Electrical Maintenance Technician Module

The Electrical Maintenance Technician Certification requires the prerequisite completion of the Core Knowledge and Skills Certification. Completion of the sections below awards you with the Electrical Maintenance Technician Certification. Some sections are eligible for a National Coalition of Certification Centers (NC3) Certification.

 

• Enclosures and Conduit Systems
  • This section provides practical training in the installation and management of electrical enclosures and conduit systems within an industrial setting. Students will learn to work with various types of conduits, including metal and non-metallic flexible conduits, as well as electrical metallic tubing (EMT) and rigid metal conduit (RMC). The course emphasizes hands-on experience in cutting, bending, threading, and connecting these conduits, as well as safely feeding conductors through them.

 

• Conductor Types and Sizing
  • This section provides students with practical skills in electrical power distribution systems within industrial settings. Students will learn to install, wire, and maintain various components of power distribution networks, distribution panels, conduits, conductors, and downstream distribution panels. The course emphasizes compliance with the National Electrical Code (NEC) and safety standards, preparing students to manage both single-phase and three-phase power systems.

 

• Electrical Wiring
  • This course offers students practical training in electrical wiring for industrial maintenance, focusing on the installation and wiring of electrical equipment in compliance with the National Electrical Code (NEC). Through hands-on job sheets, students will learn to install, wire, and test various electrical components, including motor control circuits, contactors, transformers, and safety switches, within simulated industrial environments. The course emphasizes the importance of safety procedures and accurate wiring techniques, preparing students for careers in industrial maintenance and electrical installation.

 

• Overcurrent Protection Device Types and Sizing
  • This section focuses on the principles of industrial maintenance related to DC motor drives. Students will engage in practical work orders, including the installation of a DC motor drive, while adhering to safety protocols such as lockout/tagout procedures. The course also emphasizes the importance of using the correct tools and understanding the relevant electrical concepts, as aligned with the NEC.

 

• Motor Starters and Drives
  • This section provides practical instruction in the setup and operation of AC motor drives. Students will learn to install, program, and troubleshoot AC motor drives, replacing manual starters in three-phase induction motors with these more advanced control systems. The course emphasizes hands-on experience through work orders that cover topics such as configuring drive parameters, implementing safety procedures like lockout/tagout, and understanding the interaction between AC drives and motor performance.

 

• Basic Controls
  • This section provides foundational knowledge and practical skills in basic electrical control systems used in industrial maintenance. Students will learn to identify, install, and troubleshoot various motor control devices, including push buttons, relays, contactors, and motor starters. The curriculum covers key concepts such as control circuit layout, lockout/tagout procedures, and the operation of control panels and motor circuits. Through hands-on exercises and job sheets, students will gain the technical expertise required to safely and effectively manage electrical control systems in industry settings.

 

• Sensors
  • This section provides an introduction to the principles of sensors in industrial maintenance, focusing on the detection and control of various materials. Students will learn about different types of sensors, including photoelectric, capacitive, inductive, and proximity sensors, and their roles in detecting the presence, position, and properties of objects in automated systems. The course emphasizes hands-on experience, allowing students to set up, calibrate, and troubleshoot sensor systems in simulated industrial environments. This training equips students with the skills necessary to work with sensor technologies in manufacturing and process control industries. This section is eligible for a National Coalition of Certification Centers (NC3) Certification.

 

• Troubleshooting
  • This section equips students with essential troubleshooting skills for industrial electrical control systems. Focusing on practical methods for diagnosing and resolving issues, students will learn to troubleshoot a variety of systems, including basic electrical circuits, motor control circuits, PLC circuits, and AC/DC drive circuits. The curriculum emphasizes hands-on experience through exercises that cover techniques like using voltmeters and ohmmeters, as well as addressing more complex problems involving PLCs and motor drives.
