Verification and Certification for Electrical Installations (CoC) – What To Expect in the Installation Rules Exam

Introduction

The Installation Rules Paper 2 exam places strong emphasis on verification, inspection, testing and certification. This is confirmed in the official syllabus descriptions under “Verification & Certification.”

1. Earth Leakage Unit Testing

Past Paper 2 exam papers include specific questions requiring candidates to explain earth leakage testing procedures.

2. Inspection Requirements

Paper 2 questions also require candidates to list inspections performed on new or existing installations. Previous Paper 2 exam paper includes “Name TEN inspections…” as a full-mark question.

3. What Must Be Checked And Tested?

Before a Certificate of Compliance can be issued, the installation must be inspected and tested to verify that it complies with the required standards. The Paper 2 syllabus covers several key verification procedures, including:

• Visual inspection of wiring and distribution boards
• Circuit identification and labelling
• Earth continuity testing
• Insulation resistance testing
• Earth-fault loop impedance verification
• Earth leakage protection testing

These procedures ensure that the installation is electrically safe and compliant with regulatory requirements.

4. Certification (CoC) Requirements

The Certificate of Compliance is a key examination topic.

• Paper 1

  Paper 1 tests the legal and regulatory aspects, including:

  • Definitions related to the CoC
  • Responsibilities of the registered person
  • Conditions under which a CoC must be issued
  • Legal compliance requirements

• Paper 2:

  Paper 2 tests the practical technical procedures, including:

  • Inspection checklists
  • Testing procedures
  • Verification of protective devices
  • Confirming installation compliance before issuing a CoC

Understanding both the legal and technical aspects is essential for passing the Installation Rules examinations. If you are preparing for the Installation Rules examinations, read our detailed Installation Rules Exam Guide to understand the structure of Paper 1 and Paper 2.

5. Documentation & Safety

The Paper 2 syllabus includes completing inspection sheets, recording test results, and confirming compliance with SANS 10142‑1.
