1.09 GENERAL REQUIREMENTS

1. The America Cable System (TATEFLEX) modular power system is based on zone wiring architecture.  Power system cable management is achieved through the use of multi-conductor cables, run from the power panel to pre-wired master distribution boxes. This method  eliminates individual home run cabling.  The master distribution boxes branch out to feed zone distribution boxes in a hierarchy. From zone locations, factory-sized prefabricated multi-conductor extender cables send power to any point under the floor surface, servicing end users via access floor workstation modules.

   The TATEFLEX modular  power system shall be in accordance with N.E.C. ARTICLE 604 and all applicable U.L. standards.  All components shall be labeled with voltage ratings and installation information.  The system shall be designed and keyed to prevent backfeeding.  All devices and wiring shall be rated for 20 amperes and 600 volt insulation. The connector grounding pin on each modular assembly shall be so designed that the grounding connection is made prior to the contact made within the current carrying conductors per NEC
   410-58d.

2. The TATEFLEX modular horizontal telecommunication cabling system is based on a zone wiring architecture.  Four pair, 100 Ohm UTP or 62/125 optical fiber pairs are bundled in an armored jacket and home run routed from the main or intermediate cross-connect to a zone distribution box. The zone distribution box can be common with that described in 1.09A.  From zone locations, factory-sized prefabricated extender cables transmit voice or data to any point in the work area, servicing end users via industry standard workstation modules.
   
   
   1. The telecommunication system shall provide Category 5 UTP, single mode fiber optic cable, multi-mode fiber optic cable, or any combination of the above.  All cables shall meet the link performance requirements of  EIA/TIA-568a (SP2840).
      
      Note: Category 3 wire is available if specified by the customer, but will not meet the Category 5 link performance criteria.
