Why Electrical Troubleshooting Training Matters
Unplanned downtime is one of the largest controllable costs in any plant or facility. Most of it comes from slow or inaccurate troubleshooting: parts swapped on a guess, faults that come back, and technicians working near energized equipment without a plan.
Today’s equipment raises the stakes. Variable frequency drives, solid-state controls, PLC inputs and outputs, and power quality problems produce symptoms that older troubleshooting habits can’t explain. Technicians need a structured method that works on both conventional and electronic equipment.
This course gives your team that method, along with the safety discipline to apply it under both Canadian and U.S. requirements.
Course Highlights
The course combines a systematic troubleshooting process with practical diagnosis on real equipment and circuits.
- A structured troubleshooting method that uses half-splitting, voltage-drop testing and root-cause analysis
- Safe work practices under CSA Z462, NFPA 70E, CSA Z460 and OSHA lockout requirements
- Motor, VFD, control circuit and power quality fault diagnosis
- Fault-scenario exercises worked on real NEMA and IEC drawings
Learning Outcomes
By the end of this course, you will be able to:
- Apply a repeatable troubleshooting process, from defining the problem through root cause and corrective action
- Plan troubleshooting tasks to meet CSA Z462 and NFPA 70E, including risk assessment, PPE, and verifying the absence of voltage
- Select and use multimeters, clamp meters, insulation resistance testers and infrared cameras safely and within their CAT ratings
- Read NEMA and IEC ladder diagrams and trace control logic to isolate opens, shorts and grounds
- Diagnose faults in transformers, fuses, circuit breakers, overload relays, contactors, timers and sensing devices
- Troubleshoot motor starting, reversing, two-speed and reduced-voltage control circuits
- Test motors using insulation resistance, polarization index and winding resistance measurements
- Diagnose common VFD faults and power quality problems such as harmonics, voltage unbalance and sags
- Use as-found and as-left records, trending and CSA Z463 or NFPA 70B practices to prevent repeat failures
You will leave with a practical method you can use on your next service call.
Course Approach
The course is vendor-neutral and built around the questions technicians actually face: what has failed, why, and how to prove it safely.
Each module ties theory directly to field tasks. Measurements are explained in terms of what a good reading looks like, what a bad one looks like, and what to do next.
Each day closes with a fault-scenario case study. Participants work through drawings, readings and symptoms to reach a diagnosis, just as they would on the job.
