Abstract
A terminal box assembly for use in a dynamoelectric machine adapted to be energized from an electrical power source and including a plurality of windings and each winding terminating in a corresponding lead wire. The lead wires are connectable to each other and to an electrical power source in at least two different configurations for operating the motor from two different voltages. The terminal box assembly includes a plurality of terminations for connection to each of the lead wires and a terminal block having a plurality of apertures for receiving the terminations. A plug device is provided for coupling with the terminal block in at least two different orientations for interconnecting the lead wires of the motor windings. A base member is releasably coupled to the terminal block and includes a latch integral with the base for releasably coupling the terminal block and base member to the dynamoelectric machine. The terminal block also includes apparatus for connecting the electric power source to at least some of the terminations for energizing the windings of the dynamoelectric machine.
