For an industrial installation, conduit containing only 120V control conductors is routed between enclosures and from enclosures to field devices.
Is there a requirement that 120V control conductors have an EGC routed with them? I know that metallic conduit can serve as the EGC, but is there a requirement that an EGC is required. If the control conduit was PVC would an EGC be required to be routed with the control conductors? Just looking for the NEC code cite.
