Romex (NM cable)
Romex, or NM (non-metallic) cable, is a type of electrical wiring commonly used in residential buildings. It consists of multiple insulated wires encased in a plastic sheath, allowing safe and efficient transmission of electricity. Romex is typically used for indoor wiring, connecting outlets, switches, and lighting fixtures. It’s preferred for its ease of installation and flexibility. The standard colors indicate the wire gauge and, consequently, the amount of current it can safely carry. Overall, Romex is essential for ensuring electrical systems operate safely and effectively in homes.
