High Conductivity: Geosiry wires are made of high-precision oxygen-free tinned copper, with 26 strands of 0.254 mm tinned copper wire in each circuit, which has lower resistance and higher conductivity than aluminum. Product Specifications: Gauge: 16, Waterproof Level: IP68, Rated Voltage: 300V (also for 5V, 12V, 24V to 300V). Rated for operating temperatures from -104°F to 176°F. Flame Retardant Rating: VW-1. High Quality Material: 16 gauge wire is insulated/jacketed with high quality PVC for excellent chemical and oxidation resistance to protect wires from damage caused by abrasion, wear, and moisture. Easy to Use: 16 awg wire is made of flexible PVC insulation and can be bent in any direction, and is easy to strip, solder, crimp terminals, connect, cut, and wrap around necessary components, enough to fit in tight spaces. Wide Range of Applications: 16/2 wire can be used as low voltage wire, speaker wire, LED wire, power cord, indoor light cable, automotive wire, landscape l
