On-Site Guide (BS 7671:2018+A2:2022) (Electrical Regulations)

Product Information

These changes reflect requirements in European and international standards, as well as input from the Health & Safety Executive (HSE) and the Independent Review of Building Regulations and Fire Safety (2018).

IET and BSI publish Amendment 2 (2022) to BS 7671:2018 (IET

BS 7671:2018+A2:2022 is the most widely accepted way to demonstrate compliance with the applicable legislation, and so if you are an electrical professional, you need to ensure that you are working to the new changes introduced in the latest version of this standard. What’s new about BS 7671:2018+A2:2022?In medical locations of Group 1 and 2 Arc Fault Detection Devices (AFDDs) are not required to be installed. In medical locations of Group 0 Arc Fault Detection Devices (AFDDs) shall be used subject to a risk assessment. Precautions where particular risks of fire exist A collective PEI could, for example, be a group of single private houses, a group of flats in a building, or a group of small shops in a shopping centre with a common electrical power supply from one separate unit (generator/energy storage) producing energy and from the grid/supply network. Three operating modes are considered for collective PEIs. These are: There is a wide range of microgeneration technologies, including solar PV, wind turbines, small-scale hydro, and micro combined heat and power (CHP).

Collective PEIs are considered to be several consuming electrical installations connected to the same public distribution network and sharing one common set of local power supplies and energy storage equipment.A PEI is considered to be a low-voltage electrical installation connected (or not) to a public distribution network (the grid), able to operate with local power supplies (for example, PV panels or wind turbines), and/or with local storage units (for example, batteries). It monitors and controls the energy from the connected sources delivering it to current-using equipment (for example, motors, heating, lighting, and appliances such as washing machines, etc), and/or local storage units (for example, batteries), and/or the public distribution network. With active energy management, the end-user should be able to permanently monitor and control his or her own electricity consumption and production. The concept of the PEI has also been developed to take advantage of renewable sources of energy (such as solar photovoltaic (PV) and wind turbines) and energy storage. Regulation 422.1 (Precautions where particular risks of fire exist. General) now introduces requirements for the fire safety design of the building(s) to be documented. Regulation 422.2 (Conditions for evacuation in an emergency) introduces separate requirements for escape routes and a new concept of ‘protected escape routes’. Reference to conditions BD2, BD3, and BD4 have been deleted. Chapter 44 Protection against voltage disturbances and electromagnetic disturbances

BS 7671 and guidance - Institution of Engineering and Technology

BS 7671:2018+A2:2022 Requirements for Electrical Installations, IET Wiring Regulations 18th Edition (inc. changes from first amendment, published Feb 2022) All existing users of BS 7671 now need to adopt this latest version of the guidance to remain compliant with regulations and ensure the latest safety requirements are being met. Why use BS 7671:2018+A2:2022?This digital NICEIC Guide is intended for contractors who carry out electrical work in dwellings, including houses and flats. Regulation 443.4.1 now requires protection against transient overvoltages to be provided where the consequence caused by the overvoltage could result in:

BS 7671:2018+A2:2022 Requirements for Electrical

This NICEIC Guide is intended for contractors who carry out electrical installation work in dwellings, including houses and flats. The result is BS 7671:2018+A2:2022 - a modern standard that improves fire and end-user safety and increases sustainability. The previous version of this standard - BS 7671:2018+A1:2020 - is being withdrawn on 27 September 2022. All electrical installations must comply with BS 7671:2018+A2:2022 from 28 September 2022.Shared PEIs are considered to be, for example, where a number of individual houses group their interests and agree to share their supply with their neighbours from their own renewable power sources. Each house-owner may have installed private renewable energy power sources, which can either supply the private electrical installation or the group of private electrical installations. The three operating modes considered for shared PEIs are as for individual and collective PEIs above. PEIs and EEMS
