Motor control wiring diagram. Here i showed the forward reverse wiring diagram. In the diagram i connect the incoming three phase supply l1 l2 l3 to the mccb circuit breaker molded case circuit breaker. Basic wiring for motor control technical data.

The basic control circuits include two wire three wire controls manual automatic sequential control stopstart forward reverse and jogging circuits. If there are no convenient motor control circuit diagrams available for illustration you may want to ask a student to draw an across the line starter circuit on the whiteboard for everyone to see. Two wire control as seen in configuration 1 consists of a control device containing one set of contacts used to facilitate the on an off operation of a pilot device.

For example the start pushbutton we mentioned earlier has wires run to the device that contains the set of con tacts m in figure 14 and to contact points 2 and 3 in figure 16. Motor 3ct to 120 v separate control ot is a switch that opens when an overtemperature condition exists type mfo. Ac motor control circuits ac electric circuits.
