How often must Type MC metal-clad cable be secured?

Type MC metal-clad cable must be secured at intervals not exceeding 6 feet. This requirement is essential to ensure that the cable remains stable and free from damage, especially in environments where mechanical stresses may be present. Securing the cable properly helps to prevent strain on the connections and minimizes the risk of electrical hazards, such as short circuits or cable wear.

The specification for securing wire and cable types, including MC cable, is part of compliance with the National Electrical Code (NEC), which seeks to maintain safety and reliability in electrical installations. By adhering to the 6-foot requirement, electricians can ensure that the cable is adequately supported and protected throughout its installation.
