Waterproof plugs and sockets are a critical component in maintaining the integrity of your boat's electrical system, protecting it from the harsh marine environment. Whether you're powering 12V devices or managing larger 220V loads via shore power hookups, a watertight connection is paramount. We offer a comprehensive range of solutions, from inline plugs to panel-mount sockets, with various IP protection levels.

Choosing the right model depends on the amperage and number of poles required. Always verify compatibility with your existing wiring and ensure the chosen plug or socket can handle the maximum current draw of the connected device. Undersizing can lead to overheating and, in the worst-case scenario, a fire.

Waterproof Plugs and Sockets: Materials and Standards



The most common materials are UV-resistant and saltwater-resistant technopolymers. Some models, especially those for heavy-duty applications, feature nickel-plated brass contacts for enhanced conductivity and corrosion resistance. Pay close attention to the IP (Ingress Protection) rating: the higher the number, the greater the protection against dust and liquids. An IP67 rating indicates complete protection against dust and temporary immersion in water.

The Officina Basile Recommendation




  • Regular Inspection: Even the most robust waterproof plugs and sockets require periodic checks. Inspect the integrity of the seals and the cleanliness of the contacts.

  • Replacement: If you notice any signs of corrosion or damage, replace the plug or socket immediately. Don't risk a short circuit or system malfunction.

  • Compatibility: When replacing a plug or socket, ensure it's compatible with the rest of your system and that it can handle the required amperage.



Consider also installing a residual current circuit breaker (RCCB) or ground fault circuit interrupter (GFCI) to protect your electrical system. You can find these in our dedicated section for circuit breakers and fuses.

FAQ



What gauge wire should I use for a 12V waterproof socket powering a portable refrigerator?


The wire gauge depends on the power of the refrigerator (in Watts) and the length of the wire run. As a general rule, for a standard portable refrigerator (approximately 50W) and a wire length of less than 3 meters, a 2.5 mm² (approx. 14 AWG) wire is sufficient. If in doubt, consult a marine electrical wiring sizing chart or consult a qualified electrician.



Are all waterproof plugs and sockets the same? Can I use a garden-variety plug on my boat?


Absolutely not. Waterproof plugs and sockets for marine use are specifically designed to withstand the marine environment, characterized by salt spray, humidity, and vibration. Using a garden plug (even if seemingly waterproof) can compromise the safety of your electrical system and cause corrosion and malfunctions.



How can I further protect my waterproof connectors from corrosion?


In addition to regular maintenance, you can apply a thin layer of dielectric grease to the contacts to prevent oxidation. Also, ensure that the sockets are installed in locations sheltered from direct spray and rain.
