Parts Desk Insights
Best Use Case: Ideal for duplex marine wiring runs on boats where flexible, flame-retardant, tinned copper cable is needed—especially in areas that require easier routing due to the cable’s flexibility.
Common Issues: Common install issues include nicking insulation when routing through sharp edges and skipping proper strain relief at terminations. When replacing duplex runs, double-check that you maintain the intended conductor polarity/color (red & yellow) and use compatible marine-grade terminals/connections for tinned copper.
