Interior bonding/grounding conductors must be kept a minimum distance from other cables and connectors, except at which location?

• A. Entry or exit of the cabinet
• B. At the splice joints
• C. Near the power supply
• D. In a separate conduit

Answer: (A)

Bonding/grounding conductors are kept away from other cables to reduce interference and ensure a clean, low-impedance grounding path. The one exception is where cables enter or exit the cabinet. At that boundary, the bonding conductor must connect directly to the cabinet’s enclosure to establish a solid equipment grounding path into and out of the cabinet. Requiring distance at the entry/exit point would disrupt the essential ground connection the cabinet needs, so this is the point where the separation rule may be relaxed. In other locations such as splice joints, near the power supply, or when run in a separate conduit, the minimum-distance requirement applies to minimize coupling and signaling issues.
