400 Amp Solid Copper Busbar 4 Stud (5/16" Zinc, Black) Common Bus, Terminal Block

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 !

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.

Compared with the cheaper busbars on the market the solid copper plate is a much better conductor of electricity so there’s no loss of energy. Included mounting screws and cover plate as a nice bonus. Very well built.

Well built, industrial grade busbar. Perfect 400 amp for my RV solar system. Easy to install, comes with all hardware. So glad I found this. Love that it's assembled in the U.S.A.

Great Quality! Will recommend this product to friends.
