Duplex Boat Cable is a type of boat cable used in DC circuits and low-voltage AC applications. Pacer manufactures 8 AWG Duplex boat cable in-house in Sarasota FL, USA to ensure the highest level of quality. It begins by using finely stranded, Type III tinned copper conductors. These allow for maximum flexibility and they help to prevent corrosion at the same time. The PVC jacket helps 8 AWG Duplex Boat Cable with flexibility. It also serves to prevent moisture or air from building up. How is that done? During the extrusion process, the voids between wires are completely filled. This process leaves no room for moisture or air to accumulate. To make this even better, a talcum powder coating is applied to the interior wires. This coating allows for the easy removal of the outer jacket. Just another reason 8 AWG Duplex boat cable is perfect for marine usage.This Duplex Boat Cable (EDMO# W8/2RYW-50) is 8 AWG, has red and yellow cables with a white jacket, and comes on a 50 ft spool.
