i would like to see some photos of this one to be sure i know what you mean because there are a few different types and it seems like we are wasting time doing both the insulated connector and the antishort
i think we used the ones sparky is talking about and also had to use the antishorts... no big deal on small jobs but its a big deal on something like a $30 million dollar school

i'm curious what you saw Joe and where this is a problem
also wondering if i missed something Sparky cause i reread these and noticed you said MC, which you dont need anti-short bushings with anyway, right?
what i read in 320.40 is only the AC cable [with the 16awg bond wire] needs the bushing or "equivalent" visible and we dont use much AC except hcf in medical buildings, the insulated throats [equivalent?] are visible at cover

Keep in mind too, that some BX connectors are not rated for MC wire. Always make sure that the connector you are using is rated for that wire. Some MC connectors are squeeze tight style while some BX connectors rely on the screw type connectors.

330.40 does not include the wordage that 320.40 has
320.40 Boxes and Fittings. At all points where the armor of AC cable terminates, a fitting shall be provided to protect wires from abrasion, unless the design of the outlet boxes or fittings is such as to afford equivalent protection, and, in addition, an insulating bushing or its equivalent protection shall be provided between the conductors and the armor. The connector or clamp by which the Type AC cable is fastened to boxes or cabinets shall be of such design that the insulating bushing or its equivalent will be visible for inspection. Where change is made from Type AC cable to other cable or raceway wiring methods, a box, fitting, or conduit body shall be installed at junction points as required in
330.40 Boxes and Fitting. Fittings used for connecting Type MC cable to boxes, cabinets, or other equipment shall be listed and identified for such use.
Q~am i to assume that insulated throat connectors serve as a connector/red combo in either application???
