Which guideline addresses grounding deficiencies in electrical systems?

• A. National Fire Protection Association 1911/1910 Line Voltage Maintenance
• B. National Fire Protection Association 1911/1910 Inspection and Maintenance
• C. National Fire Protection Association 1911/1910 Grounding Deficiencies
• D. National Fire Protection Association 1911/1910 Performance Testing

Answer: (C)

Grounding provides a low-impedance path for fault current, which helps protective devices trip and keeps exposed metal at a safe potential. When grounding is inadequate, faults may not clear properly, increasing shock risk and equipment damage. The guideline that directly addresses this issue is the one specifically titled Grounding Deficiencies. It guides how to identify signs of grounding problems, document them, and take corrective actions to restore a proper grounding system—covering aspects like proper conductor connections, bonding, continuity, and verification after remediation. Other guidelines cover broader topics such as general inspection, maintenance, or performance testing, but they don’t focus on the specific process of identifying and correcting grounding deficiencies.
