Is Type MC cable containing an insulated EGC permitted to be used within patient care areas?

Type MC (Metal Clad) cable contains insulated conductors and includes an Equipment Grounding Conductor (EGC). However, the use of this type of cable within patient care areas is restricted due to safety and regulatory standards set forth by the National Electric Code (NEC) and other relevant guidelines ensuring the safety of electrical systems in healthcare facilities.

In patient care areas, which include locations where healthcare services are provided or where patients are treated, there are strict requirements for medical electrical equipment and wiring methods. These areas require the use of specific types of wiring to minimize the risk of electrical shock, equipment failure, and interference with the operation of medical devices. The NEC specifies that only certain types of cable, such as Type AC (Armored Cable) or other specially designed cables, should be used in these settings to ensure the highest levels of safety.

The rationale behind the restriction is rooted in the unique and sensitive nature of medical environments, where any failure in the electrical system could directly impact patient safety. Therefore, using Type MC cable with insulated EGC within patient care areas is not permitted to adhere to these safety requirements.
