Are Type MC fittings required to be listed and identified for use with Type MC cable?

Type MC fittings indeed need to be listed and identified for use with Type MC cable. This requirement stems from safety standards that ensure electrical components are appropriate for their intended use. Listed fittings are evaluated by a testing authority to ensure they meet specific performance and safety criteria, which helps to prevent hazards such as electrical fires or equipment failures.

Using fittings that are not listed can lead to significant risks, including poor electrical performance or incompatibility with the cable’s insulation and construction. Therefore, having listed fittings establishes a baseline of reliability and safety in electrical installations, making it essential for compliance with electrical codes and standards.

While there might be circumstances under which certain components may not require listing, in the case of Type MC fittings, they unequivocally must be listed and identified to be used properly with Type MC cable, ensuring adherence to industry standards and enhancing overall system safety.
