The IET Wiring Regulations are of interest to all those concerned with the design, installation and maintenance of electric wiring in buildings. The market includes electricians, electrical contractors, consultants, local authorities, surveyors and architects. This book will also be of interest to professional engineers, as well as students at university and further education colleges. All users of the IET Wiring Regulations need to be aware of the coming changes in Amendment 3 to the 17th Edition (BS 7671:2008+A3:2015). Potentially life-saving changes make this a vital update. These changes include (but are not limited to) amendments in the following areas: * Consumer units (to come into effect January 2016) * Wiring in escape routes * Changes to earth fault loop impedances for all protective devices * Updated EIC and EICR forms * Changes to definitions throughout the Regulations Amendment 3 published on 5 January 2015 and comes into effect on 1 July 2015. All new installations from this point must comply with Amendment 3 to BS 7671:2008.
