In my lovely brand new theater. I have discovered that when they wired the stage pin sockets into the raceways they paid no attention to which way is up. So sometimes the you plug in with the double pin end up and sometimes it's down. There is a fourth spot for the screw that holds the socket in place, which makes it really difficult to see which way the plug is oriented without leaning down and getting your face right in it. So Every plug you have to guess which way to plug it in and I'm always guessing wrong. I just sent a message to the theater consultant to find out if this is a mistake that was covered in the specs for the project or if I just have to live with it.
