Hi, we’ve a 1HP air compressor housed in a dedicated weatherproof outdoor cabinet (2ftx2ftx4ft) that provides air to our pond aeration system. It’s 240V and the cabinet interior has dedicated 240V outlets mounted to the inside of the wall. It was previously wired by just having an underground romex come up directly into the cabinet. No conduit. No wire protection. We just installed 1.5” PVC electrical conduit and new wire from the outdoor panel shutoff on the side of the house (similar to an AC outdoor switch panel), underground for 25ft, and up into the underside of the cabinet. What is the appropriate, NEC-compliant, way to go from this conduit to the outlet mounted on the inside of the cabinet? Do I have to continue with rigid conduit inside the cabinet all the way to the outlet, or can I use a whip inside the cabinet? I don't want to leave it as-is because the romex wire between the conduit and the outlet may eventually get damaged with compressor removal/install (for annual maintenance).
Thank you.
Theodore
