Interesting I`ve always been told the hinges are on the left facing a discon.And thats it`s stronger side. The latches to hold the door closed are on the right. the door if blown open it`s weaker at the left towards the handle so turn on with right hand face away and if blown open the door will hit your forearm aide in head start for the truck.All the breakers or doors I`ve seen have blown open at the door from the handle side where the latches are.All the down stream loads were off when the main was energized thats what puzzled everyone.We had installed a 37.5 kva buck boost to supply an rf dryer but all the disconnects were off and were doulble checked to make sure they were actually off.
