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). Except for single dwelling units, for all other cases where the consequences of an overvoltage of atmospheric origin are considered to be intolerable, a risk assessment has to be performed to determine if protection against transient overvoltages is required. This NICEIC Guide is intended for contractors who carry out electrical installation work in dwellings, including houses and flats. Arcs can be caused by insulation defects in cables, damage to cables by impact and penetration of nails and screws, loose terminal connections, and so on. An AFDD is designed to operate (trip) when a dangerous arc is detected by analysing the signature of the arc. Switching arcs caused by fluorescent lighting, for example, should not cause an AFDD to operate. AFDDs can be installed in distribution boards and consumer units to protect final circuits and should be installed in accordance with the manufacturer’s instructions. When installing components from a different manufacturer to that of the existing equipment in a distribution board or consumer unit, it is important to seek advice from the manufacturer that the new equipment is suitable and compatible. 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.

BS 7671:2018+A2:2022 Requirements for Electrical Installations, IET Wiring Regulations 18th Edition (inc. changes from first amendment, published Feb 2022) 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 The previous version of this standard - BS 7671:2018+A1:2020 - is being withdrawn on 27 September 2022.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. The 18th Edition Amendment 2 IET Wiring Regulations contains important new information for all electrical installers and engineers.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.

Calling all those involved with electrical installations, we’ve made major amendments to the key national standard on electrical installations. There is a wide range of microgeneration technologies, including solar PV, wind turbines, small-scale hydro, and micro combined heat and power (CHP).

The guidance is based on the requirements of BS 7671: 2018+A2:2022 Requirements for Electrical Installations, and references to Regulation numbers are to those contained in that Standard. Additional Details Author This NICEIC Guide is intended for contractors who carry out electrical installation work indwellings, including houses and flats. 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 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. Note: A new ‘foundation earthing’ requirement has been introduced into Chapter 54 to make arrangements for a suitable earth electrode provision for PEIs not connected to the LV public supply network.
