Course Description

This course is designed to prepare someone in the Mechanical Maintenance Craft to be able to safely work with electrical equipment and to troubleshoot electrical control devices, motors, basic switching, SAC circuits, DC circuits and effectively use a Multi meter. Voltage, Current, Resistance, Power and their formulas are also covered.

Topical Outline

• Discuss the relationship of Voltage, Current, Resistance and Power.
• Develop an understanding of Ohm’s Law and the Power circle.
• Identify fundamental electrical devices and their symbols.
• AC circuits, switches, resistors, conductors, capacitors, coils
• Analog and Digital Multi Meters, Solenoid type voltage meters, Fuzzy Sticks
• Measure AC current with clamp-on meters
• Test AC circuits for correct polarity and grounding
• Compare resistance measured using an Ohmmeter to listed values on Resistors and Devices
• Troubleshoot control Circuits using Ladder Diagrams to identify open fuses, defective switches, relays, etc.
• Describe the characteristics of Capacitance and Inductance
• Compare resistance measured using an Ohmmeter to listed values on Resistors and Devices
• Troubleshoot control Circuits using Ladder Diagrams to identify open fuses, defective switches, relays, etc.
