h a p t e r 1  \nDrawing Electrical Diagrams  \nIn this chapter, we will learn the following to World Class standards:  \n􀂃 Training Designers to Draw Electrical Diagrams  \n􀂃 Creating Electrical Symbols for an Electrical Diagram  \n􀂃 Creating a Terminal Block Symbol  \n􀂃 Creating a Ground Block Symbol  \n􀂃 Drawing the Electrical Schematic using Blocks  \n􀂃 Creating an Electronic Symbol Library  \nTraining Designers to Draw Electrical Diagrams  \nWhen training an individual to design products that utilize electricity to function, we need to start with the simplest of products and add complexity as we continue in our experience. There are several reasons to progress in this manner. One, the use of electricity in a product introduces a degree of danger that the designer did not see in developing mechanical assemblies. While drilling holes and shearing metal can result in bodily injury, the danger was visible. When working with electricity, the flow of electrons is invisible to the eye and an inexperienced Designer or Engineer can inadvertently touch a live circuit, which results in an electrical shock. Therefore, we need to include an additional level of safety in our training and designs.  \nOne of the simplest electrical products to construct is designing an on-off switch assembly. The project on these units will include drawing an electrical diagram, creating multiple purchase part drawings, making fabrication drawings, creating graphics and building an assembly drawing. All of these tasks are simple to achieve and yet deserve attention to construct a workable product.  \nThe first step is to draw the electrical diagram. We will learn how to make a handful of electrical symbols, then draw a simple wiring diagram and lastly build a Computer Aided Design (CAD) electrical symbols library.  \nCreating Electrical Symbols for an Electrical Diagram  \nThe key device in our electrical assembly is the toggle switch to turn on our device. You can use a toggle switch like the one shown in figure 1.1 or you can substitute the device with an equivalent part that can switch the same amount of electricity. Some designers will pick a switch actuator or human interface with a lower profile like a pushbutton. Others will concentrate on choosing a more decorate toggle or one that is colorful. Whatever the feel the person gets from using the device, the actuator will not affect the overall action resulting from turning the switch on or off.  \nIn our assembly, we are switching the following electrical parameters.  \nAction: On – Off  \nActuator: Maintain Toggle  \nNominal voltage: 125 volts AC  \nCurrent: 10 amps inductive load  \nPoles: Single  \nFigure 1.1 – Shape of the Socket  \nWe went out on the Internet to find a switch that will meet our parameters and found a device made by Eaton Corporation. With this switch, we can choose three different ways to attach wire to the device. One is by screw terminal, the other is by soldering and the last is by spade terminal. The switches come in different circuit configurations, such as On – Off– On, On – Off and On – On. We can pick a maintain action where the toggle stays in the position set or a momentary action where the toggle stays in a certain position and we close the circuit for a brief time.  \nMomentary switches are like the buttons on a keyboard where a computer user sends a short signal representing a letter or number to the computer. The maintain switch is like the light switch on the wall where the on position keeps the ceiling light on. Figure 1.2 shows the switch selected.  \nFigure 1.2 – Selecting the Toggle Switch from the Eaton Online Switch Catalog 1  \nBefore making a schematic of the simple circuit, we need to draw the electrical symbol for a switch and store the symbol in our library for future use. Set the grid by right clicking on the Grid on the Status bar at the bottom of the graphical display and the Drafting Settings window will appear as shown in Figure 1.3. Set the Grid X and Y spacing to 0.25","cbCaiog9JiJrzjOF","https://ap.wps.com/l/cbCaiog9JiJrzjOF","pdf",576340,12,"English","# Chapter 1 - Drawing Electrical Diagrams\n## Training Designers to Draw Electrical Diagrams\n## Creating Electrical Symbols for an Electrical Diagram\n## Creating a Terminal Block Symbol\n## Creating a Ground Block Symbol\n## Drawing the Electrical Schematic using Blocks\n## Creating an Electronic Symbol Library","[{\"question\":\"Why does the chapter stress additional training and safety for electrical diagram work?\",\"answer\":\"Because electrical systems involve invisible electron flow, an inexperienced designer or engineer can accidentally touch a live circuit, leading to electric shock.\"},{\"question\":\"What is used as the simplest example electrical product in the chapter?\",\"answer\":\"An on-off switch assembly, which requires drawing an electrical diagram, creating purchase part drawings, making fabrication drawings, creating graphics, and building an assembly drawing.\"},{\"question\":\"What parameters are specified for the toggle switch example?\",\"answer\":\"On–Off action, maintain toggle actuator, nominal voltage of 125 volts AC, current of 10 amps inductive load, and single pole configuration.\"}]","Chapter 1 - Drawing Electrical Diagrams - World Class Standards | PDF"]
