I used this as a junction point on a 1 gauge wire. I added an 8 gauge wire to one side, and the cover would not seat. I had to bend and maneuver the ring terminals to make the cover catch. For the price of the items, if used without any secondary wires attached and interior use only, this is an unbeatable deal.
