These are real pages from the book. The table of contents is the full one: 8 parts and 61 topics.

The Problem Isn't You. It's How It Was Explained.

You're fitting a sub-board in a detached garage and you stop at the neutral and earth bars: link them, or keep them apart?

The manual covers it in clauses that point to other clauses. You read the MEN section, then the sub-mains section, and the answer is never in one place.

Main earthing conductor sized against the actives (AS/NZS 3000 Section 5 table)

In the book, that sub-board is one page: two separate bars drawn side by side, neutral running back on its own, earth running back on its own, and the only MEN link back at the main switchboard.

The same goes for the MEN system, RCDs, voltage drop, bathroom zones and safe isolation: each one has its own page.

You look, it makes sense, and you wire the board without going back to the manual.

COMPARE FOR YOURSELF

The Same Topic, Two Ways to Study It

THIS
  • The manual: line after line of clauses
  • MEN earthing explained only in words
  • You get to the job still unsure
In a multiple earthed neutral system, the neutral conductor of the supply is connected to earth at the source and at intervals along the distribution network, and the installation neutral is connected to the main earthing conductor by means of the MEN connection at the main switchboard, such that in the event of a fault between an active conductor and exposed conductive parts, fault current returns via the protective earthing conductor, the main earthing terminal and the MEN connection to the supply neutral, thereby permitting operation of the protective device within the required disconnection time.
FOR THIS
  • The MEN fault path in one drawing
  • The values and steps in a box
  • You see it and it makes sense

One Page, One Topic, All Clear

Think of it this way:

You've just finished a new circuit and the tester is in your hand. Which test comes first, where do the leads go, and what reading passes?

You open the book at insulation resistance and see the tester drawn on the circuit: actives and neutral to earth, 500 V d.c., and the 1 MΩ minimum in a box.

Vd = mV/A·m × I × L ÷ 1000 · worked: 10.8 V against an 11.5 V budget

The same with the MEN link, voltage drop, bathroom zones, RCDs and safe isolation: each one on its own page.

NZ Electrician: Wiring Rules Illustrated is 8 parts and 61 topics, all drawn, with the pass values on one page and the checklists at the end.

What you see drawn, you don't have to memorize.

Frequently Asked Questions

Is it for me if I've been on the tools for years?

Yes. It doesn't explain what a cable is: it goes straight to the regs, the paperwork, MEN earthing and the mandatory tests, laid out so you can revise them fast.

Where does the content come from?

From the Electricity (Safety) Regulations 2010, AS/NZS 3000:2018 with its NZ clauses, AS/NZS 3017, 3008.1.2, 3019 and 3760, NZECP 34, and the guidance published by WorkSafe NZ and the EWRB. It covers New Zealand only, not Australian state rules. Clauses are explained in our own drawings, not copied.

Is it official material?

No. It's independent study material. It isn't issued or endorsed by WorkSafe NZ, the EWRB or Standards New Zealand.

Does it replace the competence programme or my training?

No. It doesn't replace the standards, the regulations, your training or the competence programme, and it doesn't give you a certificate or count towards renewing your practising licence. It's there to help you revise before the programme and to check things on the job.

Are the practice questions the ones in the exam?

No. They're written for this book, in the style of the regulations exam, so you can check what you remember.

When and how does it arrive?

As a PDF by email, to the address you enter at checkout. The two bonus books come the same way.

Do I have to pay every month?

No. It's a one-off payment.

Can I have it on paper?

Yes, you can print it at home or at a print shop and keep it in the van.

How does the refund work?

You have 30 days. We refund everything if the file won't open, if the book isn't what you see on this page, if you were charged twice or if the email doesn't arrive: just email us.
