Abstract
A pad-mounted transformer enclosure may have a wiring compartment utilizing multiple hinge points on each side panel with an additional set of hinges located at the back of the compartment area to allow the doors to be opened as normal or to allow the sides to be also opened, allowing the wiring compartment to be totally exposed on all three sides. The tank of the transformer enclosure may have a cover secured in a manner that allows the cover to be removed with simple hand tools while preventing unauthorized removal thereof, that increases tank top structural rigidity, and that does not trap water on the tank cover.
