PART 2 - PRODUCTS

2.1PROPRIETARY WIRING SYSTEM COMPONENTS

  1. Manufacturers: As directed by the Owner, provide products to match an existing proprietary wiring system, or to match components included with lighting fixtures furnished under separate contract. Provide products as manufactured by one of the following:
  2. AFC
  3. Dualite
  4. ADI
  5. Holophane
  6. Approved Substitute.
  7. General
  8. Provide system components in accordance with UL 183.
  9. Do not use direct wired connections in the system except for connections to flush, wall-mounted wiring devices such as line voltages switches and receptacle outlets.
  10. Install lighting fixture connector on top of fixture. Coordinate location with lighting fixture manufacturer and Division 23 work to prevent interferences with HVAC ductwork, air supply/return boots, and piping.
  11. Connections to fluorescent lighting fixtures shall not require more than 6 inches of clearance above the top of the fixture.
  12. Provide system which can branch circuit in three directions from one cable set point, T-tap connection, and can couple together two cable sets to form one single, longer cable set.
  13. Provide a system which is UL listed for disconnecting under load.
  14. Cable Sets
  15. Provide each cable set with the number of phase conductors indicated and as required for power and switching functions, one neutral conductor and one equipment ground.
  16. Provide minimum No. 12 AWG, stranded copper conductors with 600 Volts, 90°C insulation.
  17. Provide Type AC or MC cable.
  18. Provide plug-in connectors at both ends of cable sets except for cable sets which connect to wall-mounted wiring devices, in which direct-wired type connections are permitted.
  19. Plug/Receptacle Connectors
  20. Provide physical keying design to prevent mixing of different service and voltage systems; integral to the plug/receptacle connector, which cannot be defeated except by destroying the connector.
  21. Provide dead-front safety design with recessed electrical contacts.
  22. Provide a positive locking mechanism to ensure a mechanical and electrical connection which cannot be undone through normal handling.
  23. Provide connectors at ends of cable sets, lighting fixtures, and other specified equipment which allow for mechanical and electrical connections to be made between equipment without the use of tools for the making and breaking of connections.
  24. Grounding
  25. Provide a separate equipment grounding conductor throughout system components.
  26. Provide copper terminals in plug/receptacle connectors for connection of grounding conductor between components.
  27. Identification: Permanently mark components as to voltage and function utilizing both unique color-coding and textural means.

PART 3 - EXECUTION

3.1INSTALLATION

  1. General
  2. Where applicable, secure cable sets to ceiling tile stringers supported 12 to 18inches above the ceiling grid and with no more than one cable set per stringer.
  3. Do not rest cable sets on ceiling tiles, HVAC ducts, and other equipment.
  4. Plug unused openings.
  5. Do not install cable sets in nonaccessible areas except for cable drops to wall-mounted switches.
  6. Install system as a concealed system in finished areas and exposed in nonfinished and production areas.
  7. Install distribution boxes securely to the building structure.
  8. Install distribution boxes above lay-in ceilings to be easily accessible, requiring only the removal of a ceiling tile, and mount approximately 12 inches above finished ceiling line. Provide necessary structural support to permit the above mounting location and height.
  9. Identification
  10. Provide lettered plastic tape identification, in accordance with Section “Electrical Identification,” at each distribution box receptacle indicating the following lines of information:
  11. Power source (e.g., “Fed from LP1”)
  12. Circuit number (e.g., “Circuit 9”)
