Waterproof Ground Power Distribution Terminal Block Battery Bus Bar [Max. 300V AC/48V DC] [IP65] [Positive/Negative] Insulated Busbar for 12V Automotive Auto Vehicle Marine Car Trailer RV Boat

  • SOLID PROTECTION - Busbars installed in water prone areas require the kind of protection that most "universal" products just can’t handle.  Our fully enclosed, waterproof busbars shield your wiring against water intrusion and accidental shorts.
  • BUILT BETTER - You take pride in your project, we take pride in our product. We use copper, not brass, for improved conductivity and corrosion resistance.  And the box is heavy-gauge nylon, not cheap plastic, for better heat resistance and longevity.
  • A COMPLETE KIT - Our busbar includes all of the seals, terminals and mounting bolts you'll need to get the job done. We even include a 2' 4 AWG power wire; because there’s nothing worse than missing that one small part you need to finish a project!
  • BUILD WITHOUT BARRIERS - Your equipment should never hold you back; and these junction blocks don't. With AC/DC Compatibility, carrying a 300V AC & 48V DC rating that supports up to 150A at 32V DC per bus, they are built to make your plans possible.
  • VERSATILE - Multiple mounting options simplify the install process. Mount it directly to any flat surface, use the included Z brackets to mount it to uneven surfaces, or even pair it with PWR0312 to create an incredibly powerful distribution center.

Clean, Reliable Power A power distribution block has one job - to distribute reliable power or ground to your electrical accessories. How well it performs that job depends directly on its ability to maintain clean and solid connections. The No.1 enemy of a clean junction point is moisture. Most distribution blocks leave your connections open and exposed to the weather; but not this one. The IP65 rated waterproof protection keeps your connections bone dry and completely protected, even in water prone marine and off-road applications. More Power At the core of our powerful distribution blocks is a heavy-gauge, tin-plated copper busbar. Unlike other products that use lower quality brass busbars, our copper bus provides superior corrosion resistance and conductivity. These boxes also feature a durable, heat resistant nylon housing that won’t become brittle and break when exposed to the constant heat of the engine bay. We even include a heavy-duty, 4AWG copper power wire to minimize voltage loss from your battery to your accessories. Works With You You’ve put so much work into your wiring, why should you compromise on your bus-bar location? Make your box work for you with our unique mounting options. Equipped with our unique, adjustable z-brackets you're free to mount your box on any flat, uneven, or odd-shaped surface.
