What type of receptacles must be isolated from ground in patient care vicinities?

Isolated grounding-type receptacles are specifically designed to provide enhanced safety in patient care vicinities. These receptacles are intended to minimize the risk of electrical shock and ensure that any stray currents are not directed to the patient, making them crucial in settings where patient safety is the utmost priority.

By being isolated from the ground, these receptacles help in creating a controlled electrical environment, allowing medical equipment to operate without interference from ground loops or unwanted electrical noise. This isolation can significantly decrease the chances of electrical faults causing harm to patients or interfering with sensitive medical devices.

In comparison, ground-fault circuit interrupters offer protection against ground faults but do not inherently provide the same level of electrical isolation. Standard hospital grade receptacles are designed for general use and do not offer the specialized isolation required in patient care areas. The option indicating that none must be bonded is incorrect because patient safety regulations necessitate that certain receptacles be used to ensure proper grounding and isolation in medical environments. Thus, isolated grounding-type receptacles are essential for patient care vicinities.
