Review: Star Point Grounding - I used 3 of these to rewire a 72 Nova and used a star point grounding technique, with 8awg wire connecting the battery to each ground block, avoiding all the grief of bad grounds. Plenty of room, good quality, reasonable price, easy top access with a cap that stays on. I'm not excited about using these for concealed power distribution on the positive side because of potential exposure or shorts without creating some sort of wrap around them, but on the ground side these are great. I decided to buy 4 more of these to rewire a friends classic car ground system next. Plain ring terminals with separate heat shrink worked best to fit the most grounds on all terminals and stack if necessary.
Review: Great flexible cover. - The flexible cover on the negative ground block, from the Online LED Store, won’t break if something hits it. As you can see I added some male quick connect terminals. So all I need to do is connect a ground wire, mount it to the fire wall. And it’s ready to connect off road lights, and put the cover on to protect thing’s from fire and electrical shock. This heavy duty ground block will keep your electrical wiring neat,,,no more spaghetti wiring. I highly recommend this product.

## Features

- START WITH THE BEST - Every successful project starts with a solid foundation. These sturdy junction blocks feature a robust, tin-plated brass busbar, a flame-resistant base, and durable stainless steel hardware.
- TRULY UNIVERSAL - In order to work wherever you might need it, we designed each busbar to handle up to 300V AC, 48V DC, and 150A at 32V DC (4,800W). So whether your working on a boat, a car, or an RV, we've got you covered.
- YOU'RE COVERED - What's the first thing that always breaks on a busbar? The cover. They're usually thin, rigid, and brittle. Not these covers. Our covers are flexible, flame-resistant, and aren't held on by tiny, breakable clips or easy to lose nuts.
- WORKS WITH YOU, NOT AGAINST YOU - Extra tall cover cutouts give you maximum flexibility with minimal effort. Use whatever gauge wire you need, route your wires from either side, double-stack wires if necessary, the covers will still fit.
- SIMPLE - Sometimes "more options" just means more difficult. Our power and ground 12 terminals, 4-1/2? distribution block gives you everything you need without overcrowding your system, or your patience.

## Questions & Answers

**Q: Bus bar [max. 300v ac/48v dc] neg/pos. <<<< can i connect this to my 12volt dc car battery as an aux connection?**
A: I don't see why not, just make sure your connectors and cable are rated for the current.

**Q: Can these be used to branch out a 120volt residential line to 6 LED pendant lights?**
A: Yes.  Limited at 15A 110AC.  Hope this helps.

**Q: Can i use these for 110Volts to power security cameras and lights? and**
A: Yes. Red is hot, black is common. No stud for green wire ground.

**Q: Can this be used to connect multiple batterys into one power source?**
A: In theory yes, but remember that if connecting batteries in series you will will need interconnect cables to increase voltage and if in parallel then you will need paralleling cables to increase amps. Additionally you will need over current protection for each positive connection to and from the bus bar. These bus bars can be used for connection from a single battery bank to power several components at once or from a charger to the batteries.
