Cable in Raceway Art. 817.02 Immediately after placement, the cable ends shall be sealed to prevent entrance of moisture and contaminates, unless splicing or termination work is performed concurrently. Where plowed, the unit duct shall be laid in place and the duct shall not be pulled through the length of the cut behind a bullet-nose mandrel or similar apparatus. Plowing operations shall be non-injurious to the duct. Before final wire and cable connections are made, the Contractor shall demonstrate that all conductors within the unit duct are free to move. When placed in a raceway, lubricating compounds shall be used where necessary to ensure smooth installation.
816.04 Method of Measurement. The unit duct will be measured for
payment in feet (meters) in place. Measurements will be made in straight lines between changes in direction and to the center of equipment and boxes. 3 ft (1 m) of extra unit duct will be allowed when terminating at a controller, light pole, or handhole. 1 ft (300 mm) of extra unit duct will be allowed at pull boxes, junction boxes, and similar locations. The vertical distance of unit duct required for breakaway devices, barrier walls, concrete pedestals, etc., and the depth of any burial will be measured in feet (meters). Changes in direction shall assume perfect straight line runs, ignoring actual raceway sweeps.
816.05 Basis of Payment. This work will be paid for at the contract unit price
per foot (meter) installed for UNIT DUCT, 600V, of the number, size and type of conductors, and the size and type of duct specified. SECTION 817. CABLE IN RACEWAY
817.01 Description. This work shall consist of furnishing and installing
electric cables in raceways, complete with all splicing, identifications, and terminations.
817.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Conductors (Note 1) .......................................................................... 1066.02
b.Cable Insulation .................................................................................. 1066.03
c.Splicing and Termination of Electric Cable ........................................ 1066.06
d.Wiring Identification Markers ............................................................. 1066.07
e.Electrical Tape ................................................................................... 1066.08 Note 1. Copper conductors shall be used. Art. 817.03 Aerial Cable for Lighting CONSTRUCTION REQUIREMENTS
817.03 Installation. Cable shall be installed without damaging the insulation.
Cable lubricant shall be used when pulling cables into conduits. The lubricant shall be non-injurious to conduits, conductors, insulations, or jackets. Where a number of cables are trained through a box, manhole, or handhole, the cables shall be grouped by circuit where applicable and bundled using appropriate cable ties and supported to minimize pressure or strain on cable insulation. Wire and cable extended to light poles shall be of a length sufficient for cable splices to be withdrawn a minimum of 18 in. (450 mm) out of pole handholes. Wire and cable shall not be bent to a radius less than the manufacturer’s recommended bending radius, either in permanent placement or during installation. Cable pulling apparatus shall have no sharp edges or protrusions which could damage cables or raceways. The cable shall be installed directly from the reels on which the cable was shipped. Dragging or laying cable on the ground will not be permitted. The cable shall be installed in continuous spans between terminal points and splicing will only be permitted in pole handholes or junction boxes on bridge structures above grade. Immediately after placement, the cable ends shall be sealed to prevent entrance of moisture and contaminates, unless splicing or termination work is performed concurrently.
817.04 Method of Measurement. The cable will be measured for payment in
feet (meters) in place. Measurements will be made in straight lines between changes in direction and to the center of equipment and boxes. 3 ft (1 m) of extra cable will be allowed when terminating at a controller, light pole, or handhole. 1 ft (300 mm) of extra cable will be allowed at pull boxes, junction boxes, and similar locations. The vertical distance of cable required for breakaway devices, barrier walls, concrete pedestals, etc., and the depth of any burial will be measured in feet (meters). Changes in direction shall assume perfect straight line runs, ignoring actual raceway sweeps.
817.05 Basis of Payment. This work will be paid for at the contract unit price
per foot (meter) installed for ELECTRIC CABLE IN CONDUIT, 600 V of the type, size, and number of conductors specified. SECTION 818. AERIAL CABLE FOR LIGHTING
818.01 Description. This work shall consist of furnishing, installing and
connecting aerial cable complete with all splicing, identifications, and terminations. Aerial Cable for Lighting Art. 818.05
818.02 Materials. Materials shall be according to the following.
Item Article/Section
a.Conductors (Note 1) .......................................................................... 1066.02
b.Aerial Cable Insulation .............................................................. 1066.03(a)(3)
c.Aerial Cable Assembly ....................................................................... 1066.04
d.Splicing and Termination of Electric Cable ........................................ 1066.06
e.Wiring Identification Markers ............................................................. 1066.07
f.Electrical Tape ................................................................................... 1066.08 Note 1. Aluminum conductors shall be used. CONSTRUCTION REQUIREMENTS
818.03 Installation. The luminaire connections to the aerial cable shall be
made with listed parallel tap insulation piercing connectors. The connector shall be rated for 600 V. When the installation is temporary, upon written request of the Contractor, the Engineer may permit temporary portions of the work to be wired with previously- installed (used) aerial cable of ampacity equivalent to the specified cable and of a type and condition approved by the Engineer. The cable shall be left in place for the duration of the need for temporary wiring. In addition to the wiring of temporary equipment indicated, the Contractor shall furnish and install electric feeders and make necessary equipment modifications to connect the existing system(s) to the temporary system(s). Buck-Boost Transformer(s), when indicated on the plans, shall be of the voltage and KVA indicated (or otherwise as applicable for the circuit), dry type, suitable for outdoor installation.
818.04 Method of Measurement. The aerial cable will be measured in feet
(meters) in place and will be taken as the length of the messenger wire. Measurements will be made in a straight line between changes in direction and to the centers of light standards and control cabinets. Sag of the aerial cable or vertical cable will not be measured for payment. When the Engineer requests the used temporary cable be replaced with new, the new cable will be measured for payment. Used aerial cable will not be measured for payment. The rewiring to facilitate relocation of the cable due to staging or other construction requirements will not be measured for payment.
818.05 Basis of Payment. This work will be paid for at the contract unit price
per foot (meter) for AERIAL CABLE WITH MESSENGER WIRE, of the number and size of conductors specified.
