The design and installation of the electrical system will be regulated by which NFPA standard?

• A. NFPA 70
• B. NFPA 13
• C. NFPA 25
• D. NFPA 101

Answer: (A)

The main concept is that electrical design and installation are governed by the National Electrical Code, NFPA 70. This standard provides the specific requirements for electrical wiring methods, sizing of conductors, overcurrent protection, grounding and bonding, electrical equipment installation, and general electrical safety in buildings. Inspectors use NFPA 70 to verify that electrical work is performed safely and in compliance with the code adopted by the jurisdiction.

NFPA 13 governs the design and installation of automatic sprinkler systems, NFPA 25 covers inspection, testing, and maintenance of sprinkler systems, and NFPA 101 (Life Safety Code) addresses overall life-safety provisions, means of egress, occupancy classifications, and other safety features, rather than the detailed electrical installation rules.
