What requirement is there for bonding methods in hazardous locations regarding metal raceways?

The requirement for bonding methods in hazardous locations, particularly in the context of metal raceways, emphasizes the importance of electrical safety and the prevention of hazardous conditions. The correct choice highlights that bonding must extend to all intervening metal raceways. This practice ensures that all conductive parts of the electrical system are at the same electrical potential, which minimizes the risk of electrical shock and prevents the potential for arcing or other electrical hazards.

In hazardous locations, such as those where flammable gases or vapors are present, it is crucial that all metallic components within the system are effectively bonded together. This is because if different parts of the raceway system are at different potentials, it could lead to dangerous situations. Proper bonding across all intervening metal raceways allows for the safe dissipation of fault currents and provides a reliable path back to the ground, thus safeguarding both equipment and personnel.

The other options suggest practices that do not align with these safety principles. For instance, not connecting to a grounding point would risk creating a potential difference. Similarly, indicating bonding is not applicable in classified locations contradicts the very essence of safety in hazardous environments, where precautions must be paramount. Lastly, limiting installation solely at the equipment does not account for the necessary continuity required throughout
