A 2-Day Course to Help You Understand All the Electrical Languages that Run your Facility and Equipment

Workshop Description/Agenda

In the field of equipment maintenance, installation or modification, the ability to read and understand schematics and drawings is an absolute must. Several types of drawings and diagrams will be examined during this course including Block, Pictorial, One-line, Wiring, Terminal, and Schematic. The differences between these drawings will be emphasized and the purpose and flow of each type will be clarified. In order to learn the symbolic language, you must start at the beginning. In doing so, individual component symbols will be presented along with an explanation of their function and purpose in the circuit. In order to make it easier to relate the diagrams to the actual equipment, students will see pictorial examples or photos of the components along with the description. Training will include exercises where students create schematic diagrams based on circuit descriptions, as well as interpreting schematic drawings so that they can provide verbal or written circuit descriptions.

Who should take this course?

This course is designed for anyone who needs to understand electrical drawings and schematics for servicing and troubleshooting facility and industrial electrical systems. Attendees come from a wide variety of industries, skill-levels, company sizes, and backgrounds, so if you're not sure you'll fit in or will benefit from these classes, don't worry - you will - as long as you work with electricity!
