This 8 AWG marine wire is manufactured in-house in Sarasota FL, USA to ensure the absolute highest level of quality. This wire is constructed from Type III class K tinned copper. It is designed to offer excellent flexibility and durability. The copper conductors are tinned to resist corrosion. This process adds to the life of the wire. What type of insulation is used during the manufacturing process? Well, once the copper is tinned, the next part of the process insulates the wire. This insulation adds a PVC jacket that is flexible and durable. It is designed to protect the wire and make it resistant to a variety of hazards.
