2Pcs Ground Bus Bar Terminal Block, Terminal Positions Wire Screw Terminal Brass Electrical Grounding Bars Block

These bus bar terminal blocks are well made and exactly what I needed for organizing ground wires. The brass construction feels heavy duty and conducts well, and the screws tighten firmly without stripping. Each position holds wires securely and gives a reliable connection. Installation was straightforward, and the blocks mount cleanly in a panel. They’ve handled multiple wires without bending or loosening, and the layout keeps everything neat compared to messy bundles of wires. With two in the set, there’s plenty of capacity for small or medium projects. A simple and effective grounding solution that feels durable enough to last

Great Item, super fast shipping

just the size I needed, works great

So its a good unit overall and great quality for the price, its super easy to connect wires to it, and it's easy to install.

They're cheap, and insulated from the mounting screws. Only 6 ports (and one use used to connect 'upsteam' but AWG-6 wire can fit those ports. For safety grounding of circuits below 40A, this is very good. If used as a "Neutral Return" in USA 120/240 household box connections, however, I would users to follow two configuration recommendations: #1, If you are going to use it as a split-phase USA 120/240 box, try to mix the connections of return current carrying "white" wires so that the circuits originate from BOTH of the main panel "hot" bus bars. When circuits from both of those "hot" busses are active at the same time, the return current amps cancel out within the bus bar -- reducing current on that shared #6 return wire, and reducing resistance for both paths. #2, Put the one (or maybe 2) master return "white wires" wires near the center of the bar, rather than one of the end ports. There will be fewer thin sections for current to traverse from "downstream" wires to the upstream master. - - - I do not recommend this bar for non-zero voltage connections, because it is not insulated from accidental touching.

Does what it needs to do. No obvious issues

Solidly built. Worked nicely connecting two 10ga stranded wires and a 18ga solid wire. Needed to pull a very low corrent draw off a solar array power output line.

I am giving four stars because of the screws are easy to strip out the head when tightening down. I used 1/4 x 1” hex head sheet metal screws to fasten down to my box which work well. I used 8 AGW and 10 AGW stranded wire for my solar project. I think #6 may fit but again it’s difficult to torque down without stripping the heads. It did work for my needs but i may go to an electric supply house next time.
