Abstract
Abstract A ground level transformer unit including a transformer and a pallet-pad, the pad being formed from a lightweight material and having on one side supporting surfaces of sufficient strength to form a pad mount base for the transformer and a surface for transporting the transformer unit by a fork lift truck and on the other side a number of latching points for accommodating a number of different size transformers, and a tamper proof ridge positioned to correspond to the dimensions of the various size transformers. The pad is permanently attached to the transformer for installation on site. The transformer units can be stacked for storage and shipped as a unit.
