DaierTek 300A Bus Bar 12V Marine 12V Power Distribution Block with Cover 6 x 3/8" (M10) Terminal Studs Max 300V AC 48V DC Positive & Ground Busbar for Automotive Car Boat

I bought these as power distribution bus bars on one of my smaller solar power systems. These bus bars are made of tinned plated copper bus bars with a 300 amp rating. The bus bars are very strong with six 3/8" studs and protective covers. Great for heavy gauge cables moving lots of current. These bus bars are very capable and have high conductivity for a low resistance connection. If you want a great connection, make absolutely sure the bus bars are copper. They are very easy to install and have lots of room for expansion. These bus bars are a terrific value for the price. I highly reccomend them to anyone looking for good bus bars for solar, RV, Marine and other applications. I give them 5 stars.

Very heavy duty easy to mount wherever you would like material feels heavy duty, looks very nice and expensive but for the price you can’t beat it

Great quality. Running high amps there is no heat from the buss bar.

I am using these on my Boat and they have been absolutely great! installation was quick and easy. They are very durable and hold up well in the Florida humidity and salt air. The front plate is easily removable for installing and removing wires as needed. The design of this distribution block makes it easy to connect and remove wires in tight spaces.

Larger than you would expect and well built Would buy again for sure

These are a good price for a pair of 300A rated bus bars. The bars are quite thick and the bases feel very solid, yet without a taking up much space. I really like that they have six terminal instead of the much more common four terminals. I do wish the tops stayed on better and covered more of the terminals. They easily pop off. There's one curiosity. On the red bar, I could easily turn the outer terminal bolts by hand, which happened when tightening the nut, pushing the head of the bolt (underneath the bar) out through the plastic cover. This didn't seem right to me, and the black bar didn't have this 'feature'. I asked a question here on Amazon (which has mysteriously totally disappeared), and the seller said it might be a defect, but didn't sound so sure. They recommended I return and replace, which I did. So, the replacement set has this 'defect/feature' on both the red and black bars. I guess it's normal? I'll be putting some Loctite on those threads, since I do want to use all the terminals. The only possible reason I can see for these bolts to be left loose, rather than glued or epoxied in, is to allow for disassembly of the unit to replace the bolts, bar, or base. But if you're breaking any of those items, I think you need a better bar anyway.

Excellent, easy to handle and connect, I recommend it 100%

Much heavier duty than I originally expected which is a good thing. Wish it was at least copped plated but I new that before ordering.

Good

Excellent quality. Really solid bus bars.

Fantastic busbars. I'm in the process of installing Solar and a new inverter in my small RV. Having these busbars is way better that just bolting a couple of cables together. Its kinda amazing how many cables you can start putting together, plus it makes it easier to identify what goes where. Thanks again

Great value for money

Worked perfect for solar installation. Kept everything neat and tidy. Love them, would buy again!
