Enclosures containing service conductors, including meter fittings and boxes interposed in a raceway or armor shall be effectively bonded to which electrical material?

• A. Non-Current Carrying Metal Parts
• B. Conductor Disconnects
• C. Branch Circuits
• D. Threaded Couplings

Answer: (A)

The correct answer is that enclosures containing service conductors, including meter fittings and boxes interposed in a raceway or armor, should be effectively bonded to non-current carrying metal parts. This is because proper bonding ensures that any fault currents or electrical issues are safely directed to the ground, reducing the risk of electric shock or fire. Non-current carrying metal parts, such as enclosures and conduits, serve as an important safety feature in electrical installations, allowing the grounding system to function correctly and providing a path for any stray currents to dissipate safely. This principle is in line with the National Electrical Code (NEC), which emphasizes the importance of grounding and bonding for the safety of electrical systems. Non-current carrying metal components do not conduct electricity under normal operation, making them ideal candidates for bonding to ensure that they can effectively carry any fault currents safely to ground when needed.
