18th edition exam - my thoughts

[Tony Reidy]

There are other threads on the forum on the same subject. Calculators needed sometimes, not always.... each exam has different questions etc.

why are people still taking the exam if it came into force in January? How have you been able to work since jan without it?

You have about 2 years to take the 18th exam, but your work should be carried out to the 18th edition as from Jan19

What square roots are required?
All electricians should know the square roots of two and three as these are used in basic electrical calculations.

As Charlie says, adiabatic equation.
There are two types of question that arise.
One is work out the CPC size required for a protective device.
The other is to work out whether a protective device will operate within the prescribed times given specified conductor sizes.

Thought we already done this?
The 18th comes into force on the 1st of July.
Up until then, you can design to either the 17th, or the 18th.

As I've said previously, you should only need to tag the 7 sections and perhaps a couple of appendices or regularly used tables, purely for ease of going to the start of the section quickly. For the price of the book, it should come ready tagged, or at least flashed, like the On-site Guide sections are. For anyone tagging excessively, I'd question if they really understand their way navigating the book, which essentially is all any open book test is about.

Out of curiosity, there do you get the 2 years from?

The 18th was issued on 1st July 2018 and comes into effect on 1st January 2019, installations designed after 31st December 2018 are to comply with 18th.

In the exam you'll have 2 hours to answer 60 questions so that's 2 minutes per question.

To enable you to quickly find the information in the BBB, the tabs will save you critical time.

It's worth tagging, The sections, contents, index, definitions, abbreviations, parts, appendices and specific sections that may arise eg Max Disconnect Times, Min Insulation values etc.

Each to their own, I find 10 tags works for me and this method got me 59/60, with time to spare. Whilst it averages 2 minutes per question, I'd guess most people sitting the exam will find around 15 questions that take no more than 2 seconds to answer with no reference to the book required, leaving time for those questions that need more thought and referencing.

I thought that the 18th came into force January the 1st.
However, when I sat the 2391 earlier this month, there were no questions relating to any of the changes introduced in the 18th.
The reason given, is that the 18th doesn’t come into force until July 1st.

According to the regs the 18th came into effect on the 1st Jan 2019
