Course overview

Why take this 2391 Course

Worth Knowing: A 2391 qualification is currently required in order to gain your JIB grading as an approved electrician. There are initial (2391-50) and periodic (2391-51) qualifications available but you can save time and money with our combined 2391-52 course. The course has been introduced to streamline and simplify the qualifications required to carry our advanced inspection and testing. 

What are the entry requirements?

You must be over 18 and be up to date with industry requirements. This course is intended to be taught to experienced electrical installers who have previous training and experience of inspection and testing. Essentially you should be working in the electrical industry and involved with the inspection and testing process before taking this advanced course. It is also useful for you to have an understanding of 3 phase systems. If you have limited experience, you may wish to consider taking the Level 2 Fundamental Inspection and Testing qualification 2392. This course is designed to be taught for those who already know the fundamentals of inspection and testing but need to progress their skills. It is essential you have a good up to date understanding of BS 7671: IET Wiring Regs and up to date 18th edition course is recommended.

Note: There is no practical training, as such we strongly recommend you have 6 months testing experience before taking this course:

  • If you have no previous training inspection and testing you should take our C&G 2392 Course.
  • If you have taken a Step 3 2365 Diploma with Trade Skills 4U we can book you on at a reduced cost of £945

C&G 2391-52 Course Content:

The course will cover the specific methods of inspecting and testing all types of installations, whether single or three-phase, to the current requirements of BS 7671. It covers the inspection and testing techniques as given in IET Guidance Note 3 and how to professionally complete Certification and Reports.

The first 2 days of eLearning are particularly useful not only for the course but after you have finished as the eLearning is mobile friendly and with unlimited access you can use the content again and again should you need to refresh a particular test. This eLearning module has been designed to refresh your knowledge of the inspection and testing process for single and three phase installations, ensuring you are fully prepared for your lessons. Tests covered:

  • Continuity of protective conductors
  • Continuity of ring final
  • Insulation resistance
  • Earth electrode resistance
  • Polarity and phase sequencing
  • Earth fault loop impedance (Ze and Zs@DB)
  • Prospective fault current
  • Earth fault loop impedance (Zs)
  • RCD

Key areas covered include:

  • Safe isolation of electrical circuits and installations
  • Requirements for initial verification of electrical installations

Frequently asked questions

What experience do I need?

Entry to this qualification requires you to have ‘experience and knowledge of inspection and testing.’ It is useful for you to have taken the entry level City & Guilds 2392 Level 2, if you’re new to testing and inspection. Not mandatory, but certainly useful. It is ideally suited to those who have completed an NVQ or Level 3 diploma which would have covered fundamental inspection and testing. We also recommend you have industry experience as the course is taught at a higher level than most and draws on real world experience. An understanding of 3 phase is highly recommended.

What does this package allow me to do?

The course gives you the confidence to competently carry out Initial Verification and Periodic Inspection and Testing. It also gives you the certification needed to become JIB Approved as well as making membership with one of the Industry Certification Schemes an easier process. This course also gives you the knowledge and understanding needed to compile professionally detailed reports on the condition of electrical installations.

Is it difficult, I have heard the old 2391 was?

Like any assessment, it assesses your ability to do the job. If you can inspect and test and understand why and how, the exams and assessments shouldn’t be too hard. We pride ourselves on our pass rates and we know our training will give you the right knowledge and training needed to pass. It is expected that the new format of the assessments will make it much quicker to gain this qualification.

Does this course have a written exam?

No the hand written exams have been replaced by a short assignment which is completed during the course. It consists of a few questions which require written answers.
