in and out is the same, considering you can use the terminals to take in wire, or put out wire
so because something has 2 1/0 inputs means i cant use one of them to put out wire? hmm... i didnt know that...
also if you wanna get technical, the battery terminal above is considered a distribution block then, what if someone has the 1/0 taking in 1/0 from a big three then using the 4 gauge for a 4f run to the back? therefor it is acting as a distribution block because it is distributing the power throughout
