Question

Electrical equipment is required to be adequately protected against short-circuit current conditions per NEC 110.10 and several other complementary NEC requirements. OSHA requires equipment short-circuit current protection in 1910.303(B)(viii)(5).

Answer 1

ANSWER:

The statment is true.

STEP-BY-STEP EXPLANATION:

Per Osha 1910.303 b (5):

The overcurrent protective devices, the total impedance, the component short-circuit current ratings, and other characteristics of the circuit to be protected shall be selected and coordinated to permit the circuit protective devices used to clear a fault to do so without the occurrence of extensive damage to the electrical components of the circuit. This fault shall be assumed to be either between two or more of the circuit conductors, or between any circuit conductor and the grounding conductor or enclosing metal raceway.
