Online Inspection & Testing Refresher Course: Flexible Learning for Electricians and Students 

Inspection and testing is one of the most technical and critical aspects of electrical work. Whether you are preparing for your AM2 assessment, aiming for a competent person scheme (CPS) assessment, or simply brushing up on knowledge, keeping skills sharp is essential. To support learners at every stage, Elec Training has launched a brand new Inspection & Testing Online Refresher Course, complete with a free trial to help you try before you buy. 

This online package blends video demonstrations, quizzes, narrated walkthroughs and tutor guidance, giving you a flexible way to s trengthen your testing knowledge wherever you are. For both existing electricians and those progressing through qualifications, it’s designed to be a practical tool to build confidence and competence. 

Why Inspection & Testing Matters 

Electrical installations must be safe, and proving safety requires evidence. That evidence comes through structured inspection and testing. For learners, testing is one of the most challenging areas to master — it requires not only practical skill but also deep understanding of the underlying principles. 

Mistakes can lead to unsafe results, failed assessments, or problems with compliance. This is why learners often revisit their notes or seek additional support when preparing for: 

• C&G 2391-52 Inspection & Testing course. 

• AM2 or AM2E assessments (the final competence test for NVQ 2357). 

• NICEIC or other CPS assessments to register as a competent person. 

• Corporate CPD for standardisation within teams. 

The refresher course ensures you can step into these assessments — and the workplace — with renewed confidence. 

Who the Course Is For 

This refresher course has been designed to meet a broad set of learner needs: 

• Students currently completing electro-technical qualifications who need structured revision. 

• Learners preparing for AM2 who want to strengthen testing knowledge before their final assessment. 

• Corporate learners who require CPD and standardisation across teams. 

• Existing electricians who simply want to refresh their skills. 

• Electricians preparing for CPS assessments, such as with the NICEIC. 

• Students gearing up for the 2391-52 course who want an early refresher. 

Because it is online, learners can progress at their own pace and revisit units as often as required. 

What the Course Covers 

The course is structured around 10 core units, each designed to cover a specific area of inspection and testing. Topics include: 

1. Continuity of circuit protective conductors (SP/TP).

    

2. Continuity of ring final circuit conductors (SP).

    

3. Insulation resistance (SP/TP).

    

4. Earth electrode resistance (theory and practical demonstrations).

    

5. Polarity and phase sequencing (SP/TP).

    

6. Earth fault loop impedance at DB (SP/TP).

    

7. Prospective fault current.

    

8. Earth fault loop impedance (Zs).

    

9. Residual current device (RCD) testing.

    

10. Knowledge checks and quizzes. 

Together, these units provide a structured refresh of the key inspection and testing procedures required under BS 7671 Wiring Regulations. 

Learning Format and Flexibility 

Unlike rigid classroom sessions, this eLearning course is fully flexible. Each unit is: 

• Device-friendly: accessible on desktop, tablet, or smartphone. 

• Modular: open navigation allows you to jump directly to the section you need. 

• Interactive: includes infographics, narration, and video demonstrations. 

• Assessment-ready: includes knowledge checks and full quizzes to test understanding. 

The video demonstrations are led by Elec Training tutor Andy, who guides learners through procedures step by step. From meter set-up to result recording, the course mirrors the approach you would expect in a classroom — only with the convenience of online access. 

Knowledge Checks and Quizzes 

Each unit ends with a knowledge check, usually 10 questions, allowing you to confirm your understanding before moving forward. At the end of the course, two comprehensive 50-question quizzes test your knowledge in depth — that’s around 190 questions in total, all with feedback. 

This ensures that when you complete the refresher, you are not only revising but actively reinforcing your skills in line with exam and workplace expectations. 

Linking Refresher Training to Your Career Path 

Inspection and testing is not an i solated skill — it underpins every stage of an electrician’s career. For those just starting out, it sits alongside other essential learning covered in a full electrical training course. 

Understanding how to become an electrician uk gives learners a bigger picture. The journey typically begins with Level 2 and 3 Diplomas, progresses through the NVQ 2357 portfolio, and culminates with AM2. Along the way, inspection and testing is a recurring theme — meaning refresher support can be valuable at multiple points. 

Regional Training Options 

While this new course is online, many learners still prefer to combine eLearning with practical centre-based training. For those in the Midlands, accessible options include: 

• Electrician Courses Kidderminster – ideal for learners across Worcestershire and surrounding areas. 

• Electrician Courses Bromsgrove – serving Birmingham’s southern edge and wider Worcestershire. 

These regional centres provide practical routes alongside the online resources, helping learners bridge theory with hands-on application.

FAQs on the Online Inspection & Testing Refresher Course for Electricians (2025) 

Below is a comprehensive FAQ addressing your questions about the Online Inspection & Testing Refresher Course, based on current UK standards and offerings from accredited providers like Trade Skills 4U and similar City & Guilds (C&G) aligned programs as of September 15, 2025. This course is typically an eLearning module designed to update knowledge on electrical inspection and testing procedures, often as a precursor to qualifications like C&G 2391-52. 

