I recently had a call-back concerning zip cord. Here’s what my research showed, and when the Realtor asked the local AHJ (at my suggestion) his opinion, the local AHJ backed up my research and complimented me on it. He had never seen such research from a home inspector before.
Supply cord, flexible cord, flexible cable, fixture wires, and extension cord sets are allowed by the NEC but must be of a certain size depending on the amperage of the branch circuit and must be appropriately protected against overcurrent. The NEC also states that the total rating of utilization equipment fastened in place should not exceed 50 percent of the branch circuit ampere rating where other equipment is also supplied. As noted in our home inspection report, none of the circuits were labeled, so we couldn?t determine whether the supply cord, fixture wires, or extension cord sets were appropriate for the installations present. Nor could we determine whether the 50-percent threshold was or was not being exceeded. Such technical calculations are not even within the scope of the home inspection; they are reserved by California law to licensed electricians. That?s why we then recommended, under the same note, ?further evaluation by qualified electrician to help ensure safety.?
Consult with your local AHJ concerning zip cords, etc.
