We have rigid metal conduit that transitions from underground duct banks and is routed to these electrical junction boxes as shown in the image below. The conduit is not supported within 3 feet of the junction box as required by NEC 344.30 and it has been identified as a deficiency by the engineer. What are the Code rules for allowable support means of boxes and conduit bodies? A. Boxes can be fastened to any surface that provides adequate support [Sec. 314.23(A)].
