Is it true that a grounding electrode conductor for a communications system must be sized using NEC Table 250.66?

• A. True
• B. False
• C. Only for new installations
• D. Only if it is over 100 feet

Answer: (B)

The size of a grounding electrode conductor for a communications system is not governed by NEC Table 250.66, which is specifically intended for sizing grounding electrode conductors for service-entrance conductors and feeder conductors. Instead, grounding and bonding requirements for communications systems are usually addressed in Article 800 of the National Electrical Code (NEC). This article provides guidelines that are distinct from those found in Table 250.66, which focuses on electrical systems rather than communications systems. Communications systems often have different requirements for grounding and bonding, reflecting their operational and safety needs. While proper grounding is crucial for the performance and safety of communications equipment, the sizing standard is not derived from the same source as that for general electrical installations, making the statement false.
