ExploreAbout this exam
The NSW electrical licence is the authorisation a person needs to carry out electrical wiring work in New South Wales, and SafeWork NSW is the state regulator that administers electrical licences and licence examinations. This independent study page is for candidates preparing for the licensing examination - typically electricians who have completed their trade training and are moving from supervised work to holding their own licence, plus overseas-trained or interstate practitioners who need to demonstrate current knowledge of NSW requirements. The exam samples the knowledge a licensed electrician is expected to apply on the job. Our practice material is organised into seven domains: electrical principles and theory; wiring systems and installation practices; electrical protection and earthing; electrical equipment and appliances; testing, verification and fault finding; work health and safety obligations; and the regulatory framework and licensing requirements. Preparation should be active rather than passive. Work through each domain, attempt questions before reading explanations, and keep a written log of the errors you make so you can revisit the underlying principle rather than memorising the answer. Because the retrieved SafeWork NSW pages returned "Page not found" content, no official examination parameters - question count, duration, pass mark, fee, retake rules or licence validity - could be confirmed for this page, and every such field is shown as unknown pending verification. Always confirm current requirements directly with SafeWork NSW before you book. This site is an independent study resource and is not affiliated with, endorsed by, or acting on behalf of SafeWork NSW or the NSW Government.
What you'll study
About NSW Electrical Licence preparation
How many questions are on the NSW electrical licence exam, and how long do I get?
We cannot state either figure. The SafeWork NSW pages retrieved for this page returned "Page not found" content, so the question count and time limit are unverified and recorded as unknown. Confirm both with SafeWork NSW directly before booking, and do not rely on figures from older forum posts or third-party summaries.
What pass mark do I need?
Unknown from the available source. No passing score could be sourced because the official examination page did not load. Treat any percentage you see quoted elsewhere as unverified until you have it in writing from SafeWork NSW. In practice, aim to be comfortably consistent across all seven domains rather than targeting a bare minimum.
How is the exam structured?
The format could not be confirmed from the retrieved source, so we do not state one. Candidates should check with SafeWork NSW whether the assessment is written, practical, or a combination, and whether any calculation or wiring-assessment components apply to their licence class. Prepare for both theory recall and applied fault-finding reasoning.
If I fail, how soon can I resit, and how many attempts do I get?
The retake policy is unverified - the source pages returned "Page not found", so no waiting period or attempt limit can be quoted. Ask SafeWork NSW about resit timing and any associated fees at the time you book. Do not assume a fixed cooling-off period based on what other candidates tell you.
How long is the licence valid once I have it?
The validity period could not be sourced and is recorded as unknown. Licence terms can change, so confirm the current duration and renewal process with SafeWork NSW rather than relying on memory or second-hand information. Diarise your renewal date as soon as the licence is issued so it does not lapse.
Which domain should I study first?
Start with electrical principles and theory, because voltage drop, load calculation, and protective device selection reasoning underpin the wiring, protection, and testing domains. Then move to protection and earthing, which is where many candidates lose marks. Leave regulatory and WHS content until last - it is largely recall-based and benefits from a fresh review close to the exam.
Where do candidates most often lose marks?
Common weak spots are earthing and protective device selection, interpreting test results against acceptable limits, and applying the correct regulatory requirement rather than a remembered habit. Another frequent problem is rushing calculation questions. Show your working, check units, and sanity-check whether an answer is physically plausible before committing to it.
Is this site run by SafeWork NSW?
No. This is an independent study resource and has no affiliation with, endorsement from, or connection to SafeWork NSW or the NSW Government. All practice questions are original material written for study purposes. For authoritative information on licensing, examinations, fees, and eligibility, go directly to SafeWork NSW.
What should I bring to the exam, and what does it cost?
Neither the fee nor the permitted materials could be confirmed, because the official pages did not load. Contact SafeWork NSW for the current fee, accepted identification, and any approved reference material or calculator rules. Never assume a calculator type or reference document is permitted until the regulator confirms it in writing.
