4" Ground/Power Distribution Terminal Block Battery Bus Bar Set [Max. 300V AC/48V DC] Negative/Positive Insulated Busbar for Auto Marine Car Trailer RV Boat - Black/Red

START WITH THE BEST - Every successful project starts with a solid foundation. These sturdy junction blocks feature a robust, tin-plated brass busbar, a flame-resistant base, and durable stainless steel hardware.
TRULY UNIVERSAL - In order to work wherever you might need it, we designed each busbar to handle up to 300V AC, 48V DC, and 150A at 32V DC (4,800W). So whether your working on a boat, a car, or an RV, we've got you covered.
YOU'RE COVERED - What's the first thing that always breaks on a busbar? The cover. They're usually thin, rigid, and brittle. Not these covers. Our covers are flexible, flame-resistant, and aren't held on by tiny, breakable clips or easy to lose nuts.
WORKS WITH YOU, NOT AGAINST YOU - Extra tall cover cutouts give you maximum flexibility with minimal effort. Use whatever gauge wire you need, route your wires from either side, double-stack wires if necessary, the covers will still fit.
SIMPLE - Sometimes "more options" just means more difficult. Our power and ground 12 terminals, 4-1/2? distribution block gives you everything you need without overcrowding your system, or your patience.
