I need to refeed an existing pool light transformer. I noticed the subpanel is feed with 10/3 or 12/3 romex it feeds 230v pool pump and light. This was installed 20 years ago or more. Is Romex feeding a pool subpanel legal. According to 680.25 A Exception. An existing feeder between remote panelboard and service equipment shall be permitted to be run in an approved cable assembly that includes an equipment grounding conductor within its outer sheath is. So I wounld think a bare grounding conductor is ok and does not need to be insulated. Am I right
