Navigation lights must operate from sunset to sunrise and during periods oflow visibility.  \n510-2 Coordination of Electrical Work.  \nUse experienced personnel in the type of work required by the Contract Documents to provide a complete and satisfactory fitting and fully operational installation. Perform all electrical work either by, or under the immediate supervision of an electrical journeyman.  \nSchedule and arrange electrical work in a neat, well-organized manner without interference with the work scheduling of other trades.  \n510-3 Materials and Equipment.  \nMeet the equipment and material requirements as shown in the Contract Documents.  \nFurnish and install only materials and equipment of new stock meeting ANSI, NEC, NEMA, and UL requirements, and approved by the Engineer, except where the Contract Documents allow or specify the use of other than new equipment.  \nFurnish and install marine type products manufactured of corrosion resistant materials.  \nFurnish and install only fasteners manufactured from ASTM 316 stainless steel with yield strength 35,000 psi or higher.  \nFurnish and install ASTM 300 series stainless steel conduit straps or hangers held at not less than two points.  \nFurnish and install framework for supporting boxes, switches, and other externally mounted electrical devices fabricated from ASTM A709 Grade 36 hot-dip galvanized structural steel.  \n510-4 Navigation Lights and Aids.  \n510-4.1 Navigation Lights: Equip all navigation lights with a LED array with a minimum of 50,000 hour life and bright enough to meet the visibility requirements ofCFR Title 33, Part 118. Mount LED arrays on an internal shock and vibration isolator. Provide, in the circuit, a lightning surge suppressor capable of absorbing multiple strikes without replacement. Provide special power supply to provide current limited DC voltage to the LED array.  \nFurnish and install fixtures with unpainted housings of heavy duty cast aluminum or bronze construction with a 1-1/2 to 2 inch threaded conduit opening on the bottom. Use only marine type mounting boxes with minimum 3/4 inch conduit opening. Furnish and install fixtures with lenses that are standard marine molded, single-piece fresnel type, rigid, heat resistant glass or U.V. resistant polycarbonate and inside diameter of 7 to 8 inch. Furnish all stainless steel closure bolts, lens tie rods, and attachment hardware for a complete and accepted installation.  \nFurnish and install pier/fender lights, center channel lights and channel margin lights with cast aluminum or bronze swivel assembly and mounting bracket, complete with stainless steel pivot, watertight “O” ring seal, bronze bearings, cable entrance fitting, and stainless steel service chain rated for a minimum 225 pounds load. Use a 1-1/2 or 2 inch galvanized pipe or stainless steel pipe as a hanger stem with automatic lock at service and operating positions. Furnish and install a 60% counterweight if stem exceeds 5 feet in length.  \nEnsure the pier/fender Light is equipped with a red 180 degree lens, the center channel light is equipped with a green 360 degree lens and the channel margin light is equipped with a red 180 degree lens.  \n510-4.2 Clearance Gauge Lights: Furnish and install one-piece die-cast aluminum fixture housing fitted with watertight gasket, stainless steel hinges and fasteners, and adjustable aiming capability, equipped with a 120 VAC 50 watt, high-pressure sodium lamp. Use a heavy cast aluminum connection box body and cover with stainless steel swing bolts, water","cbCainKNjsS0kZrg","https://ap.wps.com/l/cbCainKNjsS0kZrg","pdf",16260,"English","# SECTION 510\n## 510-1 Description\n## 510-2 Coordination of Electrical Work\n## 510-3 Materials and Equipment\n## 510-4 Navigation Lights and Aids\n## 510-5 Disconnect Switches\n## 510-6 Supporting and Mounting Devices","[{\"question\":\"What are the required operating conditions for bridge navigation lights?\",\"answer\":\"Navigation lights must operate from sunset to sunrise and during periods of low visibility.\"},{\"question\":\"What minimum LED life and surge protection are required for navigation light assemblies?\",\"answer\":\"Each navigation light must use a LED array with a minimum of 50,000 hour life and include a circuit lightning surge suppressor capable of absorbing multiple strikes without replacement.\"},{\"question\":\"What are the key requirements for disconnect switches and enclosures?\",\"answer\":\"Disconnect switches must be HP rated, meet Federal and NEMA specifications, use NEMA Type 4X (stainless steel) enclosures, include front cover mounted nameplates with permanent records, and provide mechanisms with positive quick make-quick break operation.\"}]","SECTION 510 - Navigation Lights for Fixed Bridges | PDF",1790167706,13]
