You are designing a telecommunications grounding system for a telecommunications room (TR). The TMGB is located 15 m (50 ft) from the telecommunications rack. What is the MINIMUM AWG of the ground conductor required?
You are designing a telecommunications grounding system for a telecommunications room (TR). The TMGB is located 15 m (50 ft) from the telecommunications rack. What is the MINIMUM AWG of the ground conductor required?
For telecommunications grounding systems, the minimum American Wire Gauge (AWG) for a ground conductor over distances up to approximately 30 meters (100 feet) is 6 AWG. Since the distance between the TMGB and the telecommunications rack is 15 meters (50 feet), a 6 AWG ground conductor is required.
TDMM page 8-22 (788) In most applications, where any bonding conductor does not exceed ~30m (100 ft), a minimum of a 6 AWG bonding conductor is sufficient.
