ABSTRACT:
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention deals with the field of mounting pads used for supporting large pieces of equipment in external environments normally positioned on ground, earth, turf, grass, cement, asphalt or other similar common ambient substrates. Such mounting pads are preferably formed of a plastic material to maintain electrical isolation between the equipment and ground and also to maintain the equipment spaced upwardly from the ground to prevent ambient water from rainfall or minimal flooding from damaging the electrical equipment.
Such mounting pads are most commonly used to support electrical power transformers which are used currently in commonplace applications such as residential areas. Such residential areas currently utilize underground electrical wiring and the mounting pads normally provide a means to allow the electrical power transformer to have access directly to the ground immediately therebelow to pass wires and the like from the transformer to the ground while at the same time maintaining the electrical power transformer out of contact with ground and water and other external deteriorating influences that are commonplace in such ambient environments. Since most residential areas currently being constructed utilize underground electrical wiring such mounting pads are becoming increasingly more common in usage throughout the United States and elsewhere.

SUMMARY OF THE INVENTION
The present invention provides an improved mounting pad apparatus which is designed for the particular purpose of supporting and allowing the moving of an electrical power transformer which is secured thereto. The configuration includes a load supporting deck which extends generally horizontally and is adapted to support and electrical power transformer. The load supporting deck defines a deck access opening therein which facilitates electrical access from the environmental substrate therebelow to such an electrical power transformer positioned on the load supporting deck. Such access is normally electrical wiring and other electrical communication conduits which travel below ground in certain residential and commercial areas and need to be protected as they travel upwardly to electrically communicate with the electrical power transformer. As such, this deck access opening provides this protection and while at the same time providing access. The load su
