Final answer:
The NEC requires that metallic parts of cables be properly grounded at termination points using a grounding conductor to provide a safe path for electrical faults, which helps prevent fires and shocks.
Step-by-step explanation:
If the cable has metallic members, the National Electrical Code (NEC) requires that at termination points, the metallic parts be properly grounded. This is to ensure that there is a path to ground for electrical faults, which can help in preventing fires and electrical shocks. To accomplish this, a grounding conductor is used to connect the metallic components of the cable to the grounding system of the building. This grounding conductor should be continuous and securely attached to grounding terminals or bars. Furthermore, the NEC outlines specific methods and materials for the bonding and grounding of metallic members at termination points, such as the use of listed pressure connectors, soldering, or other approved means to ensure a secure and effective grounding path.
