18th Edition of BS7671 Wiring Regulations

Electacourse have been talking to Mark Coles of the IET talk about the 18th Edition of BS7671 Wiring Regulations.

When is the 18th Edition coming?

What we know so far about the 18th Edition Regulations is that the current anticipated publication date is July 2018, implementation date for installations to confirm to BS7671 18th Edition will be January 2019.

Electacourse have a number of offers to help our 17th Edition customers who are thinking whether to do the 17th Edition Course now or wait for the 18th Edition. See the chart below.

What changes are likely?

Protection against overvoltages

Clause 443 is likely to be significantly revised. BS7671 is dependent on International (IEC) and European (CENELEC – more about this below) standards. Both IEC and CENELEC have published major updates concerning overvoltage.

It is likely protection against transient overvoltage will be significantly changed in BS7671. Protection would have to be provided where the consequences affect human life, public services and commercial/industrial activity. And in line with the general trend of electricians being required to understand and exercise risk assessment, assessment will need to be made of whether protection is required in light of the potential human and commercial consequences of no protection.

Protection against fire

Chapter 42 concerns protection and precautions relating to fire caused by electrical equipment. It seems likely that BS7671:2018 will include regulations concerning the installation of arc fault detection devices – in response to the fact that RCDs cannot detect series or parallel arcing – faults which do not result in leakage current to earth.

Section 753

Section 753 will be extended to include embedded electrical heating systems for surface heating. This will include de-icing and frost prevention systems. Major revisions will include regulations relating to the protection against the effects of overheating caused by electrical short-circuits in embedded units and relating to harmful influence between the heating system and other electrical and non-electrical installations.

Energy efficiency

This major new section will cover several energy efficient areas, such as electric vehicles, lighting, metering, cable losses, transformer losses, power-factor correction, and harmonics

IEC and CENELEC

The wiring regulations BS7671 are decided upon by the UK committee JPEL/64, more information about the working of JPEL/64 can be found on the Wiring Matters blog.

JPEL/64 is informed by the UK’s commitment to the International Electrotechnical Committee (IEC) and the European Committee for Electrotechnical Standardization (CENELEC). The relationships between BS761, IEC and CENELEC are well explained by Mark Coles, the Technical Regulations Manager at the IET in his blog – Mark Coles blog.

IEC and CENELEC have their own update schedules. In addition to the likely BS7671 changes indicated above there will be many other smaller changes arising from these other standard bodies which will find their way in to the 18th Edition – these will be in addition to updates originating from JPEL/64’s consideration of electrical installation practice and requirements and the laws applicable in the UK.

What about Brexit and how will that change the 18th Edition schedule?

CENELEC is a European organisation and has a membership of 33 European states (ie more than just the EU states). The consequences of Brexit and the withdrawal of the UK from the European Union should not affect the UK membership of CENELEC. There is no indication at present that Brexit will change the anticipated publication schedule of the 18th Edition for July 2018.

What can you expect from Electacourse?

Electacourse are already a leading provider of courses for electricians and students aiming to achieve their 17th Edition qualification. Together with other industry leaders, Electacourse will participate in the public consultation for the 18th Edition of the IET Wiring Regulations and will have courses and student material available as soon as the details of the 18th Edition are finalised.

How to become an electrician in the UK

The electrical industry in the UK has recognised formal qualifications that provide a clear qualification route for an electrician whether or not they are a new entrant, already experienced or have overseas qualifications.

Introduction

Electacourse strongly recommend you contact electrotechnical industry bodies and organisations to confirm the qualifications required for becoming an electrician in the UK (link below) for the work which you plan to undertake, but the Electacourse summary understanding of the process of becoming qualified to work as an electrician in the UK is:

All people who are working unsupervised as a fully qualified electrician in the electrotechnical sector need to be qualified to the level of the industry-recognised NVQ level 3 qualifications. How you get to this level is dependent on your status.

For people who want to work only on domestic electrical installations, there is a lower threshold alternative of becoming registered on a self-certification scheme (run by Elecsa, Benchmark and others) who may be able to undertake and self-certify their work on domestic installations. See below the information about Part P and qualifying as a domestic installer.

Fully Qualified Electrician

To become a fully qualified electrician able to do industrial, commercial and not just domestic work, the following are the routes to qualification:

  1. For all new entrants to become recognised as an electrician, the Level 3 NVQ Diploma in Installing Electrotechnical systems and equipment (building structures and the environment) is required. This diploma can be obtained by undertaking study either with or without employer sponsorship at Further Education colleges or private training providers. By the nature of the practical requirement of some parts of electrical training, it is not possible to undertake all elements of this qualification by self-study alone.
  2. For individuals who have some previous experience whether in the UK or elsewhere, they need an interview with an assessor to develop an individual assessment plan without necessarily the need to go back to college to train in the classroom, (see AM2 on electricalqualifications.com).The AM2 assessment is administered by NET (http://netservices.org.uk/). We recommend that even if you have no electrical installation employment experience but have completed a college course, you seek advice from NET on final qualification requirements. AM2 is normally part of NVQ Diplomas.
  3. If you are already qualified in another country, then for some countries there are special arrangements where equivalence between electrical qualifications has been established, the following website has more information – http://summitskillsframework.naric.org.uk/index.asp?file=introduction

Domestic Electrical Installer

Domestic Installer Part P Courses available from some providers are designed to prepare candidates for the self-certification scheme Part P Assessment. On successful completion of a Part P Assessment, electricians are qualified to self-certify their own electrical work on domestic installations.

Electacourse Courses

Electacourse publish the 17th Edition Course provides everything required to achieve the 17th Edition Wiring Regulations qualification as assessed by the City & Guilds 2382-15 examination. This is an essential qualification for all UK electricians. It is also a general requirement (but not necessarily obligatory) for Domestic Installers. Optionally this course includes the City & Guilds 2382-15 17th Edition exam, we have partner examination centres throughout the UK.

Most of the other material which we publish at Electacourse is designed as preparation and revision material for the various City and Guilds examinations and are used by people who are taking these exams as part of their route to qualification and professional improvement as electricians.

We have courses and exam practice simulators which cover

On our website you will find links to our courses and to trade bodies and organisations which can provide complete information about becoming an electrician in the UK.  You may also find the information on http://www.electricalqualifications.com useful.  On this site you will also find information about transferring your home country qualifications to UK qualifications.
