Seminar Overview

In the field of equipment maintenance, installation or modification, the ability to read and understand electrical ladder drawings, schematics and diagrams is an absolute must. Several types of drawings and diagrams will be examined during this electrical 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.  Electrical Ladder Drawings, Schematics and Diagrams 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. Download the full brochure.
