Electrical Troubleshooting – On-Site Only

$1499

Hands-On

3 Days

2.4 CEU

At the end of this seminar students will be able to:

  1. Understand electricity concepts like voltage, current, wiring, switches, and circuits.
  2. Learn how electricity applies to transformers, motors and common electrical devices.
  3. Safely perform electrical wiring, troubleshooting, and repairs
  • Why You should take this seminar

    About 70% of the time is spent working, hands-on, at a troubleshooting station with motor control circuits (operating at a safe, low level of 24 volts). This is a basic course, without any prerequisites, that helps you develop a solid foundation to build your troubleshooting knowledge and skills.

    You will learn techniques that will help locate faults quickly. Learn basic troubleshooting techniques in a logical sequence to cover all the standard control circuits.

    Gain practical, useful techniques that can be put into immediate use. This program is ideal for apprentice electricians just starting out, journeymen wishing to upgrade their skills, or any engineering, maintenance, operations, or management personnel who come into contact with electrical control systems in the course of their daily activity.
