How should wiring be protected from abrasion on a boat?

Wiring on a boat should be protected from abrasion primarily through the use of conduit or cable clamps. These methods secure wires while also providing a physical barrier that prevents them from coming into contact with sharp edges, moving parts, or other surfaces that could wear them down over time. Conduit acts as a protective sheath around the wires, absorbing impact and friction that might otherwise damage the insulation, which is crucial in a marine environment where exposure to elements and potential chafing is prevalent.

Cable clamps also serve dual purposes: they secure the wiring in place and help prevent movement that could lead to abrasion. These protective measures are essential for maintaining the integrity of the electrical system, ensuring safe operation and reducing the risk of electrical failures or shorts caused by damaged wires.

In contrast, leaving wires exposed can lead to increased wear and tear and potential short circuits. Using uninsulated wire could lead to hazardous situations, as there would be a lack of protection against electrical shock or short-circuiting. Burying wires within the boat structure might seem like a protective measure, but this method can complicate accessibility for inspections and maintenance, while also potentially trapping heat and moisture, which could negatively affect the wiring over time.
