What is a potential issue with using stranded wire in marine applications?

In marine applications, using stranded wire can present a concern regarding corrosion, particularly because the individual strands of the wire can create more surface area exposed to moisture and other corrosive elements found in the environment. Stranded wire is composed of multiple small wires twisted together, making it more flexible, which is beneficial for routing in tight space; however, this feature also means that there are more potential sites for corrosion, especially when exposed to saltwater and other harsh conditions commonly found in marine settings.

When stranded wire is used, it’s crucial to ensure that it is properly insulated and, ideally, coated with a material that can resist corrosion. Otherwise, the integrity of the electrical connections may degrade over time due to oxidation, which can result in increased resistance, potential overheating, or even failure of electrical systems. This is particularly critical in marine environments where consistent performance and safety are paramount.
