The electrical programs offered at e-VOTECH are divided between electrician and electronics technician career tracks. Electrical work is by nature highly technical and requires specialized knowledge and skills for different types of work. However, electrical work has a core knowledge common to all fields. This course begins with electrical safety, and progresses through the basics common to all electrical and electronic workers.
The “Math for Craftsmen” program is a prerequisite for this course and prepares you for the more advanced electrical-specific math covered here. After completing this basics electricity and electronics course, you will begin the next phase of your training in the branch of electrical or electronics work you’ve chosen. People entering commercial electrical trade programs will ultimately meet certification requirements for the National Fire Prevention Association (NFPA) NFPA 70 standard. This national standard is the basis for state-level licensing in all 50 US states.
For people entering electronic technician fields, your programs will ultimately prepare you for Federal Communications Commission (FCC) radiotelephone technician licensing exam. Elective courses available through e-VOTECH will also help prepare you for certification exams in the different FCC licensing elements.
