What must metal raceways be bonded to?

Metal raceways must be effectively bonded to a grounding system to ensure safety and prevent electrical shock hazards. While the specific choices provided suggest various bonding points, the focus should be on the most relevant factors for safe installation.

Metal poles can serve as an effective grounding means if they are properly installed and connected within the grounding system. Bonding raceways to a metal pole may facilitate the establishment of a low-resistance path for fault currents, enhancing safety by reducing the risk of electrocution and fire hazards.

It is critical that any bonding connections are secure and comply with NEC requirements, ensuring that all metal components of the raceway system are connected in a way that provides an effective ground path. This helps maintain electrical continuity, reduces the potential for voltage buildup, and decreases the likelihood of equipment damage during fault conditions.

In the context of electrical installations, it is essential to assess all components and their connections to ensure compliance with the National Electrical Code and proper safety measures.
