400 mm² THHN/THWN-2 for Large Industrial and Commercial Facilities
This 400 mm² THHN/THWN-2 copper building wire is designed for the most demanding power distribution applications. It features a pure copper stranded conductor (solid not typically available at this size), PVC insulation with a nylon jacket, and UL83 certification. Rated 600V. The 400 mm² cross-section delivers exceptional ampacity for large industrial loads, service entrances, and main switchgear connections. The nylon jacket provides robust abrasion resistance and moisture protection. This wire is commonly specified for utility service entrances, large transformer connections, and primary feeders in extensive commercial and industrial installations.
