What’s Wiring Diagram

A wiring diagram is a kind of schematic which uses abstract pictorial symbols to demonstrate all the interconnections of components in the system. Wiring diagrams comprise a pair of things: symbols that represent the constituents in the circuit, and lines that represent the connections with shod and non-shod. Therefore, from wiring diagrams, you already know the relative location of the constituents and the way they are connected. It’s a language engineers need to learn once they work with electronics projects.

Wiring Diagram VS. Schematics

It’s easy to get confused about wiring diagrams and schematics. Wiring diagrams mainly shows the physical position of components and connections within the built circuit, and not necessarily in logic order. It emphasizes about the layout of the wires. Schematics emphasize about how circuits work logically. It reduces integrated circuits into sub-components to produce the system’s functional logics better to understand . It’s best for learning the complete operation of the system.

How to Read Wiring Diagram

To read a wiring diagram, first you must know what fundamental elements are included in the wiring diagram, and which pictorial symbols are utilized to represent them. The common elements in the wiring diagram are ground, energy, wire and connection, output devices, switches, resistors, logic gate, lights, etc. A list of electrical symbols and descriptions are available for the “electrical symbol” page.

Line Junction

A line represents a wire. Wires are widely-used to connect the components together. All points down the wire are identical and connected. Wires on some places must cross each other, but that will not imply that they can connect. A black dot is employed to suggest the injunction of two lines. Main lines are represented by L1, L2, and so on. Usually different colors are used to distinguish the wires. There should be a legend for the wiring diagram to share with you what each color means.

Types of Connection

Usually circuits exceeding two components have two basic types of connections: series and parallel. A series circuit is a circuit through which components are connected along a single path, hence the current flows through one element of reach the next one. In a series circuit, voltages accumulate for many components connected inside circuit, and currents are the same through all components. In a parallel circuit, each device is directly connected to the power source, so each device receives the identical voltage. The current in a very parallel circuit flows along each parallel branch and re-combines once the branches meet again.

Tips to Draw Good-looking Wiring Diagrams

A good wiring diagram needs to be technically correct and clear to see. Take care of every detail. For example, the diagram should show the best direction from the negative and positive terminals of each one component.

Use the right symbols. Learn the meanings from the basic circuit symbols and choose the best ones to work with. Some in the symbols have really close look. You need to have the opportunity to see the differences before applying them.

Draw connecting wires as straight lines. Use a dot to point line junction, or use line jumps to suggest cross lines which are not connected.
Label components for example resistors and capacitors making use of their values. Make sure the text placement looks clean.

In general it’s essential to set the positive (+) supply towards the top, as well as the negative (-) supply in the bottom, as well as the logical flow from left to right.

Try to set up the placement reducing wire crossings.
