This is an example of electrical wiring diagram about the control transformer ground system. The control transformer is properly grounded to the L2 side of the circuit. When the circuit works, the entire circuit on the left side of the coil M is an ungrounded circuit. So what is the wiring diagram?
A wiring diagram is a graphical depiction of the components and cables that comprise an electrical connection. Wiring diagrams are widely used in circuit design and other electronic device tasks. The layout promotes communication between electrical engineers who design and install electrical circuits. A wiring diagram is very important in vehicle maintenance and house construction projects.
