power distribution equipment along with the associated hazards
that may be involved. This publication is written only for such
qualified persons and is not intended to be a substitute for
adequate training and experience in safety procedures for this
type of equipment. Proper installation is the responsibility of the
operating and construction personnel and the utility performing
and authorizing the work. Completion of these instructions implies
no further warranty by the manufacturer.
A Qualified Person is defined in the National Electrical Code
(NEC/NFPA-70) as:
One who has skills and knowledge related to the construction
and operation of the electrical equipment and installations and
has received safety training to recognize and avoid the hazards
involved.
The specific electrical safety training requirements to be
considered a qualified person are detailed in NFPA-70E, Article
110.1(D), Employee Training. Some of the requirements from the
2012 edition are shown in the adjacent column. For the specific
detailedtrainingrequirementsfora Qualified Person make certain
to refer to the most recent applicable edition.
These training requirements would include, but are not limited,
to the following key points:
• The skills and techniques necessary to distinguish exposed
energized parts from other parts of electrical equipment.
• The skills and techniques necessary to determine the proper
approach distances corresponding to the voltages to which the
qualified person will be exposed.
• Theproperuseofthespecialprecautionarytechniques,personal
protective equipment, insulating and shielding materials, and
insulated tools for working on or near exposed energized parts
of electrical equipment.
• Tasks performed less often than once per year have additional
training requirements.
These instructions are intended only for such qualified persons.
They are not intended to be a substitute for adequate training
and experience in safety procedures for this type of equipment.
Additionally, the recommendations in this instruction bulletin are
not intended to supersede or to take the place of established
utility safety guidelines and established practices. If there is any
question, consult with your foreman or supervisor, as appropriate.
Please refer to OSHA 29 CFR 1910.399 and NFPA 70E Articles 100

1. Disconnect, isolate, test for voltage and ground all
connections to the unit in accordance with user's
standard operating procedures and safety practice.
2. Remove the enclosure roof in accordance with the
procedures set forth in Federal Pacific Instruction
Bulletin IB-2A-810. See Figure 1.
3. Open all fuse panels, following standard practices
and procedures set forth in Federal Pacific Instruction
Bulletin IB-2A-210. Opening all the fuse panels will
provide additional space to allow an individual to enter
the isolated medium-voltage compartment and access
any barrier that has been dislodged. See Figure 2.
4. Do not enter the medium-voltage compartment if there
is any chance that debris or moisture from clothing or
footwear may be left on any interior component.
5. When entering the enclosure, DO NOT step on (even
momentarily) any interior component such as bus,
insulators, bushings or bushing wells. Otherwise,
damage may occur that is not immediately observed
or obvious. So, make certain that foot placement is to
the galvanized-steel floor plate.
6. Using 2-inch wide masking (or blue) tape, secure all the
switch inner-phaseandendbarriers(except thedisplaced
barrier) in relative position on the switch by placing one
end of the tape on the top flange of the enclosure and by
placing the other end of the tape along the edge of the
barrier, overlapping the tape onto the sides of each barrier.
Figure 1. Dead-front Pad-mounted PSE Switchgear Unit, with doors
open and secured with wind-braces.
Figure 2. Open fuse panels to provide additional space to allow entry
into the interior of the high-voltage compartment.
Figure 3. Secure each switch barrier in place by applying 2"
masking tape from the top flange of the enclosure (see Figure 3A)
to the edge of the barrier, overlapping the tape on the sides of each
barrier (see Figure 3B).

DANGER
Thefollowingproceduremustbe performed with the unit
completely de-energized, grounded, and isolated from
voltage in accordance with applicable work practices
and safety rules. Any attempt to perform this procedure
with the unit energized may result in electrical arc flash
that can cause equipment damage, personal injury or
death.
Before working on the switchgear, ensure that the
switchgear and incoming and outgoing cables are de-
energized,testedforvoltage,andgroundedinaccordance
withappropriateuser'ssafetyandoperationalprocedures.
CAUTION
Wearappropriatepersonal protection equipment (PPE),in
accordance with applicable user's safety and operating
procedures,when removing,repositioning,andinstalling
the roof.

7. Note the position and location of the switch barriers in
the slots on the switch frame and along the fiberglass
barrier-support angle. See Figure 4. At both ends of
the slotted barrier-support angle, loosen (to the extent
possible, but do not remove) the hardware (using the
1/2" and 9/16" ratchet or box wrenches) that secures
the fiberglass angle to its barrier-support bracket. See
Figure 5. DO NOT loosen the hardware that secures the
bracket to the stud on the enclosure side wall.
8. Withtheswitchbarriers taped in positionandthebarrier-
guide support angle adequately loosened, remove the
displaced barrier. If still necessary to gain additional
flexibility, the hardware may be removed and retained.
Figure 6. Insert the two tabs on the switch barrier into corresponding slots in the switch frame and insert the slot in the switch barrier into the
slot on the fiberglass barrier support angle.
9. Re-install the barrier that was displaced and, if desired,
apply tape (as was done for the other barriers) to secure
itinposition,makingcertaintoinstallthebarrierwith the
tab on the top-front edge of the barrier into the top slot
on the switch frame; the tab on the bottom-front edge
of the barrier into the appropriate slot on the bottom
angle of the switch frame; and the slot on the top-rear
edge of the barrier into the slot on the fiberglass barrier-
support angle. Refer to an adjacent switch barrier that
is already installed to establish appropriate installation
and positioning of the switch barrier into the switch
frame and barrier-support angle. See Figure 6.
Figure 4. Note how the tab, corner and edge of each
switch barrier nests in the appropriate slots in the switch
frame and fiberglass barrier support angle.
Figure 5. Loosen the hardware that secures the
fiberglass angle to the barrier support bracket at each
end.

10. Starting with the barrier on one side, make certain that
everyswitchbarrieris properlyinstalledinitsappropriate
slots.
11. With all switch barriers correctly positioned, re-install
any hardware that was removed and retighten the
hardwareto secure the fiberglass barrier-supportangle
to its mounting-support brackets.
12. Remove the masking tape from all barriers. Do not leave
any pieces of the tape (or the adhesive) on the barriers.
Make certain to remove any debris that may have
inadvertentlyenteredthemedium-voltagecompartment.
13. Replace any gasket around the top of the enclosure that
may have been damaged when the roof was removed.
It is important that the roof gasket adequately seal to
the roof at all locations to avoid entry of any airborne
contaminants or moisture.
14. Re-install the roof as described in IB-2A-810.
