In Class II, Division 1 locations, what is required for interlocked armor Type MC cable?

In Class II, Division 1 locations, interlocked armor Type MC cable must be provided with termination fittings and LFMC (Liquidtight Flexible Metal Conduit) that are listed for the specific application. This requirement ensures that the connections are secure and can withstand the environmental conditions typically present in Class II, Division 1 locations, which are characterized by the presence of combustible dust that could ignite under certain conditions.

Termination fittings serve to create a strong and reliable point of connection to the power source and the equipment, thus minimizing potential exposure to dust and ensuring that the electrical installation is safe. Similarly, using listed fittings and components means they have been tested and approved for use in those hazardous locations, providing extra assurance against potential hazards.

Additionally, the use of LFMC in conjunction with other fittings further ensures the integrity of the installation in terms of both mechanical protection and environmental sealing. This is critical in hazardous areas where dust ignitability is a concern, thereby enhancing safety in electrical installations.
