What does "fishing" wires involve in the context of marine electrical work?

Fishing wires refers specifically to the technique of pulling wires through constrained or tight spaces within a vessel's electrical system using specialized tools such as a fish tape. This process is essential in marine electrical work, particularly when installing new wiring or replacing existing wires in areas that are difficult to access, such as behind bulkheads or in conduits.

Using a fish tape allows technicians to navigate around bends and corners effectively, ensuring that the wire is fed through the desired path without damaging existing wiring or other components. The fish tape acts as a guide for the wire, making it easier to install connections properly and reduce the risk of kinks or breaks in the wiring.

Measuring wire lengths accurately, repairing damaged wiring, and identifying wire types may be important tasks in marine electrical work, but they do not specifically relate to the process of navigating and pulling wires through confined spaces, which is what "fishing" wires entails.