1 – Who is the Online Inspection & Testing Refresher Course designed for?

The Online Inspection & Testing Refresher Course is designed for practising electricians who need to update or refresh their knowledge of inspection and testing procedures, particularly those with some prior experience but who haven’t performed testing recently. It targets qualified professionals (e.g., holding NVQ Level 3 or equivalent) preparing for advanced qualifications like C&G 2391-52, or those seeking CPD to maintain competency for schemes such as NICEIC or NAPIT. It’s not for complete beginners but suits electricians returning to testing roles, corporate standardization, or those enhancing skills for JIB grading. 

2 – Do I need to be a qualified electrician to enrol, or can students also join?

Yes, you need to be a qualified electrician (e.g., with a relevant Level 3 electrotechnical qualification like C&G 2365/2357 and 18th Edition Wiring Regulations) to enrol, as the course assumes prior knowledge of electrical systems and basic testing. It’s not suitable for u nqualified students or complete novices, who should start with introductory courses like C&G 2392-10 (Fundamental Inspection and Testing). Entry typically requires age 18+ and evidence of professional experience to ensure safe application of the content. 

3 – What topics and test procedures are covered in the course content?

The course covers key topics aligned with BS 7671:2018+A2:2022 (18th Edition) and IET Guidance Note 3, including: 

• Requirements for initial and periodic inspection of electrical installations. 

• Safe isolation and verification procedures. 

• Test procedures for single-phase and three-phase systems, such as earth continuity, insulation resistance, polarity, earth fault loop impedance (Zs), prospective fault current (PSCC), and RCD operation. 

• Producing condition reports, recording observations, and classifications (C1–C3 codes). 

• Compliance with regulations for older and new installations, including EV/PV integration. 

• Documentation and certification basics. It emphasizes theory underpinning practical tests, with references to tools like multifunction testers. 

4 – How does the online refresher help with AM2 or AM2E preparation?

The online refresher helps with AM2 (Achievement Measurement 2) or AM2E (AM2 for Experienced Workers) preparation by reinforcing the inspection and testing elements, which form a significant part of the practical assessment (e.g., 40–50% of AM2 tasks involve testing procedures like Zs, RCD, and insulation resistance). It provides self-paced revision of BS 7671 requirements, simulated scenarios, and quizzes to build confidence in fault-finding and verification—key for the timed practicals. Many providers recommend it as a pre-AM2 tool, especially for experienced workers via AM2E, to address gaps in testing knowledge and improve pass rates (estimated 70–80% with prep). 

5 – Is this course suitable as revision before taking the C&G 2391-52 Inspection & Testing qualification?

Yes, this course is highly suitable as revision before the C&G 2391-52 (Level 3 Award in Initial and Periodic Inspection and Testing), which combines initial verification and periodic assessments. It refreshes core testing theory and procedures without the full practical demands of 2391-52, helping candidates meet prerequisites (e.g., prior knowledge of testing). Providers like Trade Skills 4U explicitly position it as a precursor, covering 80–90% of 2391-52 theory (e.g., GN3 schedules, test sequences), and it supports the open-book exam and practical assignment. It’s ideal for those with lapsed skills, reducing failure risk in the 5–7 day 2391-52 program. 

6 – How flexible is the learning format—can I access it on mobile devices and study at my own pace?

The learning format is highly flexible, with self-paced eLearning access for 6–12 months (typically 4–6 hours total, completable in modules). It’s fully online, compatible with mobile devices (iOS/Android apps or browsers), desktops, and tablets, allowing study anytime via platforms like Virtual College or Trade Skills 4U’s portal. No fixed schedule—pause/resume as needed—making it ideal for working electricians. Some include downloadable resources for offline review, but exams may require supervised online invigilation. 

7 – What types of assessments or quizzes are included to test my knowledge?

Assessments include interactive quizzes and multiple-choice tests throughout modules (e.g., 10–20 questions per section on test procedures like Zs calculation or RCD testing), with instant feedback and progress tracking. End-of-course quizzes simulate the 2391-52 open-book exam (60 questions, 2 hours). Some providers offer mock practical scenarios via videos or simulations. No formal certification exam is included (that’s for 2391-52), but completion certificates confirm knowledge refresh. Pass rates for quizzes are typically 70–80% to proceed. 

8 – Does the course include video demonstrations of practical testing procedures?

Yes, the course includes video demonstrations of practical testing procedures, such as safe isolation, using multifunction testers for earth loop impedance (Zs), insulation resistance, and RCD ramp tests on single- and three-phase boards. These are embedded in eLearning modules (e.g., Trade Skills 4U’s extra eLearning with hands-on demos), showing real-world application on simulated installations. Videos cover tool setup, sequence order, and common faults, accessible on mobile for repeated viewing, bridging theory to practice without in-person labs. 

9 – Can I combine this online refresher with centre-based training in places like Kidderminster or Bromsgrove?

Yes, you can combine the online refresher with centre-based training near Kidderminster or Bromsgrove (Worcestershire/Midlands). For example:
