Cables containing metallic conductors must be properly grounded and bonded.

• A. False
• B. Sometimes
• C. True
• D. Not required

Answer: (C)

Metallic components in cables create a path for fault current, so they must be kept at a safe, predictable electrical potential. Grounding provides a direct, low-impedance path to earth, so any fault current is directed away quickly and protective devices can trip, reducing the risk of shock or fire. Bonding ties all exposed metal parts together so there’s no dangerous voltage difference between them when a fault happens. Together, grounding and bonding ensure safety, reduce stray currents, and meet safety codes for cables that include metal conductors. Therefore, cables containing metallic conductors must be properly grounded and bonded.
