Romex vs MC Cable: What’s the Difference?
As mentioned earlier, both Romex and MC cable are used frequently in residential settings and are permitted by NEC regulations. However, there are distinct differences between the two that should be taken into consideration before deciding on their installation. Romex: Romex is a brand name for a type of electrical wiring that is made up of two or more insulated wires wrapped in a flexible plastic sheath. It is often referred to as non-metallic cable or NM cable. Romex cable is commonly used for residential applications and is suitable for use in walls, floors, and ceilings. MC Cable: MC (Metal-Clad) cable, on the other hand, consists of multiple stranded conductors wrapped in a flexible metal jacket. It is commonly used for commercial and industrial settings, but can also be used in certain residential applications. The key difference between the two types of cables is the way they are constructed. Romex is made up of insulated wires wrapped in a plastic sheath, while MC cable is made up of stranded conductors wrapped in a metal jacket. This difference in construction affects the types of settings in which each cable is best suited for installation.Overview of Romex Cable
