17th Edition Exam Overview
In preparing for this assessment, students will have undergone an intensive training programme in the weeks or days prior. The test is sat at the conclusion of all learning modules. Although learning the information off by heart has clearly been discouraged, candidates should still ensure they’ve read the text comprehensively. It’s important not to rush through your course, and only look to sit the examination when ready. Individuals will need to have grasped the various ‘parts’ contained in the guide, inclusive of the appendices and definition sections.
The assessment itself is endorsed by the City & Guilds, and registered as the 2382-15 exam. Therefore, the respective courses aligned to this test will be numbered in the same way. Candidates should always ensure that they familiarise themselves with this detail prior to undertaking any learning programme, as the C&G will always operate this same system of identification.
In similarity to the 18th edition version, the test duration is 120 minutes. Given that there are sixty questions included, this accommodates two minutes per response. This should be more than an ample amount of time to complete the exam. All questions are presented in multiple-choice format. However, this does not necessarily drive down answer times. Many of the questions will be structured in ways that will make you follow a certain sequence or methodology to its conclusion, and you’ll therefore have to work through to the full logical, ending of each scenario before settling on an answer.
This is an ‘open-book’ exam, which means delegates are permitted to have a personal copy of the wiring regulations on their person. Furthermore, students are able to highlight elements of the book that may feel useful to their cause. Separation tabs can also be deployed to target key passages and chapters. However, candidates can only number, not write on, these. On this point, individuals should be cautious of being lulled into a false sense of security. Having possession of the book is useful, but it is not a substitute for appropriately preparing beforehand. Don’t rely on picking up information during the exam; the guide should act as a supporting crutch, not the driver behind all of your responses.
Candidates are also allowed to use a scientific calculator, and should ensure they’re equipped with this prior to entering the examination hall.
Question structure and format
Each ‘part’ of the 17th Edition guide will feature in the test. However, the volume of questions corresponding to each part of the book will vary throughout.
Unlike previous assessments conducted on earlier wiring regulation versions, the test is structured chronologically. That is to say, that it follows the same running order as the guide. Therefore, candidates should be able to easily identify what part of the book a specific question is alluding to, dependent on its position within the question framework. However, questions within the part itself will be randomly scheduled. For example, the questions will be set moving from Part 3 into Part 4, but, within Part 4, the questions may jump around internally within the section. A solid understanding of the regulations will allow you to still swiftly determine which segment of the book is being targeted.
As referenced, the ‘weightings’ of each part differ. These align to the following, bracketed amounts:
- Part 1: Scope, object and fundamental principles (4 questions, 7% of exam, questions 1-4)
- Part 2: Definitions (2 questions, 3% of exam, question 5-6)
- Part 3: Assessment of general characteristics (6 questions, 10% of exam, questions 7-12)
- Part 4: Protection for safety (15 questions, 25% of exam, questions 13-27)
- Part 5: Selection and erection of equipment (14 questions, 23% of exam, questions 28-41)
- Part 6: Inspection and testing (4 questions, 7% of exam, questions 42-45)
- Part 7: Special installations or locations (10 questions, 17% of exam, questions 46-55)
- Appendices (5 questions, 8% of exam, questions 56-60)
Notes to consider
There a couple of observations worth referencing here.
Firstly, if you consider the proportion of questions tethered to Parts 4,5, and 7, then one can easily infer that these are the areas which require most revision attention. Indeed, these three parts account for a massive 65% of the overall result. Ensure you plan your studying time with respect towards question amounts per section.
Secondly, although the book feels relatively overwhelming in scope, it’s worth pointing out that the questions are heavily weighted towards the front end of the book. A massive 55 questions out of 60 are derived from the first 300 pages of the book, which means only five responses are required from the guide’s last 100 pages. As this is mostly dominated by the Appendices, make sure you don’t drown in terminology or various tables and their figures. Again, the test is not assessing your grasp of industry jargon. It’s aiming to understand whether you could safely and competently deliver electrical installs in compliance with the regulations.
In your preparation, make sure that you spend adequate times on the sections that demand the most attention because of their content detail, and clearly review any topics that you feel less assured in.
What will the exam test me on?
As referenced, the test is designed to assess your capability in practically applying the regulations documented in the 17th edition book. But what does this actually look like? Amongst other elements, you’ll be expected to be able to:
- Confidently use the appendices, definition pages and index to locate information and deploy its contents accordingly.
- Have a firm understanding of health and safety legislation and best practice, and how the regulations complement statutory documentation (wiring regulations, despite their central importance, are not technically statutory guidelines, although can be utilised as supporting documentation in a court of law).
- Calculate earth fault loop impedance, voltage drops, and cable sizes for specific installs in correspondence to current carrying capacity.
- Understand which items in a circuit need to be inspected, and the sequencing of performing tests on electrical instalments.
- Articulate key elements to be considered when designing and erecting installations.
- Have a strong understand of potential risks and hazards, and which regulations serve to mitigate against their dangers.
- Identify correct types of over-current devices for installations.
- Articulate the difference between main and secondary bonding.
- Understand what actions can be taken to promote protection from shocks. This is inclusive of incidents potentially caused by both direct and indirect contact.
- Have a decent understanding of various installs conducted in ‘special’ locations, and the main watch-outs to ensure their successful execution
- Be able to identify, locate, and apply specific regulations based on particular contexts and works demands.
If you feel confident in your knowledge on the above, and prepare thoroughly, then you should be able to comfortably get through the examination. The pass rate is high for this test, but please don’t allow any room for complacency!
Please digest the information contained in this article, and build an appropriate revision plan to complement your current competency level. If you require any further information on the content, structure or format of the exam, then please either liaise with your course convenor, or consult an industry professional.
Best of luck!
