Just to add a bit of confusion: http://www.ecmweb.com/nec/code_qa_052104/
The above suggests that _in general_ MC cable is not suitable for health care facilities, because the armor is not suitable as a ground path...but it goes on to reference a product called 'MC SMART' made by ALFLEX. This product is supposed to be MC cable with the necessary bonding strip.
However when I go to http://www.alflex.com/
I can find no reference to this 'MC SMART' stuff. ALFLEX does show an HFC cable, and they clearly describe it as AC cable.
