Industrial Electricity & Troubleshooting Electrical Control Circuits
National Technology Transfer, Inc.
Delivery Method
Seminar
Target Audience
You should attend if you are involved with the installation, service, care, or inspection of electrical systems; including electricians, system installers, inspectors, maintenance personnel, troubleshooters, contractors, safety professionals, facilities managers, engineers, testers, apprentices, consultants, linemen, and utility company personnel who have not had formal education in the NEC® or who need to be updated on the current standards.
Summary
Learn the Nature and Applications of Industrial Electricity and How to Wire, Operate, and Troubleshoot a Circuit, All in One Combination Seminar!
Description/Agenda
4 day Hands-on
3.2 Continuing Education Credits
Understand the basics of electricity generation and
delivery in the first half of the course. Learn to
safely use the proper measurement instruments and tools
to understand the characteristics and properties of
electrical signals. The terms voltage, current and
impedance (resistance) will become standard in your
electrical conversations.
In the second half of this course, you will learn how
to effectively diagnose electrical control circuit
problems. You will experience live circuit faults in a
real world scenario. Become a confident and safe
troubleshooter from techniques presented.
Approximately 60% of the time is spent working
hands-on with the same controls circuits and devices
commonly used on HVAC systems, pump systems, hydraulics,
conveyors and automated machines.
