Type MC or Type AC cable?
Posted by super from New York, NY, USA on January 23, 2009
I have a choice of using either Type MC and Type AC cable to feed IG receptacles. Which type is better for this application?
Both types are fine, but Type MC does have some restrictions. New wording in Sec. 250-146(D) in the 2008 NEC clarifies the use of these types of cables. Basically it allows you to use Type AC cable having an insulated equipment grounding conductor because its metallic armor is listed as an equipment grounding conductor. You can also use spiral interlocked Type MC cable having two equipment grounding conductors. You cannot use regular Type MC cable having an insulated grounding conductor because its armor is not listed as an equipment grounding conductor.
