received may be wrapped in a protective
plastic film, which must be removed for storage.
To avoid damage to the enclosure finish, the protective film
must be removed for outdoor storage of unit.

Bushing Wells and Bushings
Federal Pacific PMDF Pad-Mounted Switchgear is furnished
with a choice of either 200 ampere bushing wells or 600 ampere
bushings on the line side or load side. The bushing wells and
bushings meet ANSI 386 standard requirements.
Bushing Wells
The 200 ampere bushing wells accommodate 200 ampere elbow
(separableinsulated)loadbreakconnectors and accessories. The
units are shipped with a yellow dust cover over each bushing well
to preventcontamination. Dust covers are NOT capable of provid-
ing any electricalinsulationat medium voltage levels.Therefore,
if an elbow is not to be connected to a bushing well, prior to
energization the dust cover MUST be removed and replaced
with an insulating protective bushing-well plug. See Figure 6.
Install load-break inserts following the insert manufacturer’s
instructions supplied therewith. Terminate cables and install 200
ampereloadbreakelbowsandaccessoriesfollowinginstructions
provided by the cable manufacturer and the elbow manufacturer.
The 200 ampere elbows are a loadbreak device and, if standard
system operating practices and conditions permit, may be re-
moved when the equipment is energized, providing single-pole
loadbreak live switching is performed using insulated shotgun
clamp sticks. Before performing any live-switching with elbows,
install insulating feed-through standoff bushings on the parking
stand adjacent to the loadbreak elbow to be switched.
WARNING
For all un-terminated phase positions, failure to remove dust
covers and replace with a protective insulating bushing-well
plug prior to energization may result in equipment damage,

is energized.
Always follow user’s and manufacturer’s standard operating
procedureswhen installing, maintainingor removing 200 ampere
loadbreak elbow connectors and accessories. Such procedures
should always include:
1. Verifying the correct circuit is being maneuvered,
2. Installing portable feed-through standoff bushings on the
parkingstandadjacenttotheloadbreakelbow tobe switched,
3. Recognizing that the unit may be subject to back feed and
taking necessary precautions to isolate the equipment from
such possibility before maneuvering 200 amp elbows when
dead-break procedures are to be followed,
4. Testing for voltage, and
5. Grounding the circuits before any other work is attempted.
Bushings
The 600 ampere bushings accommodate 600 ampere elbow
(separable insulated) connectors and accessories. The units
are shipped with a red dust cover over each bushing to prevent
contamination. Dust covers are NOT capable of providing any
electrical insulation at medium voltage levels. Therefore, if an
elbow is not to be connected to a bushing, prior to energization
the dust cover MUST be removed and replaced with an insulating
protective bushing cover.
Always follow user’s and manufacturer’s standard operating
procedureswheninstalling,maintainingorremoving600 ampere
elbow connectors. Such procedures should always include:
1. Opening adjacent load-interrupting devices to completely de-
energize the unit,
2. Recognizing that the unit may be subject to back feed and tak-
ing necessary precautions to isolate the equipment from such
possibility before maneuvering 600 amp elbows,
3. Testing for voltage to verify circuit is de-energized before
maneuvering 600 amp elbows, and
4. Grounding the circuits before any other work is attempted.

3. System operating practices may allow loadbreak elbows to
be switched while the associated cable is energized. Follow
loadbreak elbow manufacturer’s procedures for proper tech-
nique whenlive switchingisto beperformedusing theelbows.
If live switching is not permitted with elbows, appropriately
rated voltage testers should be used to verify that the circuit
is completely de-energized.
4. Using the shotgun clamp stick, install and secure the feed-
through standoff bushing on the parking stand.
5. If live switching of elbows is not permitted for operating
circumstances of the system, test the elbow to be moved for
voltage. After verifying that voltage is not present, or if live
switching is permitted, use the shotgun clamp stick to remove
the elbow connector from the appropriate bushing well, fol-
lowing standard system operating procedures and the elbow
manufacturer’s instructions. Move the elbow connector onto
a standard feed-thru standoff bushing that is placed in the
parking stand.

Door System
The door latching feature furnished on the main doors provides
ease in opening and closing of the doors.
Door-Latch Features
Features of the door-latch system are:
• Three-point latching of doors. See Figure 12.
• After unlatching on opening, the door is secured open with
a windbrace. Hinged inner barriers are secured open with
a cable-connected pin on the door and inserted into a clip
on the top edge of the barrier. See Figure 12. For closing, the
door is manually latched, bolted closed and padlocked.
• Unlatching is only accomplished by first rotating (in counter-
clockwise direction) the captive penta-head (or hex-head)
bolt through several revolutions and then lowering the door
handle. See Figures 8 through 10.
Figure 13. Padlock cannot be inserted until
penta-head bolt is fully tightened.
Figure 14. Always close, latch and padlock
the enclosure door before leaving the unit or
when working on the opposite side.
Figure 10. Door handle cover is secured
closed by a penta-head (or hex-head) bolt.
Turn socket counter-clockwise to loosen
bolt.
Figure 9. Door handle is stainless steel. Figure 11. With penta-head bolt fully
loosened, handle can be pivoted down to
unlatch the door.
Figure 12. Three-point door latch
mechanism. Enclosure door is
secured open by windbrace. Inner
barrier is secured open by a pin on
the door inserted into a clip on the
barrier.
• The door padlocking provision prevents unlatching the door-
latch cover until the padlock has been removed. Padlocking
also secures the door to the cabinet enclosure. See Figures
13 and 14.
• The protective door-latch cover is stainless steel. Also, ac-
cess to the penta-head bolt is only possible after the padlock
has been removed.
• A closed, latched and padlocked door can successfully
withstand a "pull" greater than 600 pounds at any point on
the door.
