Important Course Details

    5 days
    We will be running the City and Guilds 2391-50 Initial Verification course at our Watford, London and Stockton-On-Tees, Teesside electrical training venues.
    • Although there are no formal qualifications required for this electrical verification course, it is expected that you should have a good knowledge and understanding of electrical science and principles. Previous experience of electrical installation work, either within the electrical contracting industry or an allied trade is essential.
    • It is best suited to those who are working within the electrical industry and are actively involved with the inspection and testing process with previous experience of live boards. It is also useful for you to have an understanding of 3 phase systems.

There is a very small element of practice, however, no formal practical training will be provided.

You should also have a good understanding of the latest IET Wiring Regulations BS7671 and an up-to-date 18th Edition certificate.

In summary, this course is designed for those who want to progress their testing and inspection skills. Therefore, a good understanding of the fundamentals is essential. It is strongly suggested that you have 2 years experience working with inspection and testing as a practising electrician before taking this course.

If you have no previous training or experience or need a refresher then the City and Guilds 2392-10 Fundamentals and Initial verification (Level 2) course contains both practical and theory and is good practice before progressing to the City & Guilds 2391 level 3 courses.

Please call our training team for more information if you are concerned about your eligibility.

    This course will include a multiple-choice examination (40 questions – 80 minutes), a short answer test (1 hour) and a practical test (2 hours).
    • City and Guilds 2391-50 is a theory-based course; you can expect to be in the classroom carrying out important theory, based on initial verification. Taught by our experienced, friendly and helpful electrical training tutors, we will guide you through all of the modules and prepare you as much as possible for the examinations and practical assignments that you will have to complete at the end of the course. We try at all times to keep our training groups with a small group of learners to ensure you get plenty of one-on-one time with our tutors, to ensure all of your questions are answered and you get the best electrical learning experience.
    Those who successfully complete with course will receive a City & Guilds 2391-50 Level 3 Award in Initial Verification.
