## Description

desertcart.com: 600A Bus Bar 12V Power Distribution Block with 3/8" (M10) 4-Posts Heavy Duty Terminals Block with Cover for Automotive, Marine, Battery System (Black) : Electronics

Review: Well made product - Well made , at a great price. Exactly what I need to take care of my problem.
Review: 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.
