Mineral-insulated, metal-sheathed cable shall be supported and secured at intervals not exceeding what distance?

Mineral-insulated, metal-sheathed cable is specifically designed to provide a high level of protection against fire, moisture, and mechanical damage due to its robust construction. The National Electrical Code (NEC) outlines guidelines to ensure these cables are installed securely and safely.

The requirement for supporting and securing these cables at intervals not exceeding 6 feet is crucial for maintaining the integrity of the installation. This ensures that the cable does not sag or become damaged, which can lead to insulation breakdown or exposure of conductors, creating safety hazards.

Additionally, by adhering to the 6-foot interval guideline, installers help to ensure that the cable remains properly placed within walls and ceilings, preventing potential issues from movement or strain on the cable. This standard aligns with best practices for electrical installations, promoting safety and reliability in electrical systems.
