It clearly shows the components with its proper electrical connection. This is a wiring diagram of a three phase wiring installation in a home. they are mostly used for wiring installation in home and industries.Įxample: Three Phase Electrical Wiring Installation Diagram It really helps in showing the interconnections in different equipment such as electrical panel and distribution boxes etc. Wiring diagram shows a pictorial view of the components such that it resembles its electrical connection, arrangement and position in real circuit. Vertical and horizontal lines are used to represent wires and each line represents a single wire that connects between electrical components. The wiring diagram is used for the representation of electrical components in their approximate physical location using their specific symbols and their interconnections using lines. Hence, only one contactor may be operational at a time. The following schematic wiring connection diagram shows a three-phase motor is controlled by two power supply where both contactors are electrically interlocked. Schematic diagrams are crucial in designing, analyzing, and repairing electrical and electronic systems, providing a clear and abstracted view of how a circuit operates without the need for a detailed physical representation. Symbols and actual components in a schematic diagram represent various elements like circuit breakers, contactors, resistors, capacitors, transistors, wires, and connections, allowing for a concise and standardized way to convey circuit information. Unlike a physical layout diagram, a schematic focuses on the logical arrangement and functioning of the components within a circuit, making it a valuable tool for engineers, technicians, and electricians to understand and troubleshoot complex systems.
