SPECIFICATION
MOUNTING POST AND PEDESTAL
1.
The requirements for utilization of mounting posts and
pedestals are intended for use in accordance with the National Electrical Code,
NFPA 70. The enclosure shall have a 3R rating. The mounting post and pedestal
unit, although not restricted to such use, is intended for outdoor locations
such as:
a.
Repairing damaged or
deteriorated conduit / weatherproof box installations.
b.
Branch circuits to
detached building sites.
c.
Golf courses and support
structures.
d.
Amusement parks and
theme parks.
e.
Commercial malls and
town centers.
f.
Municipal parkways.
g.
Landscaped roadway
median strips.
h.
Receptacles for seasonal
display lighting.
i.
Automatic door switch
mounting posts for handicapped access door operators.
j.
Residential or municipal
gardens.
k.
Decorative ponds; pumps, lighting, and accessory equipment
l.
To compensate for the
results of soil subsidence caused by natural compaction or freeze / thaw cycles
that occurs at any or all of these applications.
m.
Indoors: Power drops for
factory machinery with requirements up to 60 amp, 600volt, 3 phase.
2.
The mounting post and pedestal unit shall be so
constructed and listed by a recognized safety testing laboratory to perform as
a stand alone, self supporting unit, in the ground, or, when used in
conjunction with a mounting bracket, on a flat masonry, or concrete
surface. When used in the ground, and
conditions exist that does not allow for a required minimum depth of 24 inches
below grade, an accessory ground supporting “X” type anchor can be utilized to
maintain a plumb and level installation.
Concrete or other equivalent material can be used to backfill the hole.
3.
The flat surface
mounting type bracket shall be available in a single mounting post or pedestal
supporting bracket configuration, or one available to support two pedestal
units, in a back to back configuration; and also to have a listing with a
recognized safety testing laboratory, for the usage for which it is
intended. Four mounting holes are
provided with each base. A pattern
template is to be available to use preset anchoring bolts or marking of holes
to be drilled for setting anchors.
4.
The mounting post or pedestal unit shall have an
unrestricted bottom opening 5 inches wide by 2 ½ inches deep; incorporating
slots on both sides, that extend up 6 inches, to help in the placement of
underground raceways or direct burial cables.
The conduits or direct burial cables are to extend up into the mounting
post or pedestal unit and not to be
secured to the mounting post or pedestal, or clamped to the mounting post or
pedestal in any manner. Independent
movement of the mounting post and
pedestal must remain free from the
supplying or exiting conduits or direct burial cables at all times.
5.
The mounting post and
pedestal unit shall be so constructed and listed by a recognized safety testing
laboratory to accommodate conduit raceways up to 11/4 inch trade size or #6
direct burial cables.
6.
The mounting post or
pedestal unit shall have the direct burial cables or pulled in wires trained in
appropriate “S” loops to allow for movement of an installed post or pedestal
caused by freezing/thawing cycles, or soil subsidence or compaction to occur
without stressing the wire terminations.
7.
The mounting post or pedestal unit shall have a length
of removable cover on the front side, secured by one mounting screw on the top,
while the bottom of the cover incorporates
an upturned clamping groove mating with a reversed turned down lip
formed on the base of the post or pedestal.
The turned down lip on the base of the post or pedestal unit provides
a rounded corner across to full width
of the unit, and allows for wires to be pulled into their conduits across a
smooth surface.
8.
The mounting post or pedestal unit shall have the
required size opening and screw hole configuration to allow installation of
NEMA style wiring devices and covers, or plates. The “in use” covers can be either plastic or metallic.
9.
The mounting post or pedestal unit shall be available
as a single gang unit, with either a vertical or horizontal oriented device
opening. Two gang models shall also be
available in the vertical oriented device style opening.
10.
The mounting post or pedestal unit shall be available
with a option on all two gang models for a divider running full length from top
to bottom, allowing for separation of services. 600 volt cables and
wiring devices can be separated from voice / data, or other low voltage cabling
and utilization devices.
11.
The mounting posts and pedestals shall be manufactured
using a minimum of .070 cold rolled steel # 1020. The protective coating shall have a 600 hour salt spray rating,
with a 1200 hour moist carbon dioxide, sulfur dioxide, air mixture
exposure. Underwriters Laboratories
specification # MH6892 process shall be the type supplied on both the mounting
posts or pedestal units, and the
mounting brackets, The coating is a cationic epoxy electrocoat, with a
polyester topcoat.
12.
The mounting posts and pedestals shall be optionally
manufactured using a minimum of .070stainless steel # 304 weldable with a 4b
finish.
13.
Grounding of all mounting posts and pedestal units
shall conform with all requirements of the National Electrical Code, or local
building code, that is in use where the units are installed. To facilitate grounding of the mounting
posts and pedestals they are to be supplied and delivered with a 1/4-20 stud, nut, washer, and lug to accommodate
a grounding wire sized from # 14 to # 6. Grounding bushings are to be installed
on all entering and exiting metallic conduits.
Grounding wires are to be pulled in with circuit conductors installed
with plastic conduits or raceways, and are suggested to be pulled in metallic
raceways, along with their circuit conductors.
14.
Mounting posts or pedestals have no prepositioned or
knockout locations provided. Mounting
holes for fixtures or photo cells are to be drilled in the field. Fastening or anchoring holes to anchor the
mounting posts or pedestals to a structure or pole etc shall be field
drilled. Mounting holes in the top of
the mounting post or pedestal for light fixtures or other devices shall be
fitted with a Meyer’s hub, sealing washer, or sealing locknut.
15.
Mounting posts or pedestals are to be mounted a
minimum of 6 inches above grade level. When installed in an area where lawn
maintenance equipment is to be used, an appropriate height level needs to be
determined so covers and devices are safe from damage by mowing and trimming
equipment. Mounting posts or pedestals
are to be available in lengths of 30 inches, 36 inches, 42 inches, 48 inches,
and 54 inches.
