ICC Residential Electrical Inspectors Practice Exam 2025 – Complete Prep Guide

The correct choice, ensuring continuity for raceways, highlights the importance of maintaining a continuous electrical path in metal raceways. Bonding lock nuts are specifically designed to effectively connect and bond the metal raceway to the equipment or junction box. This ensures that any potential fault current has a safe and efficient path to ground, which is vital for the safety of the electrical system.

Metal raceways must be properly bonded to prevent electrical shock hazards and to ensure the system behaves as intended under fault conditions. The use of listed bonding type lock nuts provides a secure connection that meets code requirements, thus promoting safety and compliance in electrical installations.

While bonding metallic piping systems, connecting ground wires, and mounting electrical boxes are important aspects of electrical work, they do not specifically involve the specialized use of a bonding type lock nut in the same way that ensuring continuity for raceways does.
