Courses at many technical colleges will cover conduit bending. However, it is an advanced skill, so there may be prerequisites to meet before taking such a course. For example, Waukesha County Technical College in Waukesha, Wisconsin, offers training in conduit bending, but it is part of an advanced level course involving learning about other electrical work.
If you are looking to gain such a skill while breaking into the field of electrical work and becoming a skilled electrician, technical colleges are your first stop. Conduit bending is one step in the larger process of understanding how to set up full conduits. This type of training will most likely be listed under a full apprenticeship as well, where skills such as conduit bending can be learned from a master electrician.
If you are already an electrician and looking to learn more about the skill, or maybe just brush up, there may be courses offered through your union. The courses are different from most colleges courses in that they tend to be geared just toward conduit bending. For instance, Local Union 606 in Florida offers a course in conduit bending, along with fabrication. Nonunion members may take the course at a higher cost. The North Texas Electrical Joint Apprenticeship and Training Committee, which is sponsored by the National Electrical Contractors Association and the International Brotherhood of Electrical Workers, offers a course in conduit bending to members who part of the International Brotherhood of Electrical Workers.
For individuals who prefer learning on their own and just want to know about conduit bending for home purposes, or a worker on the job who needs to learn the skill fast, there are a host of conduit bending manuals. "Conduit Bending And Fabrication with Quick Reference Guide" by American Technical Publishers offers step-by-step instructions on conduit bending. The book covers plenty of basics and goes over the use of hydraulic, mechanical and electrical benders. "Ugly's Conduit Bending" by Alan W. Stanfield is a more succinct guide designed to work as a reference during the work.
Free-ed offers web courses in conduit bending. The instructions are straightforward and offer plenty of diagrams for learning.
