Inspection and Testing CG2391-52 L3
This qualification is intended for experienced electricians who have some experience, but have never gained formal qualifications in inspection and testing. It is also aimed at competent electricians who may wish to update and reaffirm their skills.
Your learning will be underpinned by a range of practical application, through understanding:
- the continuity of protective conductors
- the continuity of ring final
- insulation resistance
- earth electrode resistance
- polarity and phase sequencing
- earth fault loop impedance (Ze and Zs@DB)
- prospective fault current
- earth fault loop impedance (Zs) RCD
The test specification for this qualification:
- Multiple-choice online test: Initial and Periodic Inspection and Testing. Duration: 120 minutes / Number of questions: 60*
- Practical assessment: Visual inspection of Electrical Installations. Duration: 30 minutes (closed book)
- Practical assessment: Combined Initial Verification and Periodic Inspection of an Electrical Installation. Duration: 150 minutes#
- Written paper – short answer questions: Combined Initial Verification and Periodic Inspection of an Electrical Installation. Duration: 80 minutes*
* This is an “open book” exam, so candidates can refer to BS7671, GN3 and On-Site Guide during the exam.
# Candidates may refer to BS7671 or GN3 for verification of compliances only, not as a full guide to testing.
Course title: City & Guilds 2391-52 Level 3
Certificate: Inspection and Testing of Electrical Installations
Duration: 5 days to include the assessments.
Class times: 08:30-17:30 plus home study.
Course fee: £945 (includes registration and exam fees)
Candidates must have knowledge and understanding of electrical science and principles, and experience in electrical installation work, either within the electrical contracting industry or an allied trade. Minimum age 18.
A relevant qualification, such as City & Guilds 2360, 2330, 2357, or a Level 3 2365 or 5357 would be sufficient evidence of this.
Candidates should also hold a current 18th Edition qualification.
This course allows candidates to progress to the Level 4 Award in Design and Verification of Electrical Installations (2396).
