Reduce the chances of electrocution from your on board DC system.We strongly recommend using Ancor Marine Grade Safety Duplex Cable in your boat's DC system. The familiar red and black conductors are now red and yellow (correctly color-coded to ABYC standards), to reduce the chance of incorrectly connecting the AC hot (black) with the DC ground (black). The white common jacket is made for easy removal, while providing excellent abrasion resistance.These cables exceed UL 1426 standards and are made from the highest quality, ultra flexible (Type 3/Class K) tinned copper stranding for maximum protection against corrosion and electrolysis while resisting fatigue due to vibration and flexing.The premium vinyl insulation is rated at 600 volts, 221F (105C) dry and 167F (75C) wet, stays flexible even in extreme cold (-40F/C) and resists saltwater, battery acid, oil, gasoline, heat, abrasion and ultra-violet radiation for peace-of-mind in harsh marine environments.SpecificationsWire Type: SafetyConstruction: Tinned CopperConductors: One Red, One YellowColor of Exterior Insulation: WhiteVoltage Rating: 600VDry Rating: 221F (105C)Wet Rating: 167F (75C)Cold Rating: -40F/CApprovals: UL 1426, ABYC, CSA
