City & Guilds 2391-52
Course Objectives

A 2391 qualification is currently required in order to gain your JIB grading as an approved electrician. There are individual Level 3 awards: (2391-50) Initial Verification and (2391-51) Periodic Inspection 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 out advanced inspection and testing. Until July 2017 most people would take a combined 2394/2395 course which required 1 closed book multiple choice online exam, 2 closed book written/online exams and 4 associated assessments and 2 practical assessments. This new qualification only requires 1 online multiple-choice exam, 1 written assignment, 1 associated assignment and 1 combined practical assessment.

Course Duration

6.5 Days – Monday to Friday 8:30 to 16:30 week 1 & Monday 8:30 to 16:30 week 2. The additional ½ day attendance will be required for the combined practical assessments.

Course Content

The course and qualification is based on the current “IET Guidance Note 3 - Inspecting & Testing” (GN3) to verify compliance with the current “Requirements for Electrical Installations - IET Wiring Regulations 18th Edition – BS 7671”

The content follows C & G 2391-52 syllabus and mainly covers the requirements for:
  • Health and Safety and associated legislation, codes of practice and regulations.
  • Safe isolation of electrical circuits and installations
  • Requirements of initial verification and periodic inspection and testing
  • The safe testing and commissioning of electrical installations including the use of test equipment.
  • Inspection requirements of initial verification and periodic inspection including classification codes.
  • Initial verification testing methods.
  • Periodic testing requirements and associated fault diagnosis.
  • Interpretation and verification of test results
  • Completion of electrical installation certificates and electrical installation condition reports, inspection schedules and schedule of test results.
The Course would also include:
  • Principles and use of overcurrent protective devices and RCD’s
  • Protection methods provided by supply systems.
  • Earthing systems, protective conductors, types and use.
  • Fault, short circuit and overload protection principles.
  • Cable types and factors that affect test results, and typical cable faults.
  • Cable selection principles.
  • International protection index and application.
  • ADS and Earth Fault Loop Impedance requirements and verification methods.
  • Various practical exercises to practice and confirm electrical inspection and testing principles.
Who should attend?

The course is aimed at practicing electricians who have not carried out initial verification or periodic inspection, testing and fault diagnosis since qualifying who require an update and enhancement of knowledge, skills; as well as progression route to other City & Guilds qualifications. This qualification is also suitable for those with limited experience of initial verification and periodic inspection and testing and fault diagnosis and for those entering the industry from allied trades.


There will be a 2 hour multiple-choice online open book exam, a written assignment, an associated visual assessment and a half day combined Practical Assessment.

You must be up to date with industry requirements. Ideally you should be working in the electrical industry and involved with the inspection and testing process. This course is designed for those who already know the fundamentals of inspection and testing but need to progress their skills.

Delegates must have the potential to achieve and are expected to have a working knowledge and understanding of electrical principles, wiring systems and be conversant with current electrical installation practice. It is not mandatory but it is recommended that delegates have achieved a City & Guilds 2382 qualification covering “Requirements for Electrical Installations - IET Wiring Regulations 17th Edition - BS 7671”, or have a working knowledge of the requirements. An additional preparation course or home study may be taken prior to commencement to gain essential underpinning knowledge. Candidates must be over 18 years old.
