Answer: (A)

The important idea here is maintaining a reliable path to earth for fault current in temporary wiring through regular checks. For temporary installations, the equipment grounding conductor must be tested at three-month intervals to verify that the grounding path remains continuous and capable of safely carrying fault current. This is crucial because temporary setups—cords, reels, and receptacles—are more prone to damage, wear, or changes, which can interrupt grounding and create shock or fire risks. The tests focus on confirming continuity of the equipment grounding conductor from the receptacle’s grounding terminal to the system grounding path and ensuring the path remains low impedance. Doing this every three months helps catch degradation early, before a fault occurs. Longer intervals could allow hidden damage to go unnoticed, increasing risk.
