About This Course

This course is designed to teach the knowledge necessary to classify and size, cut and thread, and bend and install conduit and conductors.

You will learn the different types and sizes of conduit and how to cut, thread, bend, and install it; to use calculations; and to install conductors.

Lesson 1: Classifying and Sizing Conduit

Conduit is a rugged, protective tube through which wires are pulled. Careful planning and practice will result in a professional-looking electrical system. A conduit wiring system is probably the most challenging of the electrical systems to install.

Although several types of conduit are used in electrical work, only the following types will be discussed in this course: rigid-steel, electrical metallic tubing (EMT), rigid non-metallic (polyvinyl chloride [PVC]), and flexible metallic and nonmetallic conduit.

In this lesson, you will learn some of the different types and sizes of conduit used in electrical work.

1-1 Rigid Steel Conduit
1-2 EMT Conduit
1-3 Rigid Nonmetallic (PVC) Conduit
1-4 Flexible Metallic and Nonmetallic Conduit

Lesson 2: Cutting and Threading Conduit

Although it may seem at first glance to be a simple task, cutting and threading conduit efficiently requires considerable skill. With the instructions that follow and on-the-job experience, you should soon be able to do this well.

You will learn the methods on how to cut and thread conduit.

2-1 Cutting Conduit
2-2 Threading Conduit

Lesson 3: Bending Conduit

One of the tasks you will have as an electrician is to make field bends in conduit. Although conduit bending is thought by many electricians to be difficult, it is fairly simple. It does require some thought, simple math calculations, and a lot of practice.

You will learn how to use calculations and make bends in conduit.

3-1 Methods of Bending Conduit
3-2 Types of Bends
3-3 Types of Benders

Lesson 4: Installing Conduit and Conductors

This lesson discusses the specific requirements for installing conduit and conductors.
You will learn how to install conduit and conductors as per construction prints and the NEC.

4-1 Installing Conduit
4-2 Installing Conductors
