The IET introduces updated wiring standard for the industry

The Institution of Engineering and Technology (IET, formerly The IEE) has launched The IET Wiring Regulations, 17th Edition, BS 7671:2008 incorporating Amendment No.1, 2011. The amended IET Wiring Regulations set out the national standard for which all new electrical installations are to comply. The amended Wiring Regulations have been jointly published by the IET and the British Standards Institution (BSI) and feature important changes to the 17th Edition which was published in 2008.

One of the major changes in the amended Wiring Regulations is in Appendix 6 which introduces the new Electrical Installation Condition Report to replace the Periodic Inspection Report. This new reporting procedure has an easy to understand coding system and has been split into two areas: the first relating to domestic or similar installations up to 100 A and the second for larger installations, greater than 100 A.
In addition, the amended IET Wiring Regulations introduce a number of new sections relating to electromagnetic disturbances, devices for protection against overvoltage, medical locations and operating and maintenance gangways.
Geoff Cronshaw, Chief Electrical Engineer at the IET said:
"The amended Wiring Regulations, BS 7671:2008(2011) is based on CENELEC HDs and IEC standards, i.e. those of Europe and of the international community. The standardisation process is perpetual and standards are continually evolving requiring national standards bodies to incorporate the technical changes."
"It is therefore essential that all designers and electrical installers familiarise themselves with the amended IET Wiring Regulations to ensure that the work they do is compliant and, most importantly, is carried out in a safe and appropriate manner."
