49.11
On 600-volt conductor splices of solid or stranded conductor sizes #14 AWG to #6 AWG,
the Contractor has the option to use either crimp-type connectors or spring-type connectors of
three-part construction. The three-part construction shall consist of a zinc-coated free
expanding steel spring enclosed in a steel shell, with an outer jacket of polyvinyl chloride. The
outer jacket shall have a flared skirt, be flexible, and be able to withstand 105°C temperature
continuously. Each splice shall have the spring connector sized in accordance with the
manufacturer's recommendations for the number of conductors and gages being spliced. Wire
strip lengths shall also be in accordance with the manufacturer's recommendations. After the
spring connector has been applied to the connection, the splice shall be coated by submersion
with a corrosive-resistant, solvent-resistant, sealing, bonding and flexible electrical coating,
having at least 100-volt/mil electrical strength. Upon coating of the splice, the flared skirt end
shall be positioned in an upright alignment and maintained in place until the electrical coating is
dry.
The use of heat shrinkable tubing will only be permitted for splicing of detector loop
conductors and detector lead-in cables in accordance with Section 49-5.01.C, “Splicing Details”,
in this Section of these Specifications.
In the handhole section of each luminaire pole, a fused disconnect splice connector shall be
installed in each ungrounded conductor between the line and the ballast.
Luminaires with up to 200-watt bulbs shall have six-amp (6A) fuses installed. Luminaires
with 250 to 400 watt bulbs shall have ten-amp (10A) fuses installed. All fuses shall be midget
ferrule type, rated at 600 volts, and fast blowing.
49-2.10 Bonding and Grounding
Bonding and grounding shall conform to Section 86-2.10, “Bonding and Grounding”, of the
State Specifications, except that paragraph 6 shall not apply, and these Specifications.
For bonding purposes in all non-metallic type conduits, a No. 6 copper wire shall be run
continuously in circuits used for series lighting, and a No. 10 copper wire shall be run
continuously in all other circuits. Where non-metallic conduit is to be installed for future
conductors, a green No. 10 THW copper wire shall be installed in these conduits. Equipment
bonding and grounding conductors are not required in conduits which contain only loop lead-in
cable or signal interconnect cable or both.
Grounding jumper shall be attached by a three-sixteenths inch (3/16”) or larger brass bolt in
the standard or pedestal and shall be run to the metallic conduit, ground rod, or bonding wire in
the adjacent pull box. The grounding jumper shall be visible and accessible after the cap has
been poured on the foundation.
49-2.11 Service
Electrical service installation and materials shall conform to these Specifications.
Each service enclosure (or “can”) shall be fabricated from 14 gauge Type 304D stainless
steel and shall conform to the requirements for cabinets fabricated from stainless steel as
specified in Section 86-3.07A, "Cabinet Construction”, of the State Specifications, and these
Specifications.
The mounting brackets shall be 10 gauge Type 304D stainless steel. All welds shall be of
highest quality and ground smooth and finished so that grind marks are not visible.
