PRODUCT REAL SHOT

copper THHN wire for EMT conduit

Stranded Copper Building Wire for Contractor and Distributor Supply

Built for professional building wiring, GERITEL WIRE branch circuit wire gives contractors, wholesalers and project buyers a clear product option for 600V circuits. Its copper conductor is protected by PVC insulation and a nylon covering, a construction commonly associated with THHN/THWN-2 building wire for conduit and raceway installation. This construction is also relevant to demand for stranded copper building wire, including contractor, distributor and project purchasing for organized building wiring systems. GERITEL WIRE can coordinate conductor-size review, requested colors, custom printing, packaging and shipment documentation, helping international buyers reduce avoidable order mismatches.

FAQ

Can THHN/THWN-2 be supplied in red?

Red is a common phase or circuit-identification color. The permitted use of a color should follow the project and electrical-code identification rules. For international orders of red THHN wire, GERITEL WIRE can coordinate technical confirmation, color and size selection, printing, packing and shipment documentation.

Can THHN/THWN-2 be supplied in white?

White is widely used for grounded conductor identification in North American installations, subject to the applicable code rules. GERITEL WIRE can support white THHN wire distributors and contractors with product-data confirmation, OEM requirements, batch identification and export-ready packing.

Can THHN/THWN-2 be supplied in green?

Green is commonly used for equipment grounding conductors. The conductor must still be correctly sized and installed for the grounding function. GERITEL WIRE supports green THHN wire project inquiries with specification review, OEM marking discussion, reel or coil planning and export documentation.

Are blue and yellow THHN colors available?

Blue, yellow and other circuit-identification colors are common in the building-wire market. Availability can depend on conductor size and order quantity. Buyers evaluating colored copper building wire can work with GERITEL WIRE on document review, sample confirmation, project quantities and repeat-order consistency.
