What is a one-line diagram?
This type of electrical diagram would use single lines and symbols to show the path and also the components in an electrical circuit. By using this diagram we could determine the circuit connection and their component, but we won’t be able to determine the actual location of the component by using this diagram. By using a line diagram, we could easily determine the connections and also the components in an electrical system. This diagram is widely used in an industrial power system, in this diagram multiple conductors of power and control circuits are shown as single lines.
What is a wiring diagram and how to interpret it?
The wiring or connection diagram is an electrical diagram that would show the connection of installation or its component device or parts. According to the wiring diagram the electrical inspector can do the electrical wiring in an industry. This diagram would be useful during the wiring and also after the completion of the wiring. The major benefit of a wiring diagram is that it would show almost the proper location of the component in a circuit. These diagrams are used by the equipment manufacturers to install the wires in electrical equipment such as switchboards and panels. We can also determine the interconnection of the electrical component by using this diagram. This diagram would display the electrical equipment in its proper physical location and thus it can be used to check the actual location of the equipment.
