NM cable

NM cable, also known as Non-Metallic Sheathed Cable or Romex, is a type of electrical wiring commonly used in residential construction. It features insulated conductors (wires) bundled together inside a flexible plastic sheath, providing a safe, organized way to distribute electrical power throughout a home. The plastic covering protects the wires from damage and contact with other materials. NM cable is easy to install, code-compliant, and suitable for interior wiring where it’s protected from moisture and physical damage. It’s a standard choice for wiring outlets, switches, and lighting fixtures in residential buildings.
