At what maximum interval must exposed runs of type MC cable be supported?

The maximum interval at which exposed runs of type MC (Metal Clad) cable must be supported is 6 feet. This guideline ensures that the cable is adequately secured and prevents sagging or damage that could occur if the cable is not properly supported. Supporting the cable at this interval helps maintain the integrity of the installation, reducing the risk of mechanical damage and electrical hazards.

Regulatory codes, such as the National Electrical Code (NEC), dictate these support requirements to promote safety in electrical installations. Each specified support interval serves to ensure that cables are not only safe but also function effectively within their intended applications. Adhering to these regulations is crucial in any electrical work to prevent potential issues and ensure compliance with industry standards.
