In the past, I have seen drawings from certain radiology equipment manufacturers showing the 5 foot lengths of wall duct (that I would install for them and holds their cables), to be bonded at each section. If this does not appear on a specific set of drawings I have, is it required in some code? I could bond at one location and all the other pieces are connected via a manufactured coupling that is tapped and screwed by at least four screws.
