MOFEEZPower Distribution Block Bus Bar, 4 x 3/8" Posts, 6 x #8 Screws Terminals, Max 48V 250A (Pair, Red & Black)

RV install

This are bigger than expected but I'm not complaining because they handled 170+ amps through individual lugs without heating much at all. The design is really nice, two of the lugs extend further than the others and hold the cover on with nylon insulating nuts. I made my own bus bars to connect laterally from the studs to some 200A breakers on each side, and didn't have any trouble setting everything up. This bus bar and it's screw terminals are overbuilt enough that when the lugs are tightened down, it feels like it becomes one solid piece with everything attached to it, with no wiggle or play at all.You can unscrew all of the smaller screw terminals which go down either side, leaving the entire surface around the large lugs free if you need more surface area for contact to handle higher amps. The plastic cover is also easy to trim with side cutters if you need a few more millimeters of clearance around the edges for large connections (it doesn't shatter unpredictably like bakelite would).

These were larger than I thought but worked out fine. They seemed heavy duty and the cover is a nice touch on it. So far I have had no issues with them and would recommend

Used as distribution block in RV. Well built and easy to install. Backing plate is solid and mounted well. Good product.

This will work great as a 12v Bus Bar.As described and will purchase again.
