Regulation Regulation 52 2. These include: All socket outlets not exceeding 20A, but with certain exceptions. One such exception would be permitted for a specific labelled or otherwise suitably identified socket outlet for connection of a particular piece of equipment.

All new electrical installations in the UK must comply with the latest version of the wiring regulations and as such if you are installing electrics on a regular basis it is an absolute must that you are up to date with the latest version.

Although the Wiring Regulations are non-statutory, they are referenced in several UK statutory documents and in most cases, for practical purposes, have legal force and can be used as defence in a court of law.

Absolutely anyone installing electrics should know their 17th edition wiring regulations. If you are looking for a job in the industry or looking to register as a domestic installer then you will need this qualification, however holding a 17th edition qualification does not in itself mean you are qualified to work as an electrician or register on a domestic installer scheme.

It is also important to note that the 17th Edition Wiring Regulations are also very useful for those working on the fringes of the electrical industry such as maintenance managers, engineers, project managers, architects and so on.

For them the course may be harder to pass due to some of the technical jargon but can be invaluable to complement existing skills and give them an understanding of what is needed for electrical installations in a variety of situations. Every so often we get a new incarnation of the wiring regulations which is why we have gone from the 1st to 17th Edition, however these are not amendments these are new editions.

Between editions we sometimes have changes and innovations like electric vehicle charging that warrant what is known as an Amendment. Since we have had the 17th Edition there have been 3 Amendments with the most recent coming into force on the 1st July Whilst it is generally a requirement that electricians and domestic installers hold a valid qualification in the latest IET Wiring Regulations Edition this is not true of the Amendments.

Having said that all installers are still required to install to the latest amendment. Usually when an Amendment is made a new book will be published and it is important that installers update themselves on the changes and hold the latest version of the book. Since the 17th Edition has been in force we have gone from a red to green and now to a yellow book. We have published an online tutorial for anyone looking to find the key changes between the Green and Yellow books here.

Update courses are only required when a new edition is published. This reduced the likelihood that an earth fault could occur before the RCD which due to the relatively high earth impedance, might never be cleared by upstream over current protection.

Since the 3rd amendment to the 17th edition has introduced a requirement that CUs be made from non combustible materials, many of the insulated CUs are no longer available and you may have to select a metal clad CU. In these cases it will be necessary to use enhanced insulation kits to protect the wiring before the RCD, and in effect bring it up to double insulated standards. Some circuits such as fridge freezer supplies , central heating and outside lights the list may include other circuits not listed here and will depend upon your installation and individual risk assessment may make for a better installation if they are not RCD protected.

These circuits can only be supplied by a non-RCD protected circuit if the installation rules mentioned at the begining of this article are met. The next best solution is to give these circuits an independent RCBO so that they are not affected by other circuits.
