It is because the properly determined size of load center and panel boards will carry and handle the current as well as the future load (if any) safely and smoothly. Planning is the first and key priority for all electrical wiring projects and a proper estimation and analysis based on accurate calculation is must while designing and installation of a distribution system in residential or commercial applications. An antenna is a straight line with three small lines branching off at its end, much like a real antenna.Sizing Load Center, Panelboards, Distribution Board & Consumer Unit According to NEC and IEC? A resistor will be represented with a series of squiggles symbolizing the restriction of current flow. For example, a switch will be a break in the line with a line at an angle to the wire, much like a light switch you can flip on and off. Most symbols used on a wiring diagram look like abstract versions of the real objects they represent. Select Show Dimensions to show the length of your wires or size of your component.Ĭlick here to read SmartDraw's complete tutorial on how to draw circuit diagrams and other electrical diagrams. You can also change the size and shape of your line hops.
You'll be able to search for additional symbols and open any relevant libraries.Ĭlick on Set Line Hops in the SmartPanel to show or hide line hops at crossover points. If you need additional symbols, click the arrow next to the visible library to bring up a drop down menu and select More. Once connected, it will remain connected even if you move the wire. Drag a symbol onto the line and it will insert itself and snap into place. If you right click on a line, you can change the line's color or thickness and add or remove arrowheads as necessary.
To draw a wire, simply click on the Draw Lines option on the left hand side of the drawing area. Special control handles around each symbol allow you to quickly resize or rotate them as necessary. Customize hundreds of electrical symbols and quickly drop them into your wiring diagram. SmartDraw comes with pre-made wiring diagram templates.
