300A Heavy-Duty Bus Bar Power Distribution Block (M10/3.8″)
Organize and protect your high-current electrical systems with this Heavy-Duty 300A Power Distribution Block. Designed for demanding marine, automotive, and solar applications, this bus bar features a modular “box” design that simplifies complex wiring while protecting connections from accidental shorts.
Whether you are managing a 12V dual-battery system or a high-voltage 48V solar bank, this distribution block provides a robust, professional-grade solution for consolidating your power or ground wires.
Key Features
High-Current Handling: Rated for a continuous 300A current, making it ideal for high-draw devices like winches, inverters, and large audio systems.
Modular Design: The protective cover features removable windows on all four sides, allowing you to route heavy-gauge cables in any direction for a clean, unobstructed installation.
Extreme Durability: Built with a fiberglass-reinforced nylon base, offering exceptional mechanical strength and heat resistance.
Corrosion Resistant: Equipped with stainless steel studs and brass conductors to ensure maximum conductivity and longevity in damp or marine environments.
Flexible Voltage Range: Safely operates across DC systems from 12V up to 48V, providing versatility for RVs, boats, trucks, and off-grid power systems.

Installation Tip
When connecting heavy-duty ring terminals to the 3/8″ (M10) studs, always ensure you stack the largest/highest-current draw cable at the bottom of the stack (closest to the bus bar) for the most efficient heat dissipation and electrical contact. Ensure all nuts are torqued properly to prevent high-resistance “hot spots.”
