ABSTRACT:
A connecting apparatus for constituting a Y-connection of three phase windings of a three phase induction motor or supplying three phase power to the three phase windings includes a first connector and a second connector. The first connector has three terminals respectively extending from the three phase windings. The second connector has a Y-connection plug, which is coupled to the first connector and constitutes a Y-connection of the three terminals. The second connector also has slots for guiding a plug for supplying three phase power to the three terminals of the first connector. Accordingly, it is not required to separate the second connector from the first connector for supplying three phase power to the three phase windings of the induction motor.
