How often must mineral-insulated, metal-sheathed cable be supported and secured?

Mineral-insulated, metal-sheathed cable must be supported and secured at a maximum distance of 6 feet. This requirement helps ensure the integrity and safety of the electrical installation by preventing sagging or mechanical damage to the cable. The specific support and securing distance is crucial for maintaining code compliance and ensuring that the cable can withstand environmental stresses and physical handling.

Regular support and securing at the specified intervals minimizes the risk of electrical faults, wear, and tear on the insulation, which can lead to short circuits or other hazardous conditions. While other distances (such as 3, 4, or 5 feet) may apply to different types of wiring or cables, the 6-foot standard is specifically applicable to mineral-insulated, metal-sheathed cable, reflecting industry best practices aimed at promoting safety and reliability in electrical systems.
