Install this first to avoid any arcing (turn to off position). Works perfectly! Both ends came pre-treaded at 5/16 size bolt. I used 3/8 bolt because it came on the lithium battery threads, laid it flat against terminal and tighten it down. On the 5/16 other end, I just made two lug rings to fit exact and tighten it down with room to spare if I needed to add another positive wire.

Good quality and it shuts the battery off. However, the lug bolts do not fit an Epoch battery terminal lug. Had to use a different bolt on the battery to connect it. Had to drill out the power feed lug on the trailer to fit the threaded lug on the shut off switch. Was not "plug and play," but got it to work on my rv.
