Here is a little bit of what i have been working on today. Well first, i wanted to take a few pictures of these terminals with those outrageous 2/0 copper lugs on them. Just to see if they would actually fit. I knew they did but since people been asking i just wanted to clarify. You can use ANY wire that has a ring terminal on it. 5/16" opening on the hole. You can use 2/0, 1/0, 4ga, 8ga (as pictured here)...heck you can wrap a small wire around one of the bolts, oldschool style if you have to haha! Oh, and if you scroll down, there is something you might REALLY like....i know i like it so far
