On-Site Guide (BS 7671:2008+A3:2015)

by The Institution of Engineering and Technology

Overview

Vital changes have been made in Amendment 3 regarding safety for contractors and consumers. This essential quick-reference guide to BS 7671 has been updated to the changes in Amendment 3 to BS 7671:2008.

The On-Site Guide is designed to be taken on-site for easy referencing and provides simple guidance on the application of BS 7671.

All updates in Amendment 3 will be included in the On-Site Guide, which include, but are not limited to:

• Consumer units (to come into effect January 2016)
• Wiring in escape routes
• Changes to earth fault loop impedances for all protective devices
• Circuit-breakers used as functional switches
• Overvoltages
• EMC & compatibility
• 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.
