The South Africa Millwright Artisan Trade Test is the competency-based assessment for the millwright, one of the few designated trades that combines both mechanical and electrical work. It is moderated by the National Artisan Moderation Body (NAMB) under the Quality Council for Trades and Occupations (QCTO), and a successful candidate receives a Section 26D national artisan trade certificate. The trade test is practical and integrated, with oral and written knowledge questioning, so QCTO/NAMB do not publish a fixed multiple-choice question count. Trade-theory covers mechanical fitting, electrical principles to SANS 10142-1, drives, bearings and gearboxes, PLC and control basics, hydraulics and pneumatics, shaft alignment, fault-finding and OHS Act safety. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1A millwright is a dual-discipline artisan. Which combination best describes the core scope of the South African millwright trade?
2The South African national trade certificate for a millwright is issued under which legislation once the candidate passes the external trade test?
3A bearing is marked '6205'. In the deep-groove ball bearing designation system, what does the '05' indicate?
4What is the synchronous speed of a 4-pole three-phase induction motor running on a 50 Hz supply?
5Which standard is the South African code for the wiring of premises (low-voltage installations) that a millwright must comply with?
6Ohm's law relates voltage, current and resistance. If a heater element draws 10 A from a 230 V supply, what is its resistance?
7When aligning a motor to a pump using the rim-and-face method, what does the FACE reading primarily measure?
8Before correcting any shaft misalignment, a millwright must first check and correct which condition?
9In a hydraulic system, which component converts fluid pressure and flow into linear mechanical motion?
10A hydraulic cylinder has a piston area of 0.005 m2 and the system pressure is 10 MPa. What force can the cylinder exert?
About the Millwright Trade Test Exam
The millwright artisan trade test is South Africa's competency-based assessment for the dual mechanical-and-electrical trade. Moderated by NAMB under the QCTO, it is a practical, integrated test with knowledge questioning rather than a fixed-count multiple-choice paper. A successful candidate is issued a Section 26D national artisan trade certificate.

Frequently Asked Questions
How many questions are on the South African millwright trade test?
The millwright trade test is a practical, competency-based assessment with integrated oral and written knowledge questioning, so QCTO/NAMB do not publish a fixed multiple-choice question count. This free bank of 100 trade-theory questions helps you prepare for the knowledge component.
What is the passing requirement for the millwright trade test?
The trade test is marked Competent or Not Yet Competent across all integrated mechanical and electrical assessment tasks. You must be assessed Competent in every task to be issued the Section 26D national artisan trade certificate.
Who moderates and certifies the South African millwright trade test?
The trade test is moderated by the National Artisan Moderation Body (NAMB) under the Quality Council for Trades and Occupations (QCTO). On passing, you receive a Section 26D national artisan trade certificate issued under the Skills Development Act.
What topics does the millwright trade theory cover?
Because the millwright is a dual trade, the theory covers both mechanical fitting and electrical principles, plus drives, bearings and gearboxes, PLC and control basics, hydraulics and pneumatics, shaft alignment, fault-finding and OHS Act safety. South African questions use SANS standards such as SANS 10142-1, not BS 7671 or the NEC.
Why is the millwright described as a combined mechanical and electrical trade?
A qualified millwright installs, aligns and maintains mechanical machinery such as gearboxes, bearings, pumps and conveyors, and also wires, connects and fault-finds electrical motors and control circuits. This dual scope is why the trade test assesses both disciplines.
Is this free millwright practice test useful preparation?
Yes. The 100 research-based questions cover the full mechanical and electrical trade theory with a teaching explanation for every answer, plus free daily AI tutor interactions. All content is free forever and updated for 2026.
