I have a local inspector referring me to 312.6(C), and telling me that plastic bushings are required on SE Cable Type connectors entering a load center or meter enclosure. The size cable in the connectors would be either 2/0 or 4/0. Is the inspector correct, or is my interpretation that the article he is referring to is relating to conductors in a raceway and SE Cable in a SE connector would not require a plastic bushing?
