Product Overview THW 2/0 AWG copper wire is a heavy-duty single-conductor electrical cable designed for power distribution in large residential, commercial, and industrial systems. Constructed with 19 strands of annealed copper and insulated with thermoplastic PVC, it is rated for 600 volts and suitable for both wet and dry locations with a maximum operating temperature of 75°C. This 2/0 gauge copper cable is known for its excellent conductivity, flexibility, and resistance to moisture and abrasion.
Applications of THW 2/0 AWG Copper Wire
- Service entrance and feeder cable in buildings
- Subpanel wiring and HVAC power circuits
- Raceway, conduit, and duct installations
- High-capacity lighting and motor systems
- Underground conduit runs in residential or commercial setups
Thanks to its high ampacity rating and rugged construction, THW 2/0 AWG is ideal for demanding applications that require consistent and safe power delivery.
