What is Romex?
Romex is a brand name often used generically to refer to non-metallic sheathed cable (NM cable). It consists of multiple conductors enclosed in a plastic jacket and is widely used in residential electrical systems. The cable typically contains a hot wire, neutral wire, and a ground wire, making it ideal for general-purpose wiring.
Romex is favored for its ease of installation, flexibility, and affordability. It is used to connect outlets, switches, and light fixtures in homes. However, it is not rated for outdoor or wet locations and should not be run in exposed areas where it can be physically damaged. Electricians must ensure it complies with local codes, especially regarding its use in commercial properties or conduit systems.
