III . LIGHTING SYSTEM CONSTRUCTION <br /> A. SYSTEM DESCRIPTION <br /> Lighting system shall consist of the following : <br /> 1 . Galvanized steel poles and crossarm assembly (LSG Only) <br /> 2. Pre-stressed concrete base embedded in concrete backfill (LSG Only) <br /> 3 . All luminaires shall be constructed with a die-cast aluminum housing to protect the luminaire <br /> reflector system . <br /> 4. Luminaire, visor, and crossarm shall withstand 150 mph winds and maintain luminaire aiming <br /> alignment. <br /> 5. Manufacturer will remote all ballasts and supporting electrical equipment in aluminum <br /> enclosures mounted approximately 10' above grade. The enclosures shall include ballast, <br /> capacitor and fusing for each luminaire. Safety disconnect per circuit for each pole structure <br /> will be located in the enclosure. <br /> 6. Wire harness complete with an abrasion protection sleeve, strain relief and plug-in connections <br /> for fast, trouble free installation . <br /> 7. Controls and Monitoring Cabinet to provide on-off control and monitoring of the lighting system, <br /> constructed of NEMA Type 4 aluminum . Communication method shall be provided by <br /> manufacturer. Cabinet shall contain custom configured contactor modules for 30 , 60, and 100 <br /> amps, labeled to match Feld diagrams and electrical design . Manual Off-On-Auto selector <br /> switches shall be provided . (Standard LSG/Optional SCG) <br /> B. MANUFACTURING REQUIREMENTS <br /> All components shall be designed and manufactured as a system . All luminaires , wire harnesses , <br /> ballast and other enclosures shall be factory assembled, aimed , wired and tested . <br /> C. DURABILITY <br /> All exposed components shall be constructed of corrosion resistant material and/or coated to help <br /> prevent corrosion . All exposed steel shall be hot dip galvanized per ASTM Al 23. All exposed <br /> hardware and fasteners shall be stainless steel of at least 18-8 grade, passivated and polymer <br /> coated to prevent possible galvanic corrosion to adjoining metals. All exposed aluminum shall be <br /> powder coated with high performance polyester. All exterior reflective inserts shall be anodized , <br /> coated with a clear, high gloss , durable fluorocarbon , and protected from direct environmental <br /> exposure to prevent reflective degradation or corrosion . All wiring shall be enclosed within the <br /> crossarms, pole, or electrical components enclosure. <br /> D. LIGHTNING PROTECTION <br /> Ail structures shall be equipped with lightning protection meeting NFPA 780 standards . Contractor <br /> shall supply and install a ground rod of not less than 5/8" in diameter and 8' in length , with a <br /> minimum of 10' embedment. Ground rod should be connected to the structure by a copper main <br /> down conductor with a minimum size of #2 for poles with less than 75' mounting height and 2/0 for <br /> poles with more than 75' mounting height. <br /> E. SAFETY <br /> All system components shall be UL Listed for the appropriate application . <br /> F. ELECTRIC POWER REQUIREMENTS FOR SPORTS LIGHTING EQUIPMENT <br /> Maximum total voltage drop to the disconnect switch located on the poles shall not exceed 3 <br /> percent of rated voltage. <br /> 1 . Voltage/Phase to be determined for each specific site . <br /> IV. DELIVERY TIMING <br /> The equipment must be on site 4-6 weeks from the receipt of approved submittals and receipt of <br /> complete order information . <br /> Jacksonville Spec 04-24r5.doc 8 Created on 12/1 /2006 4:32 PM <br />
