Using in my RV for the Negative Buss
I'm using the black one in my RV for my 12 volt negative buss. I have the blue sea MRBF fuse buss on the positive side. I've run it all season with no problems. It was easy to install and it cleaned up my battery compartment which was a mess of wires all bolted on the battery posts. I have 1/0 cable running to a Victron 300A current shunt and then to the batteries from this. On the buss bar I have the solar, rv coach panel, and the generator start circuit on it. All current flows through the shunt so it can monitor the battery state of charge effectively. I would buy it again.

Cleaned up battery compartment
Installed on my boat instead of having multiple wires on the battery. Cleaned up the process of changing my battery nicely. The are heavy duty and have a waterproof cover. Installed easy and have been working fine for a couple of months now

Nice solid bar for the current
Solid, looks good, and the cover isn't flimsy or cheap looking. The covers for the openings on the sides can be removed and put back if something changes. I did an under hood battery delete when I got a lifepo4 for the back and this is solid enough for the current.
