Introduction To Reading Of Electrical Drawings and Diagrams

Course Description

This Five-day electrical drawing course is designed to prepare electrical personnel to troubleshoot from electrical drawings at commercial, industrial and institutional installations. Students will begin with one-linesand three-lines, and progress through schematics and relay/ladder logic diagrams. Students are encouraged to bring examples of their own facilities prints to use during practical exercises. Low, medium and high-voltage installations will be reviewed as requested by students.
