    Copeland Compressor Wiring ?

    Could someone give me acess to an internal wiring diagram on a Copeland Compressor Model # LAHA-0310-TAC800/ 208-230V 3 phase. My question is trying to see how the Internal Protectors and Overload are wired in series internally in the compressor via the Load Voltage terminals at Compressors. Access to or a diagram drawn would be appreciated.

    Leatherneck, a TAC has an external overload located in the terminal box. There are no internal overloads. Look at Rockets diagram. The center of the motor windings come up to the terminal cluster from inside the compressor and then the external portion of the cluster goes to the overload. When the overload is closed the motor circuit is complete, when the overload is open the motor circuit is open. The overload has three sets of contacts, one for each winding. When one set of contacts open they will all three open.
