NEC 348.30(A)

[gdsodrnk1]

This article addresses the support of FMC. Specifically it states, "FMC shall be securely fastened in place by an approved means within 300mm(12in) of each box, cabinet, conduit body, or other termination...."

Exception 2 allows this distance to be increased if the FMC is installed for flexibility after installation. The distances are increased from "the last point where the FMC is securely fastened".

Is a connector, for a transformer install, considered a "securely fastened" point? For exception 4, a connector is specifically allowed as a means of securement and fastening.
