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

In marine applications, stranded wire is often chosen for its flexibility and ease of installation. However, one of the concerns with using stranded wire is its susceptibility to corrosion. The strands of wire are typically made up of multiple smaller wires, which creates more surface area that can come into contact with moisture, salt, and other corrosive elements commonly found in marine environments.

Over time, this exposure can lead to corrosion, which deteriorates the wire's conductance and can potentially cause electrical failures or short circuits. This is particularly concerning in marine environments where wires are often subject to constant exposure to seawater or high humidity, making corrosion a critical issue to consider when selecting materials for electrical systems on boats. Proper insulation and protective coatings are essential to mitigate this risk, but it remains a significant factor when evaluating the suitability of stranded wire for marine applications.
