Our design calls for a 10" piece of 3/4" LFMC to be installed between an LB and the equipment. The conduit contains six 8 awg THHN/THWN conductors.
I would like to use the LFMC as the grounding conductor since including a 10 awg conductor inside the LFMC will exceed the fill limit of 40%. I believe that I meet all of the requirements of 250.118(7) but I'm not sure about 250.118(7)(e). There is no vibration and no expected movement, the LFMC is used to permit ease of alignment. Am I in compliance?
On another note, if I can use the LFMC as a chase nipple as per chapter 9, note (4), I can use 60% fill. Problem is, does the conduit body constitute a box or similar enclosure?
