mc cable

[electric291]

are anti shorts required for mc cable?

 

[iwire]

No, at least not by the NEC or the manufacturers

I agree...but generally used as "good practice".

I think on the instructions on the MCap it says that no red heads are required but I'm not sure about regular MC.

This is a great link that I have printed and carry folded in 330.

Compare these articles.

330.40 Boxes and Fittings.
Fittings used for connecting Type MC cable to boxes, cabinets, or other equipment shall be listed and identified for such use.

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 300.15.
