The minimum-size bonding conductor for metal parts associated with neon sign installations shall not be less than?

• A. 10 AWG Copper
• B. 12 AWG Copper
• C. 14 AWG Copper
• D. 16 AWG Copper

Answer: (C)

The minimum-size bonding conductor required for neon sign installations is specified to ensure safety and adequate grounding. A bonding conductor is essential for connecting metal parts to help prevent electrical shock and minimize the risk of fire. In neon sign applications, the regulation specifies that the bonding conductor must be made of copper and not smaller than 14 AWG. This size is deemed adequate to handle the potential fault current that might flow through it, providing sufficient conductivity and mechanical stability. The choice of 14 AWG copper balances the requirements for safety while also ensuring that the conductor is not overly bulky or difficult to work with in installation. Choosing a larger size like 10 AWG or 12 AWG may provide additional safety margins, but they are unnecessary based on code requirements for bonding conductors in this specific application, thus making 14 AWG the correct minimum size. A 16 AWG conductor would be too small, potentially leading to overheating or failure under fault conditions. Therefore, compliance with the 14 AWG minimum size helps ensure both safe and effective bonding in neon sign installations.
