Parts Desk Insights
Best Use Case: A solid choice for marine electrical runs where you want flexible tinned copper to help limit corrosion risk in wet, salty environments and under vibration.
Common Issues: For best results, confirm you’re staying within your system’s wire gauge requirements (12 AWG) and use compatible marine-rated connectors/terminations. During installation, avoid nicking the conductor or jacket when stripping and route away from sharp edges to reduce abrasion wear.
