The biggest difference between the two cable systems is that MC has full size ground wire while AC uses a combination of the jacket and a thin bonding strip or wire to function as the equipment ground. Note: Early AC cable often does not have this bonding wire. Now AC cable cannot be used in exterior or damp locations.Click to see full answer. Furthermore, what is AC cable?Type AC cable is a factory assembly of insulated conductors protected in an overall flexible interlocked metallic armor (sheath). The metallic sheath may be of aluminum or steel material. Armored cable having an aluminum sheath is suitable for use in alternating current circuits only.One may also ask, can you use MC cable in a house? Type MC Cable without an outside nonmetallic jacket can be installed in an “other space used for environmental air” in accordance with Section 300.22(C). These cables can be installed either indoors or outdoors and in exposed and concealed locations. They can be installed in a cable tray or in any raceway. what is main difference between DC cable and AC cable? AC current flows through outer surface due to ‘Skin Effect’. Whereas DC current flows throughout the whole cross section diameter of conductor. So DC cable needs Single Strand but AC cable needs Multistranded Copper or Aluminium Conductor bunch for their efficient flow of current.Where is MC cable allowed?Type MC cable is available with an outer PVC jacket and is permitted to be installed in parking decks, concrete pours and for direct earth burial if it is identified for such use. Type MC Cable that is listed and marked for Direct Burial is also suitable for concrete encasement.
