This session lays the groundwork for understanding the National Electrical Code (NEC). We will explore the structure and layout of the NEC, define key terms that are used throughout the code, and review fundamental electrical theory. A solid grasp of these basics is crucial for interpreting and applying the more complex code provisions you'll encounter in later sessions and on the exam.
Branch circuits are the final leg of the electrical system, delivering power directly to outlets and devices. This session focuses on the proper sizing, protection, and installation of these critical components. We will cover conductor ampacity, overcurrent protection device ratings, and the specific requirements for different types of branch circuits as outlined in the NEC.
The NEC provides for a wide variety of wiring methods and materials, each with its own set of rules and applications. This session will guide you through the common wiring methods, from non-metallic sheathed cable to rigid metal conduit. We will discuss the advantages and limitations of each, and the NEC requirements for their proper installation in various environments.
This session covers the vast array of electrical equipment and devices used in residential, commercial, and industrial settings. We will examine the installation and use of everything from simple receptacles and switches to complex panelboards and switchgear. Understanding the specific NEC rules for each type of equipment is essential for a safe and compliant installation.
The service and feeders form the backbone of the electrical system, bringing power from the utility to the branch circuits. This session delves into the critical tasks of sizing service and feeder conductors, as well as selecting and coordinating overcurrent protection. We will also cover the essential requirements for grounding and bonding to ensure system safety.
Motors and generators present unique challenges due to their inductive loads and potential for inrush currents. This session focuses on the specific NEC requirements for these powerful machines. We will cover conductor sizing, overload protection, disconnecting means, and the various control circuits used to operate motors and generators safely and efficiently.
Certain locations and types of equipment require special attention due to increased risks of fire, explosion, or electrical shock. This session explores the unique NEC rules for special occupancies such as hazardous locations, health care facilities, and commercial garages. We will also cover special equipment like swimming pools, hot tubs, and electric vehicle charging stations.
The electrical industry is rapidly evolving with the growth of renewable energy and low-voltage systems. This session introduces the NEC requirements for solar photovoltaic (PV) and wind power systems, including interconnection and safety standards. We will also touch on low-voltage systems, such as those used for lighting, communications, and security.
The Journeyman Electrician exam features a significant number of calculation-based questions. This final session is dedicated to mastering the most common and challenging calculations you'll face. We will work through examples of load calculations, voltage drop, conduit fill, and motor calculations, and provide strategies for tackling these problems efficiently and accurately on exam day.
