Product Overview THW 4 AWG copper wire is a heavy-duty single-conductor building wire made with soft-drawn, annealed copper strands and insulated with thermoplastic PVC. Rated at 600 volts, this 4 gauge wire delivers consistent power in both residential and commercial electrical systems. Designed to withstand up to 75°C in dry or wet conditions, it is well-suited for use in conduit, duct, and other raceway installations.

Applications of THW 4 AWG Copper Wire This stranded 4 AWG copper conductor is widely used for:

  • Power distribution in industrial and commercial buildings
  • Subpanel feeders and service entrance wiring
  • Lighting and HVAC circuits
  • Underground conduit installations
  • General-purpose building wiring in wet and dry locations

THW 4 AWG offers a balance of high ampacity and flexibility, making it ideal for medium-capacity circuits requiring durability and long-term performance.
