- Discuss transformer installation, grounding, and electrical systems
- AC/DC theory
- Basic AC/DC electrical generation
- DC series parallel circuits
- AC/DC waveforms
- Basic three-phase AC
- Electronic principles and applications
- Current and voltage values
- Calculating voltages and currents for load and windings
- Use of Wye or Delta wiring schemes
- Functions, operation, and characteristics of various types of distribution systems
- Industrial blueprints
- Introduction: extension of basic and intermediate plan reading applied in an industrial setting
- Specifications extension of basic and intermediate specification reading applied in an industrial setting
- Proper transformer, grounding procedures, and electrical systems
- Steps for receiving and preparing transformer for installation
