Which organization provides standards referenced with NEC for grounding and bonding of limited energy systems?

• A. NEMA
• B. IEEE
• C. ANSI
• D. TIA

Answer: (D)

Grounding and bonding for limited-energy systems, such as telecommunications and signaling wiring, are guided by standards published by the Telecommunications Industry Association (TIA). The NEC references TIA standards (often seen as ANSI/TIA-607 and related documents) to specify how telecom grounding and bonding should be done. This ensures a consistent, low-impedance path and compatibility with building grounding systems. While organizations like NEMA, IEEE, and ANSI contribute standards in other areas, the NEC specifically uses TIA as the source for grounding/bonding practices for limited-energy (telecom) systems.
