About the SA Installation Rules Paper 2 Exam
Installation Rules Paper 2 is the second of two national theoretical examinations required for the South African wireman's licence (installation electrician). Based on SANS 10142-1, it tests the practical application of verification and certification procedures — inspection, insulation resistance, earth continuity, loop impedance, prospective short-circuit current, voltage drop and touch voltage calculations, fault-finding and CoC issuance for commercial and industrial low-voltage installations under the Occupational Health and Safety Act and Electrical Installation Regulations.
Assessment
A 3-hour written national examination of 100 marks administered by DHET through TVET colleges. Paper 2 focuses on SANS 10142-1 verification, inspection, testing, fault-finding, calculations and certification applied to commercial and industrial low-voltage installations. Both Paper 1 and Paper 2 must be passed for the wireman's licence theoretical requirement.
Time Limit
3 hours
Passing Score
50% (50 of 100 marks). If you score 75% or higher on either paper, you are permanently exempt from rewriting that paper. The second paper must be passed within 12 months of passing the first, otherwise both must be rewritten.
Exam Fee
Fees are charged by the registering TVET college or assessment centre and are not fixed nationally. Contact your college for the current examination and registration fee. (Department of Higher Education and Training (DHET) administers the Installation Rules examinations; registration as an installation electrician is with the Department of Employment and Labour after meeting all requirements including EWSETA unit standards.)
SA Installation Rules Paper 2 Exam Content Outline
Testing Procedures
Insulation resistance, earth continuity, loop impedance, bonding, ring circuits, PSCC and earth leakage testing per SANS 10142-1 section 8.6.
Verification and Certification
Visual inspection, test sequencing, defect lists, CoC completion and legal duties before issuing a Certificate of Compliance.
Calculations
Voltage drop, PSCC, touch voltage, loop impedance limits and conductor sizing for compliant protective device selection.
Fault Finding
Diagnosing open circuits, shorts, earth faults and nuisance RCD tripping using systematic isolation and test instruments.
Commercial Installations
Three-phase boards, sub-distribution, load balancing, labelling and verification of commercial LV systems.
Industrial Installations
Motor protection, starting methods, unbalanced neutral current, IT systems and specialised industrial compliance.
Earthing and Bonding
Electrodes, equipotential bonding, extraneous conductive parts and earth fault return paths.

Frequently Asked Questions
What is the difference between Installation Rules Paper 1 and Paper 2?
Paper 1 focuses on legislation, definitions, design principles and general SANS 10142-1 requirements including residential applications. Paper 2 focuses on verification, inspection, testing, calculations, fault-finding and certification procedures applied to commercial and industrial installations. Both papers are compulsory and require 50% to pass.
What pass mark do I need for Installation Rules Paper 2?
You need at least 50% (50 of 100 marks) to pass Paper 2. If you achieve 75% or higher on either Paper 1 or Paper 2, you receive a permanent exemption from rewriting that specific paper. The second paper must be passed within 12 months of passing the first.
What is the minimum insulation resistance required by SANS 10142-1?
Before energising a new or altered circuit, insulation resistance must be at least 1.0 MΩ when measured with a test voltage of at least twice the nominal system voltage (minimum 500 V), between conductors or between live conductors and the earth continuity conductor.
Who administers the Installation Rules examinations?
The Installation Rules national examinations are administered by the Department of Higher Education and Training (DHET) through TVET colleges and registered assessment centres, typically three times per year. Registration as an installation electrician with the Department of Employment and Labour requires passing both papers plus EWSETA unit standards.
