When specifying EMT for ICT cables, our default is to specify compression fittings rather than set-screw to ensure the conduit run is electrically continuous. I've reviewed TIA-607-C and cannot find an entry which states this. Is this identified in the NEC, in TIA-607, TDMM, or is this simply "Best Practice" rule of thumb?
Thanks in advance for the assistance

My 2-cents: Both compression and set-screw fittings provide a mechanical bond IF they are tightened properly. A loose compression fitting is just as bad as a loose set-screw fitting. my understanding is that the preference is that the compression fitting does not distort the geometry of the EMT the way a set-screw fitting will. As long as the fill ratio is maintained, the minor distortion made by the set-screw fitting should not affect the usability of the EMT. An additional consideration in favor of using the compression fitting is that if a pull string in not placed in the EMT (or has been pulled out) the compression fittings make it easier to blow a line through the EMT (less air leakage).
