Question to the Department for Transport:

To ask His Majesty's Government what assessment they have made of the risk of protective earthed neutral faults in public and street chargers for electric vehicles.

Safety requirements relating to protective earthed neutral faults, including those for electric vehicle (EV) chargepoints, are covered by The Electricity Safety, Quality and Continuity Regulations 2002, BS 7671 Requirements for Electrical Installations, the Institution of Engineering and Technology's code of practice for EV Charging Equipment, and the Energy Networks Association’s Engineering Recommendation G12. The Government has not undertaken any separate risk assessment of protective earthed neutral faults in EV chargepoints.
