After much expectation, Amendment 2 to BS 7671:2018 has now come into effect, and introduces amongst a number of other things, new requirements for Arc Fault Detection Devices (AFDDs), updated requirements for the fire safety design for buildings, and a new chapter on Prosumer’s Low Voltage Electrical Installations. Amendment 2 was issued on 28th March 2022 and may be implemented immediately, with the previous version, BS 7671:2018+A1:2020, remaining current but being withdrawn on 27th September 2022.
This update to the IET Wiring Regulations forms the national standard to which all new electrical installations and additions, and alterations to existing electrical installations in the UK are to comply.
The changes include, but are not limited to:
- a new requirement for Arc Fault Detection Devices (AFDDs) in some AC final circuits for installations in some types of higher risk residential buildings;
- updated requirements for the fire safety design for buildings;
- the method for determining the requirement to provide overvoltage protection (SPDs);
- changes to identification, labels and notices, such as for consumer units, affecting how safety related information is provided to the user of an electrical installation;
- a new chapter on Prosumer’s Low Voltage Electrical Installations.
