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

Explanation:
Type MC metal-clad cable must be secured every 6 feet during installation according to the National Electrical Code (NEC) standards. This requirement is in place to ensure that the cable is properly supported and protected from physical damage, which could lead to potential hazards. Securing the cable at this interval helps maintain the integrity of the installation and prevents sagging or movement that could occur over time. While other options suggest different intervals, the NEC specifies that 6 feet is necessary to provide adequate support, ensuring safety and compliance with electrical installation standards.
