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
