Blue Sea Systems 1991 PowerBar 1000 Stud with Cover, 12 x 3/8"

These bus bars are SUPERB. They have a lot of copper in them, as they are a bit heavy. I purchased the 12 x 3/8 for an extremely good price here on Amazon. Well built, and you can combine two for a negative and positive bus on one bar. The covers are semi-clear and very durable. As shipped they snap on. I will say, they are not easy to remove with just your bare hands. It appears you can also use screws to attach the covers. Extremely little to no resistance across the bar and from the farthest terminals; my multimeter had trouble detecting any.The larger terminals are perfect for interconnecting batteries in parallel and connecting large inverters, while the smaller ones are great for attaching small meters, direct-voltage lighting, or accessories. And at 1000 amps, I have yet to be able to throw enough amps at it to even come close to its limits.I use these in a solar system as a default point of connection for my battery bank, charge controller, inverter, and for lighting/accessories. These have quickly become the very heart of the system as all power passes through these.Highly recommended.

Very substantial power bar. There is no question as to its robustness. We’ve actually drawn 1400 amps at 24vdc for short duty cycles without any issues.

$162.04 is just WAY too much for a machined piece of metal with a few studs and screws with plastic end caps Isolating the power bar. If I could go back in time I would NOT have ordered this and just made my own common power points with some wood and bolts. It would have saved me hundreds of dollars.

It is very shiny and seems to work well.

These PowerBars are AWESOME! They are very heavy and rugged and the lugs easily handle the heaviest of 4/0 cables. I wound up buying another pair because they look so darn nice and made running the heavy cables a little easier.

I use them directly in solar systems that I have on my property, I have a 52 KWp solar system with 6 inverters in parallel, everything is connected to two BUSBARs, one that I use as positive and the other as negative. The total I have managed to get through is 830 Amp x 56.8 Volts = 47 Kwp direct from the solar panels to the battery system. But this has not even heated up, it has not risen in temperature or anything like that. AWESOME PERFORMANCE.NOTE: I rarely leave a review for a product, but this one deserves it in every way.

I have 3 1000 5/16 Blue Sea Power Bars for My Solar System one is still free for my 20 amp AGM 100 Ah Backup Batteries... Other i have other Busbars and there is No Comparison.These come with Covers...These parallel my 3 @ 24v 200 Ah Weize Lifepro 4 Battery Banks.
