Which NEC table provides grounding conductor size for communication systems covered in Article 800?

The correct response is that no specific table is required for determining the grounding conductor size for communication systems as outlined in Article 800. This is rooted in the understanding that while the National Electrical Code (NEC) provides guidelines and requirements for the grounding and bonding of various systems, communication systems following Article 800 have separate considerations.

The grounding requirements for communication systems are inherently different due to their unique operational setups and environmental factors. Article 800 discusses the installation of communication circuits, including telephone and data systems. Instead of relying on a dedicated table, these systems generally follow specific provisions in Article 800 and may also refer to general grounding methods without the necessity for a specific sizing table.

While tables such as 250.66, 250.122, and 800.80 do exist, they pertain to different applications or general grounding/bonding requirements for other electrical systems. Understanding that communication systems have distinct grounding practices is key to recognizing why no table is necessary for sizing grounding conductors under Article 800.
