DESCRIPTION
Secure High-Current Cable Routing for Marine and Automotive Systems
Managing heavy-duty power distribution in marine vessels, caravans, and 4x4 builds often involves routing thick cables through structural barriers. The Blue Sea Systems Feed Through Connector provides a professional, safety-focused solution for passing high amperage circuits through hulls, decks, and firewalls. Unlike simple rubber grommets that can degrade or dislodge over time, this rigid terminal post creates a permanent, secure anchor point that isolates vibration and prevents damage to your electrical system.
Designed for demanding environments, this red connector indicates a positive circuit connection, helping to maintain clear polarity identification within complex electrical banks. Whether you are wiring a dual battery system in a touring vehicle or setting up a main power bus on a boat, this device ensures your installation meets professional standards for safety and reliability.
Eliminate Cable Chafing and Electrical Short Risks
One of the most significant risks in vehicle and marine wiring is cable chafing. When large cables carrying high current are passed directly through holes in metal bulkheads or fibreglass decks, constant vibration can cause the insulation to wear through, leading to catastrophic short circuits or fires. This terminal feed through connector completely eliminates that risk by terminating the cable on either side of the barrier.
By providing a solid mounting point, it acts as effective strain relief, ensuring that movement in the cable run does not translate to stress at the pass-through point. This is particularly critical for heavy-gauge cables that are heavy and prone to shifting during transit or rough seas.
Marine-Grade Durability and High Conductivity
Built to withstand harsh saltwater environments, the unit features a tin-plated copper alloy stud. This material choice offers the optimal balance of high electrical conductivity and superior corrosion resistance, preventing voltage drop over time. The 5/16"-18 (Approx. M8) studs are robust enough to torque down securely on heavy-duty cable lugs, ensuring a low-resistance connection essential for high-current applications.
Rated for a continuous current of 250 Amps and compatible with systems up to 48V DC, this connector is suitable for a wide range of DC applications, including 12V, 24V, and 48V battery banks. The reinforced thermoplastic base provides high heat resistance and structural strength, ensuring the terminal remains secure even under thermal load.
Watertight Installation for Exposed Areas
For installations where water ingress is a concern, such as through a boat hull or an exterior vehicle bulkhead, this connector offers an IP66 rating when properly installed. The mounting face is designed to be gasketed or bedded with sealant, creating a watertight barrier that withstands heavy seas and high-pressure washdowns. This allows you to route power safely from exterior battery boxes or solar arrays into the cabin without compromising the watertight integrity of your vessel or vehicle.
- High-Current Capacity: Handles up to 250A continuous current, ideal for main battery lines and inverter supplies.
- Corrosion Resistant: Tin-plated copper alloy studs ensure long-lasting conductivity in marine conditions.
- Universal Voltage: Rated for up to 48V DC, making it safe for 12V, 24V, and 48V systems.
- Secure Mounting: 5/16"-18 (Approx. M8) stud size accommodates standard heavy-duty cable lugs.
- Safety First: Eliminates chafing risks and provides excellent strain relief for large cables.
- Waterproof Design: IP66 rated structure protects against powerful water jets and heavy seas.
Professional Power Distribution Made Easy
Upgrade your electrical installation with a feed-through solution that prioritises safety and longevity. By using a dedicated terminal post, you simplify maintenance, improve organisation, and significantly reduce the risk of electrical faults caused by physical cable damage.
Secure your power system today with this heavy-duty feed through connector and ensure a safe, watertight electrical pass-through for your vessel or vehicle.
