CITY OF VERNON LIGHT AND POWER
PADMOUNT SWITCH
TECHNICAL REQUIREMENTS
(a) Full coverage at joints and blind areas shall be achieved by processing
enclosures independently of components such as doors and roofs before
assembly into the unitized structures.
(b) All exterior seams shall be filled and sanded smooth for neat appearance.
(c) To remove oils and dirt, to form a chemically and anodically neutral
conversion coating to improve the finish -to -metal bond, and to retard underfilm
propagation of corrosion, all surfaces shall undergo a thorough pretreatment
process comprised of a fully automated system of cleaning, rinsing,
phosphatizing, sealing, drying, and cooling before any protective coatings are
applied. By utilizing an automated pretreatment process, the enclosure shall
receive a highly consistent thorough treatment, eliminating fluctuations in
reaction time, reaction temperature, and chemical concentrations.
(d) After pretreatment, protective coatings shall be applied that shall help
resist corrosion and protect the steel enclosure. To establish the capability to
resist corrosion and protect the enclosure, representative test specimens coated
by the enclosure manufacturer's finishing system shall satisfactorily pass the
following tests:
(1) 4000 hours of exposure to salt -spray testing per ASTM B 117 with:
(i) Underfilm corrosion not to extend more than 1/32" from the scribe as
evaluated per ASTM D 1645, Procedure A, Method 2 (scraping); and
(ii) Loss of adhesion from bare metal not to extend more than 1/8" from the
scribe.
(2) 1000 hours of humidity testing per ASTM D 4585 using the Cleveland
Condensing Type Humidity Cabinet with no blistering as evaluated per ASTM D
714.

CITY OF VERNON LIGHT AND POWER
PADMOUNT SWITCH
TECHNICAL REQUIREMENTS
(7) 3000 cycles of abrasion testing per ASTM 4060 with no penetration to the
substrate.
Certified test abstracts substantiating the above capabilities shall be furnished
upon request.
(e) After the finishing system has been properly applied and cured, welds
along the enclosure bottom flange shall be coated with a wax -based
anticorrosion moisture barrier to give these areas added corrosion resistance.
(f) A resilient closed -cell material, such as PVC gasket, shall be applied to
the entire underside of the enclosure bottom flange to protect the finish on this
surface from scratching during handling and installation. This material shall
isolate the bottom flange from the alkalinity of a concrete foundation to help
protect against corrosive attack.
(g) After the enclosure is completely assembled and the components
(switches, fuses, bus, etc.) are installed, the finish shall be inspected for scuffs
and scratches. Blemishes shall be touched up by hand to restore the protective
integrity of the finish.

4.01 Interrupter Switches
Interrupter switches shall have a two-time duty -cycle fault -closing rating equal to
or exceeding the short-circuit rating of the padmount switch. These ratings
define the ability to close the interrupter switch twice against a three-phase fault
with asymmetrical current in at least one phase equal to the rated value, with the
switch remaining operable and able to carry and interrupt rated current. Tests
substantiating these ratings shall be performed at maximum voltage with current
applied for at least 10 cycles. Certified test abstracts establishing such ratings
shall be furnished upon request.
(b) Interrupter switches shall be operated by means of an externally
accessible 3/4" hex switch -operating hub. The switch -operating hub shall be
10 of 17

mounted gear enclosure and shall accommodate a 3/4" deep -socket wrench or a
3/4" shallow -socket wrench with extension. The switch -operating -hub pocket
shall include a padlockable stainless -steel access cover that shall incorporate a
hood to protect the padlock shackle from tampering. Stops shall be provided on
the switch -operating hub to prevent overtravel and thereby guard against
damage to the interrupter switch quick -make quick -break mechanism. Labels to
indicate switch position shall be provided in the switch -operating -hub pocket.
(c) Each interrupter switch shall be provided with a folding switch -operating
handle. The switch -operating handle shall be secured to the inside of the switch -
operating -hub pocket by a brass chain. The folded handle shall be stored behind
the closed switch -operating -hub access cover.
(d) Interrupter switches shall utilize a quick -make quick -break mechanism
installed by the switch manufacturer. The quick -make quick -break mechanism

open and close the interrupter switch independent of the switch -operating -hub
speed.
(e) Each interrupter switch shall be completely assembled and adjusted by
the switch manufacturer on a single rigid mounting frame. The frame shall be of
welded steel construction such that the frame intercepts the leakage path which
parallels the open gap of the interrupter switch to positively isolate the load circuit
when the interrupter switch is in the open position.
(f) Interrupter switch contacts shall be backed up by stainless -steel springs to
provide constant high contact pressure.
(g) Interrupter switches shall be provided with a single blade per phase for
circuit closing including fault closing, continuous current carrying, and circuit
interrupting. Spring -loaded auxiliary blades shall not be permitted. Interrupter
switch blade supports shall be permanently molded in place in a unified insulated
shaft constructed of the same cycloaliphatic epoxy resin as the insulators.
(h) Circuit interruption shall be accomplished by use of an interrupter which is
positively and inherently sequenced with the blade position. It shall not be
possible for the blade and interrupter to get out of sequence. Circuit interruption
shall take place completely within the interrupter, with no external arc or flame.
Any exhaust shall be vented in a controlled manner through a deionizing vent.
(i) Interrupter switches shall have a readily visible open gap when in the open
position to allow positive verification of switch position.
