In health care facilities, the grounding terminals of isolated ground receptacles installed in patient care spaces shall be connected to what?

The grounding terminals of isolated ground receptacles installed in patient care spaces are required to be connected to an insulated equipment grounding conductor because this approach enhances electrical safety and reliability in environments where patients are present. An insulated equipment grounding conductor provides a dedicated path for fault currents, reducing the risk of electric shock and ensuring that ground faults are promptly cleared by protective devices.

In patient care environments, the need for a reliable grounding system is critical, as it helps maintain the integrity of sensitive medical equipment and protects patients from potential electrical hazards. An insulated equipment grounding conductor also minimizes the chance of stray currents, which can interfere with sensitive devices and impact patient safety.

This choice aligns with electrical safety codes and standards that emphasize the importance of proper grounding practices in healthcare settings to protect both patients and medical equipment.
