Introduction to "Understanding and Using Electrical Wiring Diagrams"3:11
Learn to read and use electrical wiring diagrams by exploring types, symbols, and standards, enabling effective communication for estimation, planning, manufacturing, construction, commissioning, maintenance, and troubleshooting.

Schematic Diagrams23:39
Explore schematic diagrams as symbol-based road maps of electrical circuits, compare block, schematic, and wiring diagrams, and learn to read and troubleshoot circuits with standard conventions and programmable logic controllers.
Block Diagrams18:07
Explore block diagrams as simple representations of electronic systems, showing interconnections and signal flow from input to output with blocks. They help develop schematics and clarify circuit interactions.
Component Symbols (1 of 2)52:23
Explore how component symbols define circuit diagrams, including resistors, capacitors, inductors, variable resistors and potentiometers, plus diodes, transistors, relays, switches, and vacuum tubes.
Component Symbols (2 of 2)23:52
Explore transformer fundamentals, including air and iron core types, primary and secondary windings, and symbol representations. Examine three-phase delta and wye connections, grounding, and line-to-line versus line-to-neutral voltages.
Logic gates14:05
Explore how logic gates process binary inputs and outputs using truth tables, covering and, or, not, nand, nor, xor, and xnor, with voltage logic levels and solid-state gate operation.
Simple Circuits31:34
Explore reading and drawing simple circuit schematics by learning basic symbols, interconnections, and the relationship between pictorial diagrams and schematic diagrams through flashlight, field strength meter, and power supply examples.
Complex Circuits31:37
Break down complex circuits into simple building blocks and trace signal flow from crystal radio to audio amplifiers, using schematics to troubleshoot at the component level.
Electrical Devices in a Power System26:47
Explore how electrical wiring diagrams, including one-line and three-phase drawings, communicate project objectives, installation guidance, and as-built records using symbols for relays, fuses, breakers, and transformers.

Requirements

A basic understanding of electrical circuits is required including three phase power systems.

Description

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.

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.

Who this course is for:

Electrical Managers, Electrical Engineers, Electrical Technicians/Technologists, Electrical Maintenance Workers, Students enrolled in electrical courses.
