613.01 This work consists of furnishing and installing foundations, light standards, luminaires,
light sources, conduit, cable, wiring, and incidental materials for highway lighting and electrical systems per these specifications and in conformance with the details, lines, grades, and locations shown on the plans or established. MATERIALS
613.02 Roadway lighting materials shall conform to Section 715 and shall be compatible with
the requirements of the local agency having jurisdiction.
a.Foundation. Concrete Foundation Pads and Light Standard Foundations shall be cast -in-place concrete. A complete foundation includes the concrete, reinforcing steel, grounding electrode, connector bolts, and anchor bolts. Connector bolts and anchor bolts shall accommodate the anchorage of the light pole from its base flange to the base or transformer base, and from the base or transformer base to the light standard foundation.
b.Light Standard. A complete light standard includes the metal light pole, mast arm or arms, base or transformer base, approved breakaway device (optional), in -use receptacles (optional), grounding system, and all hardware. When a transformer base is not used, the pole sh all have a handhole.
c.Conduit . Conduit includes all junction boxes, pull wire, weatherheads, adaptors, and expansion joints for conduit required to install complete runs.
d.Electrical Warning Tape . Electrical warning tape shall consist of pre- manufactured non - adhesive polyethylene material that is unaffected by acids, alkalis, and other soil components. The tape shall be detectable. The color of the tape shall be red, and it shall be a minimum 3.5 mils thick and 6 inches wide. Its tensile strength shall be 1,750 psi lengthwise. The electrical tape shall include the following identification printed in black letters continuously along the length of the tape: “CAUTION BURIED ELECTRIC LINE BELOW”. The identification note and color of tape shall conform to the requirements of the “American Public Works Association (APWA) Uniform Color Codes (Red) – Electrical Power Lines, Cables, Conduit and Lighting Cables”.
e.Luminaire. A complete luminaire includes the housing, lens, Light Emitting Diode (LED) board, dimming driver , slip- fitting clamp or approved manufacturer mounting, all necessary internal wiring, and 7 -pin photoelectric control receptacle. Luminaires shall operate at either 120 VAC (Volts Alternating Current), 60 Hz, 277 VAC, 60 Hz or 120- 277VAC, 60 Hz.
