Installation Rules Exam Preparation Guide – Part 2
What Is the Installation Rules Exam in South Africa?
The Installation Rules Exam is a mandatory regulatory assessment for electricians in South Africa who wish to register at specific levels and legally issue a Certificate of Compliance (CoC). This guide explains how the exam works, what it covers, and how to prepare strategically — not just hit-or-miss.

Understanding SANS 10142 (The Wiring of Premises)
The foundation of the Installation Rules Exam is SANS 10142‑1, the South African National Standard governing the wiring of premises. It sets the minimum safety requirements for electrical installations. The exam frequently tests your ability to locate, interpret, and apply regulatory requirements from SANS 10142, including:
- Protection against electric shock
- Earthing and bonding requirements
- Circuit design and overcurrent protection
- Cable selection and installation methods
- Distribution board compliance
- Inspection, testing, and verification procedures
- Certification and issuing of a valid CoC
Who Must Write the Installation Rules Exam?
You are typically required to pass the Installation Rules Exam if you want to:
- Register as an Installation Electrician
- Register as a Master Installation Electrician
- Legally issue a Certificate of Compliance (CoC)
- Take responsibility for electrical installation work
How the Installation Rules Exam Is Structured
There are two national examination papers:
- Paper 1 – Primarily theoretical interpretation of regulations
- Paper 2 – Includes both regulatory interpretation and electrical calculations
Each paper:
- Is 3 hours long
- Is marked out of 100
- Requires a minimum pass mark of 50%
Installation Rules Exam Pass Requirements
To qualify, you must achieve at least 50% in Paper 1 and 50% in Paper 2. Failing one paper requires rewriting only that specific paper. The exam does not reward memorisation. It evaluates:
