For example, once the electrical designs are complete, they must be built by an electrician. Therefore, it is your responsibility to effectively communicate your design intentions to the electricians through drawings.

As the piston in your engine moves downward it creates a vacuum which draws in air through the intake end of the carburetor. As the air travels through the venturi, the air’s pressure drops, and fuel is drawn down from the fuel bowl, and then back up through the main jet and emulsion tube. The low pressure air mixes with and atomizes the fuel. This air/fuel mixture continues through the intake valve and into your combustion chamber.

Line diagrams, also called “schematic” or “elementary” diagrams, show the circuits which form the basic operation of the controller. They do not indicate the physical relationships of the various components in the controller. They are an ideal means for troubleshooting a circuit.

You must totally enclose conductors and their connection external to the control panel enclosure in suitable raceways or enclosures. Unless used for flexible connections involving small or infrequent movements, or connections to normally stationary motors, limit switches and other externally mounted devices, fittings used with raceways or multiconductor cables must be liquidtight.

A highly disturbing device (variable speed drive, frequency converter, etc.) will have less radiation in the panel if it is “encapsulated” in a small, electromagnetically sealed, unpainted metal enclosure.

Electrical symbols are used on home electrical wiring plans in order to show the location, control point(s), and type of electrical devices required at those locations. These symbols, which are drawn on top of the floor plan, show lighting outlets, receptacle outlets, special purpose outlets, fan outlets and switches.

Figure 5 below shows a schematic diagram for a PLC based motor control system, similar to the previous motor control example.
