The 5 Point Fault-Finding approach is generally the recognised method of how to approach fault-finding, the most important step in this process is to gather as much information as possible with regards to what is happening when the fault occurs and what problem the fault exactly causes.

The 5 steps are as follow:

  1. Gather Information – Ask as many people as possible who were there, when and how the fault occurred
  2. Analyse Information – decide the probable cause based on past experience and training
  3. Investigate – now attempt to find the fault from your analysis
  4. Rectify – once found, safely repair the fault
  5. Test – when the fault is put right & restored, test your work before re-energising

The following is a concise list of the standard faults we would expect to see, that most commonly cause an electrical circuit to stop operating correctly.

  • Loss of Supply
    Cause – Loose Connection – Tripped MCB – Blown Fuse – Internal Fuse
  • Earth Fault
    Tripping Circuit Breaker/RCD – device will not remain engaged or will for a short while – then possibly a circuit on their contains the issue
  • Dead Short
    Phase to Neutral/Phase to Phase – possible cause – main fuse at origin blown
  • Correct Protective Device in Place
    Type B – Type C – Type D Circuit Breakers / S’Type RCD’s
  • Defective Components
    Switches – Relays –Contactors, not functioning correctly, possibly needs replacement
  • Breakdown of Control Circuits
    Internal Wiring/PCB’s & Electronics
  • Reversed Polarity
    At supply origin – at a single outlet (Phase Neutral reversed or neutral earth reversed) or at a single fitting (Phase – Neutral) – Live Test Vs Dead Test.
  • Most Common in an Industrial Setting
    Control Circuits (Internal Fuses) – Contactors (Breakdown of Parts)  – 3PH motors (Loss of  Phases &/Or burnt out coils) – Single Phase Motors – (Carbon Brushes)
  • Common Faults on Newly Installed Work
    Reversed Polarity – Discrimination – loose connections – Protective Devices –Faulty Portable equipment
