Circuit diagram

A circuit diagram is a connecting of electric and electronic devices or this is an internal diagram of any electric device Exp. Mcb circuit diagram, relay circuit diagram.
Circuit Diagram just shows the simple connection between components or components internal connection.

Loop wiring diagram

Loop wiring is a diagram which shows detailed connection from one point to control system or from field to control system.

Difference between Wiring Diagram and Circuit Diagram

Loop Wiring Diagram Circuit Diagram
Loop wiring diagram gives the layout of wiring.Circuit diagram does not give the layout of wiring.
a loop wiring diagram is always a device-to-device connection.Circuit diagrams can be both devices to devices or internal diagrams of devices like a relay circuit diagrams.
Wiring Diagram shows the actual position of components and also shows the distance between components.Circuit diagram or schematic diagram does not show the position and distance of components.
There mainly two types of wiring diagram are used, one is single line diagram and another is multiline diagram.Circuit diagram or schematic diagram not classified into single line or multiline diagram.
Wiring Diagram is mainly used to know, how connections are actually made.The circuit diagram is used to understand the working and operation of an electrical circuit.
Wiring diagrams are used by technicians who are working on the field.Engineers use the circuit diagram to convey the operation of a circuit to other engineers.
Wiring diagram may not contain all the straight lines for the indication of conductors.There is always straight line is used to represent the conductors.
Generally, the wiring diagram is drawn after the circuit diagram.Circuit diagram or schematic diagram is drawn first to understand the operation then wiring diagram is drawn of that schematic diagram.
