| Dedicated AC line - Contractor wants to use BX instead of romex As a result the most likely best path forward is to use the hi purity copper in conduit. It’s just 10-2 with ground NM (Romex) cable that has been sent out and cryoed. (Not by the manufacturer). I wonder what the electrical inspector would say a... | |
