What is the minimum size bonding conductor for the high-voltage secondary circuit of neon signs?

The minimum size bonding conductor for the high-voltage secondary circuit of neon signs is determined by safety standards and electrical codes that aim to ensure proper grounding and bonding in electrical installations. In this context, a 14 AWG copper conductor is appropriate as it provides a balance between conductivity, resistance to damage, and mechanical strength, making it suitable for preventing electrical shock hazards and ensuring efficient operation of the neon sign systems.

Using a bonding conductor that is too small may compromise the ability to effectively carry fault currents, which could lead to overheating or voltage drop issues. 14 AWG is widely accepted as the minimum size because it can safely carry the required currents in typical applications involving neon signage, providing adequate protection while also meeting regulatory requirements.

This standard ensures that safety is prioritized in environments where electrical equipment like neon signs is used, accommodating the necessary currents without risk while facilitating proper bonding to enhance system integrity.
