Grounding Specifications for Devices
Table 10-9 lists the equipment grounding specifications. All communication devices and auxiliary devices (such as mobile base stations, transmission and switching devices, power supply
For telephone, voice, data, and other communication equipment, provide No. 6 AWG minimum green insulated grounding conductor from main building grounding electrode system to each service location, terminal cabinet, wiring closet, and central equipment location.
The Telecommunications Grounding system shall remain separate and shall connect to the electrical grounding system at the main building ground. Grounding Manholes and Handholes: Provide a driven ground rod through manhole or handhole floor, close to wall, and set rod depth so 4 inches will extend above finished floor.
Our cell site grounding,telecommunications grounding and communication tower grounding methods closely follow the Motorola R56 standards and IEEE Std 142-1991 and IEEE Std 142-2007 recommended Practice for Grounding of Industrial and Commercial Power Systems guidelines for cell site and telecommunications sites.
K. Other Communication Room Ground Systems: Ground metallic conduit, wireways, and other metallic equipment located away from equipment racks or cabinets to cable tray or telecommunications ground busbar, whichever is closer, using insulated 16 mm2 (6 AWG) ground wire bonding jumpers.
No bonding conductor shall leave the TR that it is servicing. Grounding to Steel Building Structure: The Telecommunications grounding system shall NOT be grounded using steel building structure. Comply with requirements in Section 260553 "Identification for Electrical Systems" for instruction signs.
Install telecommunications grounding system so resistance to grounding electrode system measures 5 ohms or less. Measure grounding electrode system resistance using an earth test meter, clamp-on ground tester, or computer-based ground meter as defined in IEEE 81.
