A bulkhead connector is an electrical device designed to allow safe and watertight passage of electrical cables through a bulkhead, wall, hull, or deck. It protects the cable from abrasion and mechanical damage while maintaining the structural integrity and watertightness of the surface being penetrated.

The BLUE SEA 2204-BSS through-hull connector is used to safely route high-current cables through hulls, decks, and bulkheads of vessels. It prevents cable chafing against the structure and provides strain relief, improving the longevity and reliability of the onboard electrical installation.

This specific model, the BLUE SEA 2204-BSS, is red in color.

The 2204-BSS connector is made from robust, corrosion-resistant materials. Its studs are made of tin-plated copper alloy for excellent conductivity and resistance, while its base is made of reinforced thermoplastic (Zytel PA66 FR50NC010) for optimal insulation and durability.

The IP66 rating means this connector is fully protected against dust ingress (first digit 6) and can withstand powerful water jets from any direction (second digit 6). This makes it particularly suitable for marine environments where water exposure is common.

Tin-plated copper alloy studs offer several advantages. The tin plating improves corrosion resistance, a critical factor in saline marine environments. It also ensures excellent electrical conductivity and better durability of connections compared to unplated materials.

Yes, this connector is designed to withstand harsh marine environments. It features tinned copper alloy studs resistant to corrosion, a reinforced thermoplastic base, and an IP66 rating, protecting it against dust and powerful water jets.

The integrated strain relief in this connector’s design helps prevent mechanical stress on cables and their connections. By reducing tension at the connection point, it minimizes the risk of cable breakage or terminal loosening, thereby improving the reliability and safety of the electrical installation.

This BLUE SEA 2204-BSS through-hull connector has a maximum DC current capacity of 250 amperes (250A DC).

The 2204-BSS connector is designed to withstand a maximum voltage of 48 volts direct current (48V DC).

This connector uses 3/8"-16 UNC studs. This means a 3/8 inch diameter with a 16 threads-per-inch coarse thread pitch (Unified National Coarse).

Yes, absolutely. With a maximum voltage of 48V DC, this connector is perfectly suited and safe for use in 12V and 24V marine electrical systems.

No, this connector is specifically designed for direct current (DC) applications with a maximum voltage of 48V DC. It is neither recommended nor certified for use with alternating current (AC) systems.

This connector is particularly suited for installations requiring high-current cable runs, such as those for windlasses, electric winches, and other demanding marine electrical equipment.

For installing the 2204-BSS connector, a hole saw of Ø 24mm or Ø 7/8" (.875") diameter is recommended.

The large mounting face of the connector allows the use of a gasket or appropriate sealant to ensure a watertight installation. It is recommended to use marine-grade sealant or a watertight gasket compatible with the marine environment to seal the connector's perimeter once installed.

The recommended torque for the studs of this connector is 11.3 Nm (Newton-metres) or 100 in-lb (inch-pounds). Adhering to this torque ensures a stable and secure electrical connection.

This bulkhead pass-through is designed for high-current cables. Cables must be fitted with eyelet terminals or terminals suitable for 3/8"-16 UNC studs for a correct and secure connection.

For installation, you will generally need:

A 24mm or 7/8" hole saw for drilling the mounting hole. A torque wrench to apply the recommended tightening torque of 11.3 Nm (100 in-lb) on the studs. A wrench or socket suitable for 3/8"-16 studs. Marine sealant or a sealing gasket to ensure waterproofing.

The maximum bulkhead thickness depends on the available length of the studs once the connector is assembled and the connection accessories (terminals, washers, nuts) used. The technical drawing indicates a total stud length of approximately 79.4 mm (3.13 inches). It is essential to ensure there is enough threading left to securely fasten the cables on both sides of the bulkhead.
