What is the purpose of the internal bonding strip in Type AC cable?

The internal bonding strip in Type AC cable serves a critical function in ensuring safety and performance by maintaining electrical continuity between the cable's internal components and its outer armor. This contact is essential for effective grounding, which protects against electrical faults and reduces the risk of shock hazards.

By providing a reliable path for fault current to the ground, the internal bonding strip enhances the overall safety of the electrical system. This grounding functionality is especially important in environments where the cable may be subjected to mechanical strain or where exposure to moisture and other environmental factors could pose risks related to electrical safety. Thus, the design of the AC cable incorporates this bonding strip to ensure that even if the outer armor of the cable becomes damaged, there is still a reliable grounding connection that can protect users and equipment.
