  • 1. 027888 Certificate inFundamental Inspection, Testing and Initial Verification Scheme 2392-10 Prepared by Trans-Euro Engineering Services Ltd www.trans-euro.co.uk +44 (0) 1327 353 800 Trans-Euro Engineering Services Ltd - Consultancy, Training & Power Quality www.trans-euro.co.uk +44 (0) 1327 353 800
  • 2. 2392-10 Course Outline 3-dayThree-day Electrical Testing and Certification CourseCourse Aims1. 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 thRefresher 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 requirementsThere are no formal entry requirements. However, candidates must have the potential and opportunityto successfully gain the qualification. They should have basic knowledge and understanding ofelectrical science and principles and experience of electrical installation work either within the electricalcontracting industry or an allied trade.Course StructureThe course comprises three parts: Preparation for initial inspection and testing; Inspection; andTesting, as detailed below.Preparation for Initial Inspection and TestingThe 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© Trans-Euro Engineering Services Ltd.

  • 3. 2392-10 Course Outline 3-day • Essential and optional information to be contained on the Electrical Installation Certificate and Minor Electrical Installation Works Certificate and how the information is recorded.InspectionThe candidate will: • State the human senses that may need to be employed during the Initial Verification of an installation • Refer to and select the items to be checked during the inspection process for given systems and locations • State the requirements of the Electricity at Work Regulations for safe inspection and testing in terms of those carrying out the work and those using the installation and the building during the inspection and testing.TestingFor each topic below, the candidate will:InstrumentsState the need for instruments to be regularly checked and the need for compliance with therequirements of BS 7671 (current edition) and HSE Guidance Note GS 38.List the correct instruments, functions and appropriate scale(s) to carry out each test andexplain the reasons for each choice.SequenceState the recommended sequence of tests covered by this unit and the reasons for thatsequenceProtective ConductorsState the requirements which need to be considered for protective conductors in terms of: • earthing conductors • main protective bonding conductors • supplementary equipotential bonding conductors • circuit protective conductorsDescribe the need for, and methods of, verifying the continuity of protective conductors and theinterpretation of resultsState the relationship between conductor length, cross sectional area (csa) and resistanceState the effect of temperature on conductor resistance.Ring Final CircuitsState the effect on conductor resistance when cables are connected in parallel.Describe the need for, and the method of verifying the continuity of, ring final circuit conductorsand the interpretation of resultsState the relationship between conductor length and conductor resistance.Insulation ResistanceExplain, by example, the effect on insulation resistance of • cables connected in parallel • variation in cable lengthState the difference between measurements taken for insulation resistance and conductorresistance, and the order of magnitude that would be expected in each caseState the preconditions required for the performance of insulation resistance testing in terms of • client consultation • safety procedures and noticesState the precautions to be taken before testing insulation resistance in terms of • isolation of circuits and equipment© Trans-Euro Engineering Services Ltd.

  • 5. 2392-10 Course Outline 3-dayExplain the importance of confirming that protective devices are appropriate for the prospectivefault current.Verification of voltage dropState the methods of evaluating voltage dropDetermine compliance with voltage drop from given criteria.AssessmentsThe assessment questions in the exam will seek to examine the objectives listed under the syllabustopic headings with the percentage weightings shown below:Section Topic % Weighting No of items1 Preparation for Inspection and testing 16 82 Inspection 12 63 Testing 72 36 Totals 100 50Complaints and AppealsAny complaint or appeal should be made in the first instance direct to the Trans-Euro employeeinvolved. It should be escalated to the assessor or internal verifier/quality assurance coordinator ifsatisfaction is not obtained. City & Guilds will not accept complaints or appeals made directly to themunless this process has been exhausted. The full company Appeals Policy is available on request fromthe Centre Secretary.To obtain independent, informal advice before escalating to C&G HQ, our City & GuildsExternal Verifier contact details are: • Tony Massey • email: tony.massey@tesco.net • phone: 01480 890 538DisclaimerAchieving the full C&G 2382-10 qualification does not provide any guarantee of workmanship,performance, quality or status of the candidate during future endeavours such as plying his/her trade,applying for membership/enrolment of trade bodies/institutions, or for job seeking etcData ProtectionAny personal information Trans-Euro holds will only be used in the context of the business we conductwith the candidate. This information comprises the candidate’s name, date of birth, sex, employer andcontact details.The formal, detailed, Trans-Euro Data Protection Policy statement is available on request, held by theCompany Secretary.Pre-Course Study and Reference BooksIt would be of benefit to each delegate to obtain a book on Inspection & Testing in advance, eitherNICEIC "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 packof 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 beencountered (TN-C-S, TT and TN-S). They should also remind themselves of earth fault loopimpedance testing, insulation resistance testing, and testing final circuits generally, especially ring finalcircuits.© Trans-Euro Engineering Services Ltd.
