Electrical equipment is required to be adequately protected against short-circuit conditions per NEC and OSHA.

Electrical equipment is required to be adequately protected against short-circuit conditions per NEC and OSHA.

• A. True
• B. False
• C. Only NEC
• D. Only OSHA

Answer: (A)

Protecting electrical equipment from short-circuit conditions is required by both NEC and OSHA. The NEC lays out overcurrent protection rules—how fuses and circuit breakers must interrupt fault currents, how conductors and equipment must be rated, and how protection must be coordinated with the system. OSHA enforces workplace safety and relies on the NEC as the baseline for safe electrical installations, ensuring that systems used in workplaces are adequately protected against short circuits. Because both sets of requirements are involved, the statement is true. The idea that only one of the codes applies isn’t accurate in practice, since OSHA enforces safety in workplaces by referencing NEC standards for electrical protection.
