This division is for methods, materials and equipment to construct and put in working
order the proposed lighting; however, every fitting, minor detail, or feature may not be
shown or described. The Contractor shall be an expert in the trade, capable of
understanding the intent of the contract and constructing the lighting and electrical system(s)
in accordance with the best practice of the trade.
The Contractor actually performing the work described in the contract shall have
a license of the proper classification from the North Carolina State Board of Examiners of
Electrical Contractors.
Have the licensed contractor available on the job site as necessary when work is being
performed or when requested by the Engineer. Have this contractor maintain a set of project
plans and Specifications in his possession on the job site and a set of accurate as built plans.
This contractor shall be qualified to responsibly instruct and direct all employees regarding
the electrical work.

MATERIALS
(A)
General
All materials used in the work are to be new materials unless noted elsewhere in the
contract. References in the contract to any proprietary device, product, material,
fixture, form, type of construction, etc. by make or catalog number, with or without
the words or approved equal, is to be taken as establishing a standard of quality, and
is not to be construed as limiting competition. In such case, the Contractor may use
any material, equipment or type of construction which has written approval as being
an acceptable equal to that named for the particular use intended by the contract.
Provide materials that are labeled or listed by an acceptable organization, which is
defined as an organization that maintains periodic inspection of the production of the
materials and verifies, by the labeling or listing procedure, that the materials comply
with appropriate standards of performance or are suitable for use in a specified
manner. Provide Underwriters' Laboratories (UL) labeled and listed materials when
such labeling and listing is available for such materials.
Make sure that materials are in compliance with requirements for use of domestic
products, as specified in other sections of the Specifications. Section 1400
14-2
(B)
Conduit
Use conduit and duct that is either metallic (Rigid Metallic Conduit) or non-metallic
(Polyvinyl Chloride or High Density Polyethylene), as noted on the plans and as
described in Section 1098-4.
(C)
Wire
Use stranded copper conductors unless specifically noted otherwise on the contract.
Use wire and cable which conforms to IPCEA specifications and has marks for
identification (manufacturer's name, type insulation, and gauge of conductor) and the
UL label.
Use wire insulation rated at 600 VAC or greater.
Use the following types of wiring unless noted otherwise on the plans:
Service Lateral
UL Type USE
Control System
UL Type THW or RHW or THHN
Feeder Circuits in Conduit
UL Type USE
Branch Circuits in Light Standards
UL Type NM Cable
Equipment Grounding Conductor
Solid MHD, Bare or Insulated
Grounding Electrode Conductor
ASTM B-2
Feeder circuits in conduit with #8 conductors and smaller may consist of a cable
assembly rated UL Type UF. Use #6 AWG for the grounding electrode conductor
unless noted larger on the plans.
(D)
Grounding and Bonding Equipment
Use Ground Rods which are 5/8" diameter x 8' copper clad steel and which have
a one piece silicone bronze clamp with a socket or hex head screw. Make sure that
all grounding and bonding equipment conforms to UL Standard 467, Electrical
Grounding and Bonding Equipment.
(E)
Fuseholders
Provide fused overcurrent protection in the base of each light standard, and other
locations as noted. Use a fuseholder that is rated 600 VAC, 30 amp minimum,
waterproof, and constructed so that the fuse will be disconnected from the line side
power every time the fuseholder is opened. It may be made of molded plastic or
rubber and have insulating boots. Use terminals which are specifically rated for the
size and number of conductors required.
Use fuses which have 5000 amp minimum interrupting capacity at the supply
voltage, are rated 10 amp or as noted on the plans, and are not glass type unless
specified different in the contract. Use the same type fuse in all fuseholders on
a project unless specified differently at specified locations. Section 1400
14-3
Use fuseholders that have been specifically designed as breakaway devices in
fiberglass standards and standards with breakaway bases. Use fuseholders that have
been designed to disconnect line side power without damage to the terminals or
conductors every time sufficient pulling force is placed on the line and load side
conductors.
(F)
Hardware
Use mounting or attachment hardware including bolts, nuts, washers, straps, clamps,
and hangers which is made of stainless steel, hot dipped galvanized or of equal
corrosion resistance. Use bolts, which are minimum length and are not less than
1 nominal size smaller than the opening being utilized.
(G)
Lamps
Use lamps that conform to ANSI specifications, are of the type and wattage indicated
on the contract, are rated for a minimum of 24,000 hours life, have a mogul base, and
have special coatings for premium efficiency and color rendition. Clearly mark the
installation date on the base. Provide and install lamps for all luminaires furnished
on the project.
(H)
Duct and Conduit Sealer
(1)
Use duct and conduit sealer or mastic which is a putty-like compound and:
(2)
is permanently non-hardening, non-oxidizing, and non-corrosive to metals,
rubber, plastic, lacquer and paints,
(3)
is readily workable for thumbing into openings and forming into seals around
wires inside conduits and openings around conduits,
(4)
has a service temperature range of minus 30
°F to 200°F
(5)
is clean, non-poisonous and non-injurious to human skin,
(6)
seals against water, dust and air and shall adhere to wood, glass, plastics,
metal, rubber, and painted surfaces.
(I)
Pull Lines
Place pull lines specifically designed for pulling a rope in all empty conduits and
electrical duct so that electrical circuits can be installed in the future. Use pull lines
which are 2 ply with a tensile strength of 240 pounds minimum and resistant to
tangling, rot, and mildew.
1400-3
SUBMITTALS
(A)
Catalog Cuts
Submit for approval catalog cuts and/or shop drawings for materials proposed for use
on the project. Allow 40 days for review of each submittal. Do not deliver materials
which have not been approved to the project. Submit 8 copies of each catalog cut
and/or drawing and show for each the material description, brand name, stock-
number, size, rating, manufacturing specification and the use for which it is intended. Section 1400
14-4
Three copies of approved submittals will be returned to the Contractor. Present
a catalog cut or drawing for all components of each contract item. Present the
submittals neatly arranged in the same order as the contract bid items.
(B)
Certifications
In accordance with Article 106-3, furnish a Type 3 - Manufacturer's Certifications for
light standards, high mounts and lowering devices and a Type 6 - Supplier's
Certifications for conductors. Submit certifications when the above materials are
delivered to the project.
Type 3 or Type 6 Certifications may be requested for any or all of the other material
which does not have a name plate showing sufficient information to verify that the
material was manufactured to the requirements of these Specifications.
(C)
Samples
Random samples will be taken of the various items for the purpose of verifying
conformance with Specifications. The selection of the items to be sampled and the
taking of the samples will be done by the Engineer.
Failure to meet specification requirements by 2 samples of any material will be
sufficient reason for rejection of all materials from the same lot.
Upon request, there will be reimbursement for the actual verified cost of such
material taken as samples, including any handling charges less any discount allowed
on the invoice, but with no percentage added, and such material will thereafter
become the property of the Department.
(D)
As-Built Plans
Submit two complete sets of as-built plans for review upon completion of the work,
showing the location of all buried electrical circuits, with pavement crossings
dimensioned from fixed objects or from survey stations.
Include in the as-built plans the title (No. 1), index (No. 1A), summary
