NFPA __________ requires all outlets be equipped with ground fault circuit interrupters.

NFPA __________ requires all outlets be equipped with ground fault circuit interrupters.

• A. NFPA 70E
• B. NFPA 70
• C. NFPA 72
• D. NFPA 1

Answer: (A)

Ground fault circuit interrupter protection is a requirement tied to electrical installations, and that guidance comes from NFPA 70, the National Electrical Code. GFCIs are designed to detect even small imbalances between the hot and neutral currents and trip the circuit in about a fraction of a second, preventing shock in areas where moisture or other conditions raise the risk of electrical contact. The NEC specifies which locations require GFCI-protected outlets, particularly wet or damp areas and outdoor receptacles, helping to keep people safe during everyday use. NFPA 70E, by contrast, focuses on safe work practices and electricity safety in the workplace rather than installation rules. NFPA 72 covers fire alarm and signaling systems, and NFPA 1 is the Fire Code addressing broader fire safety requirements. So, the outlet GFCI requirement is grounded in NFPA 70.
