One advantage of using metal-clad (M/C) cable in installations is its protection against physical damage. M/C cable features a robust metal sheath that allows it to withstand impacts, abrasions, and other forms of mechanical stress that can occur in various environments. This makes it particularly suitable for applications where cables may be exposed to rough handling, external forces, or potentially hazardous conditions. The enhanced durability and resilience of M/C cable contribute significantly to maintaining electrical system integrity and safety, reducing the risks associated with cable damage and potential electrical hazards.

While lower material costs, better insulating properties, and ease of installation have their own benefits in certain contexts, they do not provide the same level of protection that M/C cable offers against physical damage. This is a primary reason why M/C cable is often selected for specific industrial and commercial applications where safety and longevity of the installation are paramount.
