2. 2392-10 Course Outline 3-day
Three-day Electrical Testing and Certification Course
Course Aims
1. This qualification is aimed at practising electricians who have not carried out inspection and
testing since qualifying or who require some update training before going on to achieve the City &
Guilds Level 3 Certificate in inspection, testing and certification of electrical installations (2391-10).
2. It is also suitable for those with limited experience of inspection and testing of electrical
installations, such as those:
a. Entering the industry from other engineering disciplines
b. Working in allied trades.
3. This qualification prepares candidates for the initial verification of electrical installation work.
Combined with suitable on-site experience, it would prepare candidates to go on to achieve the
City & Guilds level 3 Certificate in inspection, testing and certification of electrical installations
(2391-10).
Course Topics
th
Refresher on the 17 Edition wiring regulations (BS7671).
Preparation for initial inspection and testing.
Inspecting, testing and certifying, using IEE Guidance Note 3.
Hands-on practical work with test equipment.
Practising filling in the main standard certificates, forms and schedules.
Assessments
1. Component 101, Knowledge of Fundamental Initial Verification (online multiple choice test,
closed-book, 50 questions, 100 minutes).
2. Component 102, Practical Application of the Initial Verification (2-hour practical assessment).
The candidate must pass each assessment in order to gain the 2392-10 qualification.
Entry requirements
There are no formal entry requirements. However, candidates must have the potential and opportunity
to successfully gain the qualification. They should have basic knowledge and understanding of
electrical science and principles and experience of electrical installation work either within the electrical
contracting industry or an allied trade.
Course Structure
The course comprises three parts: Preparation for initial inspection and testing; Inspection; and
Testing, as detailed below.
Preparation for Initial Inspection and Testing
The candidate will demonstrate knowledge of:
• Requirements for Initial Verification
• Information required to correctly conduct the initial inspection and testing of an installation
• Statutory and non-statutory requirements and relevant guidance materials which apply to the
activity of inspecting and testing of electrical installations
• The need to comply with statutory and non-statutory requirements, guidance material for
particular locations and environments in which electrical installations are installed

• variation in cable length
State the difference between measurements taken for insulation resistance and conductor
resistance, and the order of magnitude that would be expected in each case
State the preconditions required for the performance of insulation resistance testing in terms of
• client consultation
• safety procedures and notices
State the precautions to be taken before testing insulation resistance in terms of

Complaints and Appeals
Any complaint or appeal should be made in the first instance direct to the Trans-Euro employee
involved. It should be escalated to the assessor or internal verifier/quality assurance coordinator if
satisfaction is not obtained. City & Guilds will not accept complaints or appeals made directly to them
unless this process has been exhausted. The full company Appeals Policy is available on request from
the Centre Secretary.

Data Protection
Any personal information Trans-Euro holds will only be used in the context of the business we conduct
with the candidate. This information comprises the candidate’s name, date of birth, sex, employer and
contact details.
The formal, detailed, Trans-Euro Data Protection Policy statement is available on request, held by the

Pre-Course Study and Reference Books
It would be of benefit to each delegate to obtain a book on Inspection & Testing in advance, either
NICEIC "Inspection, Testing & Certification" or IEE Guidance Note 3, and start using it, reading it,
memorising the sequence of tests and learning to use it as a reference book.
If the delegate applies to the NICEIC to join as a Domestic Installer, NICEIC will send a pack
of documents, including relevant publications as part of the "welcome pack".
It is essential that delegates are familiar with the different types of earthing system likely to be
encountered (TN-C-S, TT and TN-S). They should also remind themselves of earth fault loop
impedance testing, insulation resistance testing, and testing final circuits generally, especially ring final
circuits.
