Understanding and Using Electrical Wiring Diagrams
The purpose of this course is to provide an overview of drafting and drawings used in the electrical industry. The electrical drawing’s purpose is to transfer electrical information or requirements to one or several users so that productive work may be performed. This work may consist of such actions as estimating, planning, manufacturing, construction, commissioning, maintenance and troubleshooting.
This course is intended for use by those new to using electrical drawings or those wishing to refresh their knowledge of the associated function and components that make up the electrical drawing system.
There are several types of drawings depicting electrical circuits which are outlined in this course. The types of diagrams that will be reviewed include the:
Operating Diagram
Schematic or One Line Diagram
Electrical Arrangement
Elementary Wiring Diagram
A.C. Elementary Wiring Diagram
D.C. Elementary Wiring Diagram
Connection Wiring Diagram
Block Diagram
Successfully performing electrical work requires the ability to read and interpret many different types of drawings and diagrams. Understanding circuit symbols and components is another one of the basic building blocks needed to become an electrician. If an electrician misinterprets a drawing or diagram when wiring a house, devices could be incorrectly installed or even missed altogether. Knowing how to properly take information from an electrical drawing or diagram and apply it to the real world is essential for electricians.
This course is intended for use by those new to using electrical drawings or those wishing to refresh their knowledge of the associated function and components that make up the electrical drawing system.
It will also serve as an excellent source of reference for students studying electrical engineering or technology as well as providing a review for those working in the electrical industry.
