all square d's come with directions, its a little folder up piece of paper inside the housing, and i think the sticker inside the cap has it too..either way, that switch has two curcuits, and you only use one for each comp. theres a plastic divider in the middle of the four terminals, you only use two terminals on each side, you dont jump across it. then just hook it up like any other p/s.
