Understanding & Complying with SANS 10142-1:2024 (Edition 3.2) – Wiring of Premises
2-Day Live Online Training Course
Dates: 14–15 July 2026
Master South Africa’s Latest Electrical Wiring Regulations
Stay compliant with the latest SANS 10142-1:2024 Edition 3.2 Wiring Code and ensure your electrical installations meet current South African safety standards.
This intensive 2-day online electrical compliance training course is designed for electrical engineers, contractors, technicians, consultants, inspectors, maintenance professionals, and anyone responsible for electrical installations, testing, inspection, or certification.
With major updates introduced in Edition 3.2 (July 2024), understanding the revised requirements has become essential for legal compliance, workplace safety, and professional competency.
Course Overview
SANS 10142-1 is the South African national standard governing the design, installation, testing, inspection, and certification of low-voltage electrical installations.
Since its first publication, the standard has evolved significantly to accommodate modern electrical technologies including:
- Electric Vehicle (EV) Charging Stations
- Solar PV (On-Grid & Off-Grid) Systems
- UPS & Backup Power Systems
- Secondary Distribution Networks
- Hazardous Area Installations
- Renewable Energy Integration
- Modern Earthing & Protection Systems
The 2024 Edition 3.2 introduces substantial revisions affecting electrical contractors, engineers, inspectors, facility managers, and installers.
Key updates include:
- Revised referenced standards
- New voltage drop requirements
- Updated busbar requirements
- Changes to earthing and earth continuity conductors
- Revised touch voltage requirements
- New installation requirements for renewable energy systems
- Updates to testing and verification procedures
- Removal of the previous 60W per lamp load calculation requirement
- Improved guidance for Certificates of Compliance (CoC)
Failure to understand these changes may result in non-compliant installations and costly corrective work.
This highly practical course explains every major amendment using real-world examples, calculations, demonstrations, and practical discussions.
