ABSTRACT:
One of a plurality of taps of at least one transformer is selected by choosing a predetermined plug to mate with a predetermined jack. The connection arrangement between each transformer and a corresponding jack is such that each pin of a respective jack is operatively connected to a predetermined transformer tap of the corresponding transformer whereby the corresponding taps of each of the transformers are connected to different corresponding pins for each of the corresponding jacks. Further, the starting tap of each transformer is operatively connected to the same corresponding pin of the jack corresponding to the transformer. A plurality of plugs, the number of plugs corresponding to one less than the number of pins of the jacks, is included whereby each plug has a plurality of mating pins corresponding to the pins of the jack. Each mating pin of each plug which corresponds to the pin of the starting tap is operatively connected to a first supply terminal. Each plug has a different mating pin from all of the other plugs operatively connected to a second supply terminal.
