• define electric shock, understand the process of grounding, and describe the purpose and function of a Ground Fault Circuit Interrupter (GFCI)
• compare voltage surge with transient voltage and explain overvoltage installation categories
• identify common fire safety hazards, describe fire extinguisher classification, and learn about the dangers of confined spaces
• calculate the appropriate over-current protection for control transformers and install grounding as it relates to control transformers
• explain how control transformers are sized and identify concerns related to undersized control transformers
• identify common control transformer applications and identify potential, current, and variable transformers
• understand parallel transformers and identify two methods of creating a satisfactory parallel connection between two transformers with unequal impedances
• terminate T-connection, a zigzag connection, a Scott connection, and introduced to 2-phase power systems
• identify safety requirements related to the installation of dry-type transformers, less-flammable liquid-insulated (LFLI) transformers, and nonflammable fluid-insulated (NFFI) transformers
• identify factors related to satisfying transformer overcurrent protection requirements and safety requirements related to the installation of transformers rated at over 600 V, nominal. Identify safety requirements related to the installation of transformers rated at 600 V, nominal, or less
• identify common safety guidelines to be followed when performing maintenance or troubleshooting
• identify common types of insulation testing and describe the requirements for satisfactory testing results
• identify additional transformer tests and their functions
• apply safety codes and standards to your electrical installation and recognize electrical work hazards
