Today i am writing about shunt trip breaker wiring diagram which related with safety and protection of electricity.
As you know that Safety is important in electricity works. The basic operation of the stopstart circuit is to provide a means of remotely controlling a motor operated load from a panel that only contains the low voltage control circuitry. An example of a wiring diagram for a motor controller is shown in Figure 1.
Three-phase electric power abbreviated 3φ is a common type of alternating current used in electricity generation transmission and distribution. 3 phase three. A potential problem with this system as it is designed is that the human operator loses control of the motor in the event of an open wiring failure in either pushbutton switch circuit.
