RSES announce the launch of its updated Electricity for the HVACR Technician eLearning course on the HVACR Learning Network powered by ESCO + RSES.

This is an interactive online course that provides an introduction to the concepts of electricity and magnetism, a description of basic electrical devices that use these concepts, the concepts of alternating current and related devices, and a basic explanation of electrical schematics.

12 Course modules 

The course is broken out into the following 12 modules:

  • Terminology and Units of Measurement: Covers the “building blocks” of matter and understands the relationship between atomic structure and electricity;
  • Electronics - History and Concepts: Provides an introduction to the basics of electronics, and will help users understand the difference between the terms “electronics” and “electric;”
  • Series Circuits, Parallel Circuits, and Power: Explains a series in a circuit and states the three rules that govern the behavior of a series circuit;
  • Magnetism and Transformers: Focuses on the concept of magnetism, the various types of magnets in use currently, and their characteristics;
  • Magnetic Attraction, Repulsion, and Shielding: Defines magnetic lines of force, explains magnetic fields, and defines magnetic flux;
  • Transformers: Explains the purpose of a transformer, describe the components of a transformer, list the common defects user may encounter when working with transformers, and explain how the power-handling capacity of a transformer is measured;
  • Relays, Contactors, and Starters: Discusses the workings of relays, contactors, and starters;
  • Fundamentals of Alternating Current: Studies the nature and composition of alternating current. You will be able to explain alternating current and explain sine waves;
  • Alternating Current: Reactance, Impedance & Power Factor: Teaches how to calculate the resistance offered by capacitors and inductors;
  • Circuit Protection Devices: Fuses: Discusses the conditions under which protection is needed, and describes the different types of fuses;
  • Circuit Protection Devices: Circuit Breakers & Overload Protection: Covers the main components of a circuit breaker, explains the basic function of a circuit breaker; and
  • Understanding Electrical Schematics: Describes how wiring diagrams can be read, identify different types of wiring diagrams used in the HVACR industry, and name the five basic components of any schematic.

certificate of completion

Each module, which may be purchased individually or together as one bundled course, includes an end-of-module certificate upon the successful completion of an exam. The course is approved for 36 NATE CEHs or 3.6 CEUs. All modules together provide approximately 30–40 hours of electrical training.

This online course and the individual modules closely resemble the RSES Electricity for HVACR Technicians manual as well as various lessons covered throughout the Electricity Unit manuals, however, the eLearning option further supplements and stresses the safety issues related to the HVACR industry.
