Understanding some of the fundamental concepts of electrical circuits is vital to being able to operate and troubleshoot electrical systems. This course covers some basic electrical terminology, the sources of electricity, circuit overcurrent protection, and methods for measuring electricity. Electric current is driven by an electric potential difference, or voltage. Voltage sources include generators, batteries, and photovoltaic sources. Conductors are materials which allow the free flow of electricity and connect all other components in an electrical circuit. Insulators are materials which block the flow of electricity. The flow of electricity within a circuit needs to be properly contained. There is a need for protection from the dangers of overcurrent conditions in circuits. This protection is provided by fuses and circuit breakers. Electrical systems should also be grounded and bonded. A multimeter is a device that can be used to measure voltage, current, and resistance. Permanently-mounted power meters measure the amount of power entering a building and how it is consumed throughout the building.

Electrical power is essential to the operation of a modern building. This power is generated by a utility company and is delivered to buildings through transmission lines. Electromagnetic induction of alternating current is the principle which enables generators to create electricity, transformers to change its voltage for transmission, and motors to convert electricity back to mechanical energy. At the building, electrical power is manipulated, distributed, and controlled in various ways before being actually “consumed” at an end load. Overcurrent in electric circuits is prevented by fuses and circuit breakers. GFCIs and AFCIs use solid state circuitry to provide an additional layer of circuit protection. Different types of lighting require different types of controls. Triacs are used in dimmers for incandescent lights, ballasts are required for fluorescent lamps, and LED drivers are used to power LED lighting. This module covers the steps and components that are typically used to control the distribution and control of electrical power throughout a building.

Electrical power is the lifeblood of a modern building. It provides light, heating, cooling, and power for many electrical devices. Although there is great value in electrical power, it has shortcomings. If it is not handled properly, it represents a significant direct health hazard in the form of electrocution. Additionally, improper installation of wiring or electrical equipment has been the source of countless fires. For these reasons, several organizations have set up guidelines and regulations regarding the installation and use of electrical equipment. One of the most significant set of regulations is the NEC, or National Electric Code. This set of guidelines was first developed by the National Fire Protection Association (NFPA) in 1897, and has been updated every three years since then. Code-enforcement agencies may choose to enforce the current NEC codes, older editions of it, or alternate versions that incorporate local modifications. Designers and electricians should verify the codes and editions in force and consult authorities having jurisdiction (AHJ) regarding their interpretations of ambiguous or conflicting requirements. This module describes how power is delivered to and distributed throughout a building. It also covers some of the major code issues governing this process.
