Back To Basics

Welcome to Module 3, Fundamentals of Electrical Distribution.

If you have successfully completed Module 2, Fundamentals of Electricity, you are prepared to begin learning about electrical distribution systems and the associated equipment. If you have not completed Module 2, Fundamentals of Electricity, we recommend that you complete that module before you begin this one. This module will present a number of different topics, phrases and terms common to the world of electrical distribution. You will be introduced to information that will be used in later modules.

Like the other modules in this series, this one presents small, manageable sections of new material followed by a series of questions about that material. Study the material carefully then answer the questions without referring back to what you’ve just read. You are the best judge of how well you grasp the material. Review the material as often as you think necessary. The most important thing is establishing a solid foundation to build on as you move from topic to topic and module to module.
