EWRB/Aspeq

The NZ EWRB Electrician Registration (Regulations) Examination is the written theory exam for electrician registration in New Zealand, set by the Electrical Workers Registration Board and delivered by Aspeq. It is a computer-based multiple-choice exam taken with permitted reference materials, covering the Electricity (Safety) Regulations 2010, AS/NZS 3000 Wiring Rules (MEN earthing, RCDs, disconnection times, voltage drop), testing and verification, prescribed electrical work and risk categories, certification (CoC, ESC and RoI), safe isolation, the electrical codes of practice (NZECP 34/50/51), and installation requirements. Separate practical assessments cover hands-on competence. The Aspeq exam fee is NZ$149.50 plus GST, and results are released within about 24 hours. This free prep includes 100 research-based practice questions with explanations and an AI tutor.

1Which New Zealand legislation sets out the primary safety requirements for electrical installations, appliances, and the carrying out of prescribed electrical work?
A.The Building Act 2004
B.The Electricity (Safety) Regulations 2010
C.The Health and Safety at Work Act 2015
D.AS/NZS 3000 alone
Explanation: The Electricity (Safety) Regulations 2010 (made under the Electricity Act 1992) are the principal NZ secondary legislation governing electrical safety, prescribed electrical work, certification, and the safety of works, installations, fittings and appliances. AS/NZS 3000 is cited by the Regulations but is itself a Standard, not the legislation.
2Under the Electricity (Safety) Regulations 2010, what term describes electrical work that, by law, may only be carried out by an authorised person and that generally requires certification?
A.General electrical work
B.Prescribed electrical work (PEW)
C.Notifiable work
D.Restricted electrical work
Explanation: Prescribed electrical work (PEW) is the defined category in the ESR 2010 covering work on electrical installations, fittings, works and appliances that must be done by an authorised (registered/licensed) person and certified. The risk categories of PEW (low, general/medium, high) determine the certification required.
3Which body maintains the register of electrical workers and sets the competence and registration requirements for electricians in New Zealand?
A.WorkSafe New Zealand
B.The Electrical Workers Registration Board (EWRB)
C.Standards New Zealand
D.The Energy Safety Service
Explanation: The Electrical Workers Registration Board (EWRB) registers and licenses electrical workers, sets competence requirements, and administers registration exams (delivered by Aspeq). WorkSafe's Energy Safety function regulates electrical safety more broadly, but the EWRB owns registration.
4Which document must be issued for ALL general-risk and high-risk prescribed electrical work to confirm the work complies with the Electricity (Safety) Regulations 2010 and the relevant Standards?
A.A Record of Inspection (RoI)
B.A Certificate of Compliance (CoC)
C.An Electrical Safety Certificate (ESC) only
D.A building consent
Explanation: Regulation 65 of the ESR 2010 requires a Certificate of Compliance (CoC) to be issued for all general-risk and high-risk PEW. The CoC certifies that the work was carried out in accordance with the Regulations and AS/NZS 3000. An ESC is separately required when the work is connected/energised.
5What is the primary purpose of an Electrical Safety Certificate (ESC) as distinct from a Certificate of Compliance (CoC)?
A.It records an independent third-party inspection
B.It confirms the prescribed electrical work is connected and safe to energise and use
C.It replaces the need for a CoC on high-risk work
D.It is issued only for appliance repairs
Explanation: An ESC confirms that the installation has been verified safe to connect to the supply and is safe to energise and use. The CoC certifies design and installation compliance; the ESC is the safety-to-connect document, and must be issued when PEW is connected to the mains/energised.
6When is a Record of Inspection (RoI) required under the Electricity (Safety) Regulations 2010?
A.For all prescribed electrical work
B.For low-risk prescribed electrical work only
C.For high-risk prescribed electrical work, completed by an inspector before the work is considered complete
D.For appliance servicing only
Explanation: Regulation 72 requires an inspector to issue a Record of Inspection (RoI) for high-risk PEW. A CoC and an RoI must both be issued for high-risk work before it is considered complete, providing an independent verification of the higher-risk work.
7Which earthing system does AS/NZS 3000 specify as standard for low-voltage installations in New Zealand?
A.TT system with separate earth electrode only
B.Multiple Earthed Neutral (MEN) system
C.TN-S system with no neutral-earth link
D.IT system (isolated neutral)
Explanation: The Multiple Earthed Neutral (MEN) system is the standard earthing arrangement for LV installations under AS/NZS 3000 in NZ and Australia. The neutral and earth are linked (the MEN connection) at the main switchboard, providing a low-impedance earth fault return path.
8Where in an installation must the Multiple Earthed Neutral (MEN) connection (the neutral-to-earth link) be made?
A.At every final subcircuit
B.At the main switchboard
C.At the point of supply pole only
D.At each socket outlet
Explanation: Under AS/NZS 3000 the MEN connection between the neutral bar and the earth bar must be made at the main switchboard of the installation. This is the single point that links the installation neutral to the earthing system, completing the MEN earthing arrangement.
9Per AS/NZS 3000, what is the maximum rated residual current for an RCD relied upon for additional protection against electric shock?
A.10 mA
B.30 mA
C.100 mA
D.300 mA
Explanation: An RCD providing additional/personal protection against electric shock must have a rated residual current not exceeding 30 mA. AS/NZS 3000 requires 30 mA RCD protection on final subcircuits supplying socket-outlets and lighting in domestic installations.
10An RCD used for shock protection is deemed electrically unsafe under the Electricity (Safety) Regulations if, at five times its rated residual current, it fails to disconnect within how long?
A.40 milliseconds
B.300 milliseconds
C.1 second
D.5 seconds
Explanation: A 30 mA shock-protection RCD must interrupt all live conductors within 40 ms when passing 5 times its rated residual current, and within 300 ms at its rated residual current. Failing the 40 ms requirement at 5x renders it electrically unsafe.
