In patient care areas, grounding terminals of receptacles are required for equipment operating at what voltage?

1. 120V

2. 240V

3. 480V

4. Over 600V

The correct answer is: Over 600V

Grounding terminals of receptacles in patient care areas are critical for ensuring safety and minimizing the risk of electrical shock to patients, especially those who may have compromised health. In healthcare settings, equipment that operates at higher voltages can present significant hazards. The requirement for grounding terminals for equipment operating at voltages over 600V stems from the understanding that electrical systems at these levels can cause more severe injuries or fatalities. Equipment used in patient care areas must be rigorously designed to protect against electrical faults, and grounding systems play a vital role in this protection by directing excess voltage away from patients and personnel. This is particularly important because the risk of shock must be mitigated given the vulnerable nature of patients in such environments. Equipment operating at lower voltages, like 120V or even 240V, typically does not carry the same level of risk, and the safety measures for these voltages are generally less stringent. Therefore, ensuring robust grounding for equipment operating over 600V aligns with safety standards and practices in healthcare facilities, prioritizing patient and staff safety.
