Description
Book SynopsisGuidance Note 2: Isolation & Switching provides clear guidance on what can be a confusing aspect of BS 7671. 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 incorporates changes from the first amendment, published in 2020, regarding Electric Vehicle Charging Installations to provide greater guidance on embracing changing technology within this sector. Additional changes within the second amendment include protection against thermal effects and fire caused by electrical equipment, protection against voltage disturbances and electromagnetic disturbances, and a new chapter on prosumer's low-voltage electrical installations covering energy efficiency measures, the interface with the smart grid, the management of electricity consumption, the management of renewable sources of electricity, and energy storage.
