Abstract
A tank for a load tap changer includes opposing front and rear walls, opposing side walls, and a bottom wall joined to define a box-like structure. A door structure is removably coupled to one of the walls. An oil catch tray is coupled to the tank and is movable between a retracted, storage position generally adjacent to the bottom of the tank, and an operative position extending outwardly from the one wall to which the door structure is coupled and generally under a portion of the door structure. In the operative position, the oil catch tray is constructed and arranged to collect oil that drips from the door structure and the one wall when the door structure is removed from the one wall.
