Purpose of Electrical Conduits

Electrical conduits provide a protective pathway for electrical wiring. They shield wires from physical damage, moisture, and corrosive elements. Conduits also help in organizing and routing wires, making it easier to manage complex wiring systems.

Hand Bending Techniques

Master the art of hand bending conduits with detailed instructions and practical tips. Learn how to measure and mark conduits accurately, use hand benders effectively, and create precise bends. This module will also cover common bending angles and how to achieve them.

Equipment for Hand Bending

Discover the essential tools and equipment needed for hand bending conduits, including hand benders, pipe vises, and measuring tapes. Understand the importance of maintaining your tools and ensuring they are in good working condition for accurate bends.

Module 3: Raceways and Fittings

In this module, you will learn about raceways and fittings. You will become informed on the different types of metal conduit fittings available to electricians and how to store raceways.

Types of Raceways

Raceways are channels designed to hold and protect electrical wires. Common types include rigid metal conduits (RMC), electrical metallic tubing (EMT), and flexible metal conduits (FMC). Each type has its own applications and installation requirements.

Fittings and Connectors

Learn about the various fittings and connectors used to join and secure raceways. These include couplings, elbows, and adapters. Understand the importance of selecting the right fittings for your specific raceway type to ensure a secure and compliant installation.

Storage and Handling of Raceways

Proper storage and handling of raceways are crucial to maintaining their integrity and performance. This module will cover best practices for storing raceways, including keeping them in a dry and protected environment, and handling them carefully to avoid damage.

Module 4: Conductors and Cables

In this module, you will become knowledgeable on conductors and cables. You will be able to identify different equipment used for installing conductors into conduits. This module will also teach you the procedure involved in feeding conductors into conduits.

Types of Conductors and Cables

Conductors are the current-carrying components of electrical wiring systems. Common types include copper and aluminum conductors, each with its own advantages and applications. Cables are assemblies of conductors and insulation, used for various electrical installations.

Installation Equipment

Discover the tools and equipment needed for installing conductors and cables, such as fish tapes, pulling grips, and lubricants. Learn how to use these tools effectively to ensure smooth and efficient installation.

Feeding Conductors into Conduits

Understand the step-by-step process of feeding conductors into conduits, from preparing the conductors to pulling them through the conduit. This module will cover techniques for minimizing friction and avoiding damage to the conductors during installation.
