## Overview

This 400 Amp solid copper busbar features a 1/4 x 1" CDA 110 copper conductor with bright tin plating for maximum conductivity and corrosion resistance. Designed for 12-48V DC applications in RVs, marine, automotive, and solar setups, it supports continuous heavy loads without heating. The fully rebuildable ABS insulator and included mounting hardware provide stability and ease of installation, while zinc-plated Grade 5 fasteners and optional marine-grade stainless steel hardware ensure durability in harsh environments.

## Description

Solid copper BusBar for RV, boat & Marine, home, and automotive use in 12-48 volt DC applications. 400 Amp rated, continuous duty cycle, designed to meet increased ampacity requirements when 3000W 12V Inverters are fed by multiple sources through a common busbar, (solar, battery, generator, etc..) Fully rebuildable injection molded ABS Insulator is designed for maximum stability with a wide 4 hole mounting base, (mounting screws included), impact resistance, and rated working environment of -20 through 80°C, (-4 through 176°F) High quality materials used for studs, flange nuts, and mounting fasteners. Standard duty models use Grade 5 or higher, Zinc plated steel fasteners, and Marine rated models use 316 Stainless Steel hardware (316 stainless alloy is suitable for saltwater and corrosive environments whereas 304 stainless used by other manufacturers requires frequent cleaning)

Review: I have been building out my solar system for a few years now and admittedly used cheaper busbars which ended after I realized how poor they were as they warmed up significantly under heavy load. So I upgraded to these to connect my battery bank (6 Battery Packs - 1300AH of LFP, 3 packs per set of busbars) which can handle the loads and never get warm. The Busbar itself is quite thick to carry up to 600A, the base & cover are high quality and very strong, no flimsy cover. As the photo shows, the (+) Bar is offset from the wall by 3/4" which provides enough clearance to install MRBF Fuses and run the 4/0 wires without issues. Well worth the price !
Review: Great product. Heavy duty piece component of my DIY solar project. Made in USA. Highly recommended!

I am using this Busbar for a wiring project on an RV. I had ordered other busbars from other manufacturers and they were flimsy or easily cracked. This is a solid piece of equipment and very sturdy. I highly recommend this product.
