This 4 AWG THHN building wire provides a stranded copper conductor with thermoplastic insulation and a nylon jacket. The stranded construction offers increased flexibility compared to solid wire, which simplifies pulling through conduit and reduces stress in applications requiring movement or vibration. This specific wire is rated for 600 volts and suitable for general purpose wiring.
Commonly used in conduits, cable trays, and service entrances for industrial and commercial applications. The nylon jacket provides abrasion and chemical resistance, extending service life in harsh environments. It maintains electrical integrity under dry and wet conditions.
