The Complete Guide to IET Regulations

05 January, 2015

ITE REGSRegardless of size, all data centres must comply with fundamental statutory electrical safety legislations. In order to meet these legislative requirements many safety managers turn to nationally recognised publications such as the IET Wiring Regulations. These are used to set standards for electrical installations in commercial and industrial premises. If you’re unsure what this means read on for an insider’s guide explaining what they are and answering commonly asked questions relating to the recognised guidelines. 

What are IET Wiring Regulations?

Officially known as IET Wiring Regulations BS 7671, these guidelines set the national standard for low voltage electrical installations. The group has been publishing UK regulations since 1882 and is renowned for its unmatched expertise and unfaltering compliance with IEC 60364 international standards. The guidelines are largely based on European Committee for Electrotechnical Standardisation documents which make them similar to the regulations followed by the majority of other European countries.

What purpose do they serve?

IET Wiring Regulations play a key role in enforcing electrical installation standards and safety measures. The regulations set benchmark standards for electrical installations in Great Britain as well as a number of other countries. Every few years the IET group co-publishes the IET Wiring Regulations BS 7671 in conjunction with the British Standards Institution (BSI).

Are they statutory requirements?

While the IET and BSI are not official government organisations they are nationally acknowledged groups. IET Wiring Regulations BS 7671 are also referenced in a number of UK statutory documents.

IET Wiring Regulations BS 7671 17th Edition

At present the most up to date version of the IET Wiring Regulations is the 17th Edition which was published in January 2008 and amended in 2011. It applies to all installations built after July 1 2008 and has brought the UK’s electrical shock prevention strategies up to date with those practiced by other European countries.

Where else are the guidelines used?

As well as setting national standards in the UK IET Wiring Regulations are used in Cyprus, Uganda, Mauritius, Sierra Leone, Sri Lanka, Trinidad and Tobago, St Lucia and a number of other countries across the globe.

Impending updates

In January 2015 the IET Wiring Regulations are set to undergo a major upgrade which will introduce Amendment No. 3:2015. This will affect all users and will greatly enhance the safety of both electrical installers and consumers.  

Complying with statutory rules is an essential part of the data centre build process. IET Wiring Regulations are designed to help contractors gain a thorough understanding of the legislative requirements and ensure that new data centre builds meet legal requirements.
