We are running 24VAC HVAC control cables at a university for push button and horn. Where the cables enter the wall we installed a flex whip to a cut-in handy box (metal tiger-grip). Does the flex require a flex connector at the end where the cable exits the drywall? I say no because a flex connector isn't listed as a bushing. My coworker thinks otherwise but can't find it in the NEC. We have fire caulked both the flex opening and wall penetration.
