(2)Payment for the Signal Face bid items and Pedestrian Push Butt ons is full compensation for providing

a complete and functioning assembly.

(3)Payment for the Signal Mounting Hardware bid items is full compensation for providing mounting

hardware, including spacers.

Effective with the December 2018 Letting 490 2019 Standard Spec ifications (4) The department will pay for wiri ng from the signal face terminal strip to the underground feeder cables at the top of the concrete base separately under the appropriat e Cable Traffic Signal bid item as specified in 655.5 .

Effective with the December 2018 Letting 491 2019 Standard Spec ifications Section 659 Lighting

659.1Description

(1)This section describes providi ng highway, walkway, and other outdoor lighting.

659.2Materials

(1)Furnish lighting components from the department's QPL.

659.3Construction

659.3.1 General

(1)Keep the luminaires in their sh ipping cartons and protect against contamination until use. Wear clean

gloves when installing luminaires. Provide circuit identificati on plaques and luminaire sequence decals suitable for outdoor constructi on on the support poles as the plans show. 659.3.2 Wiring and Fusing

(1)Use 12 AWG, stranded copper, XLP insulated, single conductor, USE rated, 600 volt AC wire from

pole hand holes to luminaires, unless sized other wise on the pl ans.

(2)For fusing in transformer bases, hand-holes, or junction boxes , install fuse holder assemblies from a

department-approved manufacturer. Use in-line 600 volt AC break away fuse holder assemblies with waterproof insulating boots and mi dget 13/32-inch by 1 1/2-inch time delay fuses. Fuse as follows: - Use 600 or 500 volt AC rated fuses for 480/240 volt systems. - Use 250 volt AC rated fuses for 240/120 volt systems. - If luminaires are double-fused in 240 volt AC 2-wire systems, or 480 volt AC 3-phase delta systems, use two-pole fuse holders.

(3)Individually fuse the luminaires at 5 amp unless the plans show otherwise. Locate fusing at the pole

hand-hole. Fuse walkway lighting units at 5 amp, in the hand-hole of the pole. Fuse underdeck lighting at 5 amp per luminaire, located as the plans show.

(4)For underdeck lighting, provide a separate equipment grounding conductor, equal in size to the

ungrounded conductors, in all runs.

(5)For hand-hole or junction box splices and fuse assemblies, pro vide a neatly trained loop of each

conductor to facilitate removing each splice and each fuse asse mbly from the hand-hole or the junction box for servicing. Ground each hand-hole or junction b ox as the plans show.

(6)Connect the equipment grounding c onductor to the grounding lug in each metal lighting pole. If

transformer bases are required , make the grounding connection t o the transformer base.

(7)Make lighting conductor splices in breakaway bases or hand holes electrically secure using UL or

NRTL approved insulated multi-tap terminal block type connectors. 659.3.3 Luminaires

(1)Provide luminaires together with the hardware and fittings the plans show.

(2)Install utility luminaires on lumi naire arms with an initial r ake of plus 3 degrees, this measurement

includes the rake of the arm. Install luminaires on luminaire a rms level in the longitudinal direction of the highway. Except on segments where the profile is sloped gre ater than 3 degrees, then the engineer will determine the longitudinal level of the luminaires. 659.3.4 Underdeck and Walkway Lighting

(1)Under the Underdeck Lighting bi d item, provide lighting systems under highway bridges together with

the hardware and fittings as plans show.

(2)Under the Lighting Units Walkway bid item, provide standards a nd post-top luminaires, together with

the hardware and fittings the plans show.

(3)Make wires continuous withouts plices from the fuses to the fi rst luminaire and from luminaire to

luminaire.

(4)For underdeck lighting, use one-inch reinforced thermosetting resin conduit conforming to 652. For

condulets and covers, conform to the requirements for loop dete ctor conduit in 652.2.4 .

(5)Install junction boxes for u nderdeck lighting as the plans sho w and as specified in 653. For underdeck

luminaire mounting boxes, if necessary to mount the luminaire, use boxes made of highly corrosion resistant metal and listed for outdoor use. 659.3.5 Lighting Control Cabinet

(1)Provide lighting control cabinets together with the circuit wi ring connections, hardware, and fittings the

plans show.
