250 MM THHN/THWN-2 – High-Capacity Feeder for Large Commercial and Industrial Power Systems

This 250 mm² THHN/THWN-2 copper building wire is engineered for high-capacity power distribution in large commercial buildings and industrial facilities. It features a pure copper conductor (stranded or solid), PVC insulation with a nylon jacket, and UL83 certification. Rated 600V. The substantial cross-section provides ample ampacity for large loads while minimizing voltage drop over extended runs. The nylon jacket protects against abrasion and moisture during installation and throughout service life. This wire is specified for service entrances, main switchboard feeders, and high-capacity industrial equipment connections.

FAQ

What size conduit for 250 mm² conductors?

2-1/2" or 3" conduit depending on the number of conductors. The large outer diameter of 250 mm² requires careful conduit planning.

Can 250 mm² be used in parallel runs?

Yes. 250 mm² is often used in parallel configurations for very large services. Two or more parallel 250 mm² conductors can be used to achieve higher ampacity while keeping each conductor manageable.

What is the weight of 250 mm²?

Approximately 2.4 kg/m for stranded copper. This requires proper support during installation and pulling equipment with adequate capacity.

Is 250 mm² available with special colors?

Standard colors like black, red, blue, and white are available. Special order colors may have longer lead times.
