If the equipment grounding conductor is run inside flexible metal conduit (FMC) and measures 8 feet, is this compliant with code?

Running an equipment grounding conductor inside flexible metal conduit (FMC) can be compliant with code if the installation meets specific requirements. In the National Electrical Code (NEC), the equipment grounding conductor must be properly sized and securely connected. An 8-foot run of equipment grounding conductor within FMC generally meets the length requirement for continuity and protection against physical damage, as there are no strict rules limiting the length of a grounding conductor inside conduit as long as the connections and sizes are appropriate.

Furthermore, FMC is recognized as an acceptable method for grounding in many installations because it provides physical protection and can serve as a grounding path as long as the conduit is effectively bonded. The critical aspect is ensuring that all connections are properly made and that the grounding conductor is of adequate size relative to the circuit it serves.

While other aspects such as the type of equipment or securing of the conduit might affect compliance in certain contexts, the information presented supports the conclusion that in this situation, an 8-foot equipment grounding conductor within FMC is compliant with code.
