Question:
Good morning, Charlie, we are wiring a new big box store and many of the product displays are spec’d to be wired with SO Cord via cord drop from a ceiling mounted box. Does the
NEC® permit SO Cord to be used for hard wiring product display equipment? Thanks, Tom Caldwell

Answer:
Hello Tom, the quick answer is maybe. The use of flexible cord is one of those areas of the Code that can be subjective at times. Wiring of the display cases as described in your question are not necessarily prohibited by any of the “Uses Not Permitted” in Section 400.12(A)(1)-(7). Depending on the specifics of the installation, the display cases may be permitted to be wired with flexible cord in accordance with Section 400.10(6) which applies to the connection of utilization equipment to facilitate frequent interchange. Keep in mind the AHJ will need to agree with this application so it may be beneficial to check with the AHJ beforehand.
