The Coleman Cable 51014 is a professional-grade 12 AWG solid copper wire designed specifically for demanding HVACR and industrial applications. This 500 ft spool of T90-Nylon and TWN75 building wire is engineered for high-performance power distribution in both residential and commercial branch circuits. Featuring a robust 600V thermoplastic insulation and a tough polyamide nylon jacket, it provides superior resistance against abrasion, moisture, gasoline, and oil (Gr II). As a veteran technician knows, the dual-rating ensures versatility: it is optimized for 90°C dry locations and 75°C wet locations, meeting strict CSA C22.2 No. 75 and Canadian Electrical Code requirements. The solid conductor construction ensures a secure fit in terminal blocks and eliminates the common fraying issues found in stranded alternatives during conduit pulls. Key Benefits: Dual-Rated Performance: Certified as both T90 for dry raceways and TWN75 for damp or wet environments. Extreme Durability: The nylon-jacketed insulation stands up to aggressive chemical exposure and mechanical stress during installation. Optimized Conductivity: Solid bare copper provides lower resistance and maximum contact surface for high-draw HVAC equipment. Simplified Pulling: The low-friction jacket reduces the need for excessive pulling lubricant in crowded conduit systems. Common Questions: What is the maximum amperage for 12 AWG T90 wire? In a dry environment at 90°C, the 12 AWG copper wire ampacity is rated up to 30A for derating purposes, though it is typically limited to a 20A circuit breaker per standard electrical codes. Is this cable suitable for direct burial? No, while it is moisture-resistant and rated for wet locations (TWN75), it must be installed within a approved raceway or conduit. Can this be used for gasoline pump wiring? Yes, the Gasoline and Oil Resistant II rating makes it suitable for locations exposed to these hydrocarbons. This item is not eligible for free shipping.
