When installing a bonding conductor, which of the following options is NOT recommended?

Choosing to use a conductor smaller than the specified gauge when installing a bonding conductor is indeed not recommended. The rationale behind this recommendation lies in the essential role that bonding conductors play in electrical systems. They are responsible for ensuring a low-resistance path for the fault current, which is vital for the safe operation of electrical equipment and for protecting against electrical shock.

Using a conductor that is smaller than specified can result in several issues, including increased resistance, potential overheating during fault conditions, and failure to effectively clear faults. This not only compromises safety but could also lead to equipment damage and violate electrical codes.

In contrast, keeping the bonding conductor as short as practicable, protecting it from physical damage, and ensuring both ends are bonded properly are all recommended practices. These practices help maintain the integrity and effectiveness of the bonding system, ensuring safety and compliance with regulatory standards.
