C&G Inspection & Testing Refresher - Online

Every electrician has to learn how to inspect and test, however some electricians find that they haven’t used this skill for some time, meaning the thought of a practical assessment or advanced inspection and testing course can be daunting. This course will refresh and improve on your existing knowledge giving you the confidence and skills required when carrying out inspection and testing on Single Phase and Three phase installations. It will give you the best chance of understanding the key aspects of the C&G 2391-52 course and the best chance of passing your practical assessments first time.

10 individual eLearning modules covering single and three phase testing including:

1. Continuity of circuit protective conductors (including main and supplementary bonding) (SP/TP)
2. Continuity of ring final circuit conductors (SP)
3. Insulation resistance (SP/TP)
4. Earth electrode resistance (including theory on test method E1, E2, E3 and practical demonstration on test method E1 – Fall of potential method.)
5. Polarity and phase sequencing (SP/TP)
6. Earth fault loop impedance (Ze and Zs at DB) (SP/TP)
7. Prospective fault current
8. Earth faut loop impedance (Zs)
9. Residual current device (RCD)
10. Knowledge checks (2 x 50 question online quizzes)

These modules are each broken down into individual sections including:

  • Procedure (theory) – Including plenty of images & voice overs. This is to talk students through the procedure including setting up the instrument and what the inspector is looking for in terms of results.
  • Practical demonstrations single and three phase. These are videos which show the tests in full.
  • Recording the tests. This section shows how to record the results following the demonstrations.
  • Verification of results. This section shows how to verify that the results comply with BS 7671 and are satisfactory.
  • Scientific principles. Where relevant, scientific principles are introduced to help learners better understand the science behind the test.
  • Knowledge check after each test around 10 questions after each section.
  • 2 x full length exam simulators designed to test full range of knowledge once course is complete.
