Welcome to our Amendment 2 18th Edition section.

Find out more information on some of the changes in the latest amendment to the 18th Edition IET wiring regulations (BS 7671).

Each edition of the regulations is designed to improve safety levels in electrical installations and accommodate new technologies and equipment specifications from emerging trends. For example, EV charging, Type A RCDs, Prosumers installations etc.

Highlights from Amendment 2 include: - Mandatory use of Arc Fault Detection Devices for socket outlet circuits in certain residential premises - Transient over-voltage protection must be fitted in all installations, exceptions may be permitted where the owner opts out and accepts all consequences and losses - Extended use of RCBOs in residential premises to avoid unwanted tripping - A new chapter for Prosumers (those who produce their own electricity and consume from the grid) - Updates to Appendix 6 and Chapter 64 for certification and reporting

Designers, specifiers and installers need to see the full content of Amendment 2 to understand how the changes may affect their business. For example, Type AC RCDs now have limited permitted applications and should not be used on any circuit or equipment with any electronic components. It may be necessary to review designs and specifications in order to ensure full compliance.
