This 50A shore power plug is engineered for vessels with significant electrical demands. Its robust construction and high-quality components provide low resistance and minimal heat generation while transferring large loads – critical for safety during operation. The polycarbonate body not only withstands physical impact but also prolonged exposure to UV rays and salt spray without degradation or cracking. The plug mates with standard 50A boat inlets (deck mounted male connectors) following the common international marine standard. When properly connected, it creates a secure, vibration-resistant link, and the locking mechanism ensures it won’t loosen even under motion or tension.
- Use Cases: Recommended for large yachts (typically over 45 feet) and small ships outfitted with multiple electrical systems – e.g., several air conditioners, electric stovetops, high-capacity battery chargers. This plug delivers the necessary amperage to run all these systems simultaneously when connected to shore power, ensuring your vessel has full electrical functionality dockside.
- Operational Safety: Always switch off the shore power source (turn off the pedestal breaker) before plugging in or unplugging the 50A connector. This prevents arcing and the risk of electric shock. Once plugged in, firmly secure any locking ring or collar to the boat’s inlet for maximum water resistance during use.
- Maintenance & Reliability: Periodically inspect the plug’s contact pins – they should remain clean and free of burn marks. The silver plating on the pins helps resist oxidation, but if the plug will be unused for long periods, applying a light coat of dielectric grease can provide extra protection. With proper care, this plug will perform reliably for many years without loss of conductivity or overheating.
- Additional Protection: For complete waterproofing when the plug is not in use, attach an IP56/67 protective cap (available separately). This keeps the plug’s prongs dry and clean, extending the component’s lifespan. When the plug is connected, ensure that the seal between the plug and the boat inlet is in place and intact – this gasket is crucial for keeping moisture out of the connection.
