500A Marine Bus Bar 48V Power Distribution Block

The heavy-duty foundation you need to safely distribute serious power across your 12V to 48V systems. Built around a massive 6mm pure copper plate, this distribution block easily handles a continuous 500A draw, guaranteeing minimal voltage drop and keeping temperatures down even when you're pushing your gear to the limit.

Designed with a modular box casing, it features rubber-gasketed inlets and outlets to lock out dust, mud, and water, while preventing accidental shorts and contact. Whether you're rewiring a tinny, setting up a caravan lithium bank, or decking out the back of your 4x4, this kit gives you a clean, bulletproof connection for all your heavy-gauge cables.

Problem Solving / Benefits

• Eliminate dangerous bird's nest wiring: Consolidate all your heavy-gauge cables into one safe, secure modular box so you aren't hunting down loose connections on corrugated outback tracks.
• Safely run power-hungry gear: With a massive 500A continuous rating, you can run big 3000W inverters and winches simultaneously without melting your terminals or suffering massive voltage drop.
• Protect connections from the elements: The tough housing with rubber wire gaskets seals out water, dirt, and dust, preventing corrosion and shorts on marine setups or dusty touring rigs.
• Simplify your dual battery build: The package includes both positive and ground distribution blocks, making it dead simple to wire up complex setups in your canopy or camper trailer.

Key Features

• Extreme 500A Capacity: A 6mm thick pure copper plate ensures maximum conductivity and safely handles up to 500 Amps of continuous DC current.
• Versatile 6-Stud Design: Features four M8 (8mm) studs and two massive M10 (10mm) studs to accommodate various heavy-duty cable lugs and wiring configurations.
• Weather-Sealed Housing: The modular box design includes tight rubber grommets at the wire entry and exit points for serious dust and water protection.
• Universal Application: Rated for up to 48V DC, making it perfect for modern high-voltage lithium solar setups, marine applications, RVs, and 4x4s.
• Complete Kit: Comes with both a positive and a negative (ground) distribution block so you can overhaul your entire electrical system at once.
