4 Post Power Distribution Block Bus Bar with Cover - Made in The USA - 250 Amp Rating - Marine, Automotive, and Solar Wiring - Set of 2 (5/16")

Works great for when you need to hook up 2 or 3 series of batteries to your charge controller. I am sure it would work equally great for hooking up to 3 individual batteries also.

This thing seems rock solid. I may have gone with one size up (5/16) and probably could have used the smaller bolt size (1/4) or (3/8). The packaging was perfect for item and is Made In The USA. Another reason I went with this product. So far it is working great in my test environment and will be moving the components to my car soon. This block is running a 12V system with a power source, 3 amp and a DSP. Not sure if it shows but I also purchased the matching negative bus bar. Basically just the color is different. 4 gauge wire is being used for most with sized connections and heat wrap. So far I have been using this for a month of long term testing. One thing, just tighten the connections for a guaranteed solid connection when testing.

Very high quality. Worth the money for sure. Bigger than I expected. Used them to set up power for ATV accessories off of auxiliary battery.

Very good and very easy to use

This is good and sturdy other than the cover. I had no problems hooking up to 0awg and the bus bar was cool to the touch even after a 200amp load at 12v. If you add wires to the smaller connections you'll find it gets in the way of the cover which will have to be forced around it or cut. This is my reason for the star deduction.

Extremely well made.

I do a lot of electrical installs in trailers and small vehicles and this is one of the more well-built bus bars that I have purchased. Yes the case and mounting is plastic and a drawback is they do not supply you with mounting hardware which I would highly suggest the company to. Time will test the durability of the plastic housing but so far I have had zero issues with it done some testing and zero heat buildup like you get with some of these other cheap bus bars.. I would recommend that the company upgrade to a copper bus to eliminate any and all chance possible resistance or galvanic corrosion over time especially in more moisture prone environments. But it is extremely hard to find copper-based bus bars these days because copper is soft and a company's Sole Purpose to design a very durable device.. I will revisit this after I have thoroughly tested it.

I upgraded my old bus bar with this one as I upped my amperage, and it was now necessary to go with a larger one. It was very easy to replace the old one, as the form factor and holes lined up with the old one exactly. This bus bar is high quality and can handle up to 250 amps through four 5/16 posts. There are also three screws for connecting low amperage devices allowing for a total of seven connections. That was exactly what I was needing. I now have piece of mind knowing that this bus bar will handle everything I can throw at it. No warming, secure and safe connections with protective covers for added safety. This is marine quality for long lasting performance. It is top quality and I find it to be a terrific value for the price. I give this bus bar 5 stars.
