2023 NEC handbook, 450.3, blue informational note states: The requirements for OCP for transformer secondaries apply only to the protection of transformers, not the conductors.
What about primary only OCP? Is that also intended only to protect the transformer, not the conductors? It is not specified in the initial statement, but then in the next paragraph states that the OCP for transformers may not provide satisfactory protection for the primary and secondary conductors. Leading me to believe that primary only OCP is to protect the transformer only as well.
