BS 7671
BS 7671 is the UK national standard for electrical installations, covering the design, erection, inspection, testing and verification of low-voltage electrical systems. Section 722 contains specific requirements for supplies to electric vehicles.
I
Individual Supply Per Outlet
Individual supply per outlet means each charging outlet has its own dedicated electrical supply or separately protected feed. It is normally assessed alongside phase availability, circuit capacity, protective devices, cable sizing and DNO/site constraints.
Installation Location
The physical environment where a charger is installed, such as indoor, outdoor, wall, pedestal, car park, depot or public space. It is normally checked against mounting method, exposure, durability, access requirements and the conditions at the installation location.
Installation Manual
An installation manual provides instructions for mounting, wiring, commissioning, configuration and safe installation of a charger. It is normally checked against mounting method, exposure, durability, access requirements and the conditions at the installation location.
Internal PE Breakage
Internal PE breakage refers to a charger design where the charger has a means of interrupting or isolating the protective earth path internally as part of its response to a detected PEN fault condition.
IT Earthing
IT earthing is an arrangement where the supply has no direct connection to earth or is connected through a high impedance. It is normally assessed during product selection, circuit design, installation verification and maintenance of EV charging equipment.
