In this Power Distribution course, you will discover how electricity goes from the generation station to residential, industrial and commercial sites. This course begins by explaining how the power from the high voltage lines transforms into usable voltage in the home, and where residential ownership of these lines begins. It then continues with what exactly a transformer is in addition to how it works. You will learn about the three different types of transformers: isolation, auto, and buck boost. Finally, you’ll take a look at three-phase power, what it is and why it is used, in addition to the two types: Wye and Delta.

According to the Bureau of Labor Statistics, slips, trips, and falls cause nearly 700 fatalities per year and many more injuries in construction. If you work in a trade, you’re going to encounter slip, trip, and fall hazards from time to time that can cause injuries or even kill you. This course is intended to provide you with the ability to recognize and prevent slip, trip, and fall hazards, and to address the key components of ladder safety.

A brief overview of residential HVAC Psychrometrics as it relates to the HVAC industry. This course is intended to provide a basic understanding of the principles of psychrometrics and various tools needed to make psychrometric calculations and measurements for optimal comfort, including thermometers, anemometers, and psychrometers. The course will identify how to calibrate and use specific tools for HVAC technicians, including a psychrometric chart.

In this course, we’re going to be discussing the different components, configurations, fuel types and cleaning systems of ranges. The course begins with a couple lessons on identifying the various components, covering the control panel, cooking surface, oven, and a few more. Following that, there's a section on the different configurations, including freestanding, slide in and pro style ranges. You’ll learn about the differences between each of them and why you might choose one over the other. In the lessons after that, you’ll learn about all the considerations involved in choosing between gas, electric and induction fuel types. The course concludes with a lesson on oven cleaning systems, where we’ll take a look at the different cleaning methods available for ranges.

Learn how electricians use blueprints, wiring diagrams, and schematics and apply them to real world applications. In this course you'll learn about the parts of a blueprint that an electrician uses, the difference between a wiring diagram and a schematic, and how these schematics and drawings are used on the job.

The world of refrigeration is changing. Ongoing regulation of refrigerants based upon environmental impact is forcing manufacturers to seek out new solutions. In this course we discuss how refrigerants work and why certain past refrigerants were phased out. We will dive into the most common characteristics and differences between past, current, and future refrigerants.

The Refrigeration System Accessories course dives in to the auxiliary mechanisms one may find in a system. Each of these mechanisms augments the performance of the system in some way, from filter dryers to crank case heaters. Explore each component’s function, location, style and application.

This simulation based course walks you through step by step of how to diagnose and repair 13 common refrigerator problems that you may encounter on the job. You will work through various cases of malfunctioning refrigerators. This is a fun, interactive and effective way to learn how to fix a refrigerator.

This is an assessment simulation, where you'll use the steps and skills you've learned and practiced on the Interplay platform to determine the fault and fix each scenario. Use the bottom tool bar to navigate around the environment, inspect components, access tools, and view diagrams. This is designed to mimic a real-world scenario, so there's no step by step guide giving you instructions for how to troubleshoot the scenario.

In this course, we’re going to be overviewing refrigerators. We’ll start off with a lesson where you’ll identify the different components of refrigerators and each of their purposes. After that we’ll take a deeper dive into the different configurations, discussing installation methods, door styles, and types of refrigerators. Finally, we’ll take a look at the operation of refrigerators. You’ll learn about the refrigeration process and how these appliances are able to regulate cold temperatures. Following that lesson, we’ll conclude with a lesson on the various evaporator and compressor setups, looking at the advantages and disadvantages of each.
