UL83 THHN wire for feeder circuits

THWN-2 Copper Conductor for Conduit and Raceway Projects

GERITEL WIRE feeder wire is designed for buyers who need a dependable 600V single-conductor building wire for organized electrical installation. The typical construction combines a copper conductor, heat- and moisture-resistant PVC insulation and a nylon sheath, giving the wire the recognizable THHN/THWN-2 profile used in conduit and raceway work. When THWN-2 copper conductor is part of the project specification, this construction can support conduit, raceway, feeder and branch-circuit wiring under the applicable installation rules. GERITEL WIRE supports size confirmation, color selection, OEM printing, coil or reel packaging and export documentation so distributors and project buyers can place repeat orders with clearer specifications.

FAQ

Can I request custom insulation colors?

Custom colors may be possible for project or distributor orders, but certification markings, manufacturing minimums and production scheduling should be confirmed first. GERITEL WIRE can quote custom color THHN wire based on the actual project BOM rather than relying on a generic product name, helping reduce specification mismatches.

Does color affect electrical performance?

Color is primarily used for conductor identification. Electrical performance depends on the certified insulation system and conductor construction rather than the visible color alone. For international orders of THHN wire colors, GERITEL WIRE can coordinate technical confirmation, color and size selection, printing, packing and shipment documentation.

Can different colors be mixed in one order?

Yes, mixed-color project orders are common when circuits require several phase, neutral and grounding colors. Packaging and labeling should clearly separate each item. GERITEL WIRE can support multi color THHN wire distributors and contractors with product-data confirmation, OEM requirements, batch identification and export-ready packing.

Can the wire be printed with sequential length markings?

Some manufacturers offer sequential footage or meter markings on certain sizes. This is a value-added feature that should be specified in the purchase order if required. GERITEL WIRE supports THHN sequential footage marking project inquiries with specification review, OEM marking discussion, reel or coil planning and export documentation.
