Guidance 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.
