Don — in your 8/10 posting about need for independent {other-than-raceway} support in the case of using reducing bushings, wouldn’t drilling bolt holes in most {all?} cases constitute modification of the conduit body? I am not aware of conduit bodies furnished with lugs or other mounting means.
Can you or another suggest possible resolution to this? [I understand and do not object to the requirement for additional support.] Thank you for your time. —bjarn
