What kind of armor does the Type MC cable need to possibly change the bend radius standard?

The Type MC cable, or Metal Clad cable, is designed for use in various applications where protection from environmental conditions is necessary. When discussing the bend radius standard for cables, the type of armor surrounding the cable plays a crucial role in determining how flexible and manageable the cable can be without damaging the conductors inside.

Interlocking type armor is specifically designed to allow flexibility while maintaining a protective layer around the conductors. This type of armor is formed by interlocking metal strips, which provide a degree of mobility and allow for tighter bends than some other types of armor. This flexibility can lead to modifications in the bend radius standards, permitting tighter installation configurations when needed.

In contrast, other types of armor such as lead armor, steel armor, or plastic armor do not provide the same level of flexibility. Lead armor is rigid and heavy, making it less accommodating for sharp bends, while steel armor, although strong, also tends to decrease flexibility. Plastic armor, while lightweight and resistant to corrosion, does not offer the same protective qualities or bend radius versatility as interlocking armor.

Therefore, interlocking type armor is pivotal in potentially allowing for a change in the bend radius standard because it maintains a balance between protection and flexibility, catering to installation needs more effectively.
