Through its expertise in Standards and Knowledge, Assurance Services, Regulatory Services and Consulting Services, BSI helps clients to improve their performance, grow sustainably, manage risk and ultimately become more resilient. Extensive space for conferences, lectures, meetings and product launches spans four floors with additional outside space in a location easily accessible by rail, tube and river. Conditions for evacuation in an emergency) introduces separate requirements for escape routes and a new concept of ‘protected escape routes’.

For further information on the different RCD Types and the selection process, see IET Wiring Matters article (Issue 77 September 2019), ‘Which RCD Type?S Type time-delayed RCDs are not applicable for additional protection, hence, the operating times are not included in Regulation 643. As an accredited certification body, BSI Assurance cannot offer certification to clients where they have also received consultancy from another part of the BSI Group for the same management system. It is ideal for those working in specification, testing and inspection and for consulting engineers, as well as electrical installers and has been fully updated to BS 7671:2018:2022.

BS 7671:2018+A2:2022 Requirements for Electrical

In medical locations of Group 1 and 2 Arc Fault Detection Devices (AFDDs) are not required to be installed. Technical issues mentioned in this Chapter cover a whole range of safety issues, including protection against electric shock, system earthing, the selection of protective devices, isolation of the installation, protection against overcurrent, outage of the public network, and protection against transient overvoltages. Post-Brexit, this Amendment sees the further adoption of CENELEC Harmonized Documents as the UK continues the inclusion of standards for new and developing technologies. This means that the test instrument needs to be set to the Type AC RCD setting regardless of RCD Type.

NOTE: It is essential to liaise with the distribution network operator (DNO) when planning embedded generator installations. of BS 7671, supplied by a socket-outlet or pitch-outlet, which itself is required to be protected by an RCD with residual current rating not exceeding 30 mA by either Regulation 411.

The impact of Amendment 2 of the 18th edition (BS 7671:2018 The impact of Amendment 2 of the 18th edition (BS 7671:2018

There is a wide range of microgeneration technologies, including solar PV, wind turbines, small-scale hydro, and micro combined heat and power (CHP). When the instrument setting selected is for an AC Type RCD, the test current applied is a 50 Hz alternating current. If you think you may have a faulty RCD, firstly ensure there are no factors within the installation that are influencing the results.

The days of selecting an RCD according to current rating and rated residual current alone are gone, now the designer must select the RCD according to the nature of the residual fault currents, including pulsed or steady-state DC components expected to be present. Members of the committee responsible for the technical content of BS 7671, JPEL/64, are not permitted to release any further information before the publication date. A fundamental guidance book for all those involved with the testing and inspection of electrical installations. The IET and BSI are now urging all electrical professionals to ensure they become familiar with the changes. It is now a requirement (rather than a recommendation) to protect final circuits supplying socket-outlets and fixed current-using equipment with a rated current not exceeding 32 A by arc fault detection devices (AFDDs).

Protection against fire resulting from the electrical installation and the use of the electrical installation has been necessary ever since electricity was first introduced into buildings. 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.

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. Mark Coles, Head of Technical Regulations at the IET, said: “The IET is the authority for electrical installations in the UK and ensures that the National Wiring Regulations Committee carefully considers all necessary updates to the Regulations to ensure they best meet the needs of the industry.
