THW-2-LS/THHW-LS 600V 90C 14AWG 12AWG 10AWG 8AWG 6 2 1 1/0 2/0AWG Copper Wire​ The THW-2-LS and THHW-LS copper wire series stands as a high-performance solution for demanding electrical systems, combining safety, durability, and versatility. Rated for 600V and 90°C (dry/wet), these wires span a broad gauge range—14AWG to 2/0AWG—catering to diverse power needs, from light-duty circuits (14AWG) to heavy industrial loads (2/0AWG).​ THW-2-LS features low-smoke (LS) PVC insulation, ideal for enclosed spaces where fire safety is critical, resisting moisture and abrasion while minimizing smoke emission during incidents. THHW-LS enhances heat tolerance, suited for high-temperature environments like industrial furnaces or HVAC systems, with the same LS benefit.​ Stranded copper conductors ensure flexibility for easy installation in tight spaces, while 100% copper composition guarantees efficient conductivity, reducing energy loss. Compliant with industry standards, these wires excel in commercial, industrial, and residential heating applications, offering a reliable choice for professionals prioritizing safety, performance, and adaptability across varying power demands.
