NCTS Electrical With Troubleshooting Outline
Course Description:
Prerequisites: Use of a Digital Voltmeter, the basics of electrical circuits, Ohms law, and schematic symbols.
The Fundamentals of Electrical Troubleshooting class gives you an understanding of how to read and interpret or navigate Schematic Diagram’s and use this interpretation to troubleshoot circuits. All trades have a certain language (Relay Logic) to enable rapid and efficient transfer of information for troubleshooting.
This class covers these relay logic: symbols, drawings, diagrams, words, phrases, and abbreviations needed to troubleshoot. The information covered is called control logic, using line diagrams. Line diagrams show the logic of an electrical circuit. The student will identify this with manual, automatic, or magnetic control of circuitry components. VFD operation and functions will be demonstrated in class. Multi-page ladder line diagrams will be used in class to have the student fully understand the navigation process. Testing Single Phase and three-phase motor types will also be included.
Duration: 40 Hours
