(1) General
A. A typical padmounted equipment enclosure consists of a
surrounding case or housing for equipment to prevent
unauthorized access to protect people against accidental
contact of energized parts and protect equipment against
weather hazards. The enclosure is mounted on a pad, above
ground level, and may �*)e ventilated to permit circulation
of air.
B. Entry into the enclosure shall be through either an access
door(s) or hood (s) as specified.
(2) Structural Strength and Integrity Test:
The structural strength and integrity test shall comply
with the latest NEMA Official Standards and ANSI Standards
for testing, design and enclo=Ure security.

(3) Construction
A. The construction shall be such that:
1. It prevents the entry of foreign objects, such as
sticks, rods, or wires.
2. It inhibits dismantling of the equipment.
3. It is free of areas which could provide access by
forcing techniques.
4. Panels shall be fastened or hinged to resist
disassembly, breaking or prying open from the
outside. Normal entry shall be possible only with
the use of proper access tools. Latches and
other provisions for locking hinged panels shall
be furnished.
5. There -hall be no exposed screws, bolts, or other
fastening or hinging devices which are externally
removable (with the exception of pentahead bolts
provided for extra security) that would provide
access to energized parts of the enclosure.
P. The transformer tank and enclosure shall be constructed
cE minimum 14 gauge steel. The radiator to be constructed
of minimum 18 gauge steel.
C. In addition to the regular locking provisions, all access
doors shall be secured by a recessed, captive, pentahead
bolt which threads into a nut with a blind hole. A pentahead
bolt shall be considered **captive"when the retention
scheme will prevent it from being readily removed during
normal operation of the door(s) of the hood(s). The recess
is to be nonrotating. The dimensions of the pentahead bolt
and nonrotating recess shall comply with Figure 11 of the
ANSI C57.12.26-1975. If all doors can be secured with a
single bolt, one bolt will. be sufficient.

D. Each latched door(s) shall be latched at a minimum of three
points. In addition to the three-point latching, one
pentahead bolt shall be coordinated with the latch and
padlock to prevent unlatching and insertion of the padlock
into the hasp when and until the bolt head is essentially
completely seated, respectively. Low profile cabinets, with
access flip -up hoods, need only padlock and pentahead bolt
provisions, and shall be coordinated to prevent insertion
of the padlock into the hasp until the bolt head is
essentially completely seated.
E. The padlocking device shall be so designed and located a5
to resist prying or breaking off by screwdrivers, wrecking
bars, tire irons, single -socket lug wrenches, or other
readily accessible tools.
F. The edges of the access doors or hoods shall be formed to
provide:
1. A close -fitting mating surface, with internal
insertion -prevention lip that will be shaped to
prohibit entry or prying by screwdrivers, wrecking
bars, tire irons, single -socket lug wrenches, or
other readily accessible tools.
2. A rigid panel which, in conjunction with a handle -
linkage -latching mechanism with three (or more) point
latching, will resist bending in the event that
sufficient force is applied to distort the compartment
or compartment door(s) and permit prying access to the
door edges.
6. Hinge pins shall be passivated AISI (American Institute
of Steel Industries) Type 304 stainless steel or equivalent
corrosion -resistant metal.
H. If a handhole cover is exposed, it shall be secured
against tampering by some means accessible only from
the inside of the compartment.
1. The bottom edge of the enclosure shall provide for
flush mounting on a flat, rigid mounting surface to
prevent wire entry into the compartment.
