GS Power 12 AWG Duplex Marine Wire - 50 Ft Tinned Copper Boat Wiring

GS Power 12 AWG Duplex Marine Wire - 50 Ft Tinned Copper Boat Wiring

• Tinned Copper Construction: Each conductor is built from 2x67 strands of 0.25mm oxygen-free tinned copper, rated to 600V for demanding low-voltage circuits. The tin coating resists corrosion from salt spray, moisture, and battery acid, extending wire life in marine and outdoor environments. Inside the white PVC outer jacket, red and black conductor sheaths make polarity identification instant; the white jacket also makes routing easier to trace during installation and inspection
• Rated for Demanding Circuits: This 12 AWG duplex wire is rated to 600V with insulation tested to 105°C/220°F dry and 75°C/167°F wet, meeting ABYC E-11 performance requirements for marine electrical systems. Amperage capacity depends on installation variables; consult ABYC ampacity tables or a marine electrician to confirm sizing for your circuit. GS Power also offers this wire in 10, 14, 16, and 18 AWG so you can select the right gauge for your amperage requirements
• Versatile 12V Applications: Wire trolling motors on bass and jon boats, RV solar panel circuits, trailer brake lights, fish finders, marine stereos, and onboard lighting with a single 50-foot roll that stays flexible at -40°F/-40°C for cold-weather installs. Measure all planned wire runs before ordering; bulk spool options are available for larger projects. This duplex cable handles 12-volt low-voltage wiring from coastal boats to enclosed trailer and automotive builds
• Meets Marine Safety Standards: This marine grade wire meets ABYC E-11, SAE J1127/J1128, and US Coast Guard 33 CFR Part 183 requirements, and is built to UL 1426 marine cable specifications. Type III 26/0.0100 ultra-flexible stranding delivers the suppleness needed for tight routing in engine compartments and bilge areas. The conductors are oxygen-free tinned copper, not aluminum, ensuring reliable conductivity and long-term corrosion resistance in certified marine installations
• Built for Harsh Environments: Wet-rated insulation (75°C/167°F) and Coast Guard-compliant construction make this wire suitable for demanding marine locations, including bilge-adjacent runs. The PVC jacket and tinned copper conductors resist salt water, battery acid, oil, gasoline, heat, abrasion, and UV radiation. Wire stays flexible at -40°F for winterized storage; the 12 AWG stranded construction accepts standard crimp-style connectors sized for 12 AWG
