Application
THWN-2 12 gauge stranded wire is designed for a variety of electrical applications requiring high durability and reliable performance. This wire is commonly used in residential, commercial, and industrial settings, including for powering household appliances, HVAC systems, and in control panels. It is rated for use in both wet and dry environments, making it versatile for outdoor installations, underground wiring, or within buildings. With a temperature rating of up to 90°C in wet locations and 75°C in dry locations, this wire is ideal for installations that require resistance to water, oils, and other harsh conditions. THWN-2 is also compliant with National Electrical Code (NEC) requirements and can handle up to 600 volts, making it a preferred choice for a variety of electrical circuits.

Feature

THWN-2 wire is a high-performance electrical conductor designed for a wide range of demanding applications. It meets stringent industry standards, including UL 83 for thermoplastic insulation, and UL VW-1 for flame resistance, and is suitable for cable tray use in sizes 1/0 and larger. Manufactured to ASTM B1, B3, and B8 specifications, THWN-2 wire offers exceptional durability and conductivity, with a focus on reliability in wet and dry environments.
Certification
THWN-2 wire is a waterproof and high temperature resistant wire widely used in various electrical installations. Its "THWN" stands for thermoplastic insulation and underwater durability, while "2" indicates that the cable can be used in humidity conditions of 90°C. THWN-2 wire has passed multiple certifications, including UL (Underwriters Laboratory Certification), CSA (Canadian Standards Association) certification, and meets the standard requirements of NEC (National Electrical Code), ensuring its safety and reliability in wet or humid environments.
