Nonmetallic Sheathed (NM) Cable — Electrical Wiring

Nonmetallic sheathed cable (NM) is a widely used electrical cable for branch-circuit wiring in residential and light commercial buildings. It consists of insulated conductors bundled within a durable nonmetallic outer jacket, making it straightforward to run for lights, outlets and switches in interior, dry locations. Verify local electrical codes for approved applications and installation requirements.
