3/0 Gauge (AWG) Battery Cable has an amperage capacity of 300 amps at a cable length of around 15 feet. 3/0 gauge battery cable is often used in main power applications heavy trucks, utility vehicles, large RV's and large water crafts. Also great for high capacity solar cable applications. The total length of both the positive and negative cables have to be considered when selecting amperage capacity of a 3/0 gauge cable in your electrical system. Made from 99.9% pure copper strandscovered in a durable, high temperature resistant PVC insulation. The average outside diameter of the cable is approximately 0.700 inches. Rated for low voltage and battery use up to 60 volts DC and 25 Volts AC. The internal copper stranded core is highly conductive maximizing current flow while still being highly flexible. Meets SAE J1127 specifications. Temperature rated from -50°C to 105°C (-58°F to 221°F). Made in the USA. RoHS Compliant.
