Course Details

This training program helps trainees to learn how to fix electrical problems plain and simple. The Electrical Troubleshooting and Repair course covers use of schematic diagrams, determining sequence of operation, use of building diagrams and single line diagrams. With this training program trainees will learn troubleshooting practices on DC and AC motors, to identify unmarked leads on three phase delta and Y-connected motors. This training program educates trainees about troubleshooting in lighting systems and control devices. Instead of this, trainees will learn troubleshooting steps, electrical two and three terminal capacitors, general operating sequences of a HVAC system and troubleshooting tips related to typical component failures. The prerequisites for this course are knowledge of basic air conditioner components and air conditioner sequence of operation. The training program is beneficial for both fresher and intermediate professionals to enhance their skills.
