This Code of Practice, published January 2012, aims to provide expert guidance on EV charging equipment installation, an important emerging area which is not covered in detail by the current edition of the Wiring Regulations (BS 7671) or the IET’s Guidance Notes.
Aimed at experienced electricians interested in understanding a wide range of equipment and systems available, it covers the specialised installation requirements of electric vehicle charging equipment in public, private and commercial locations.
The Code of Practice provides detailed on-site guidance and recommendations on all aspects of the installation from the origin of the electrical supply, through distribution and final circuits, installation of the charging equipment itself to the cable between the charging equipment and vehicle's electrical inlet. Also included are related issues of site layout and planning and subsequent inspection, testing, certification and maintenance of installations.
Exclusive guidance on latest electrical requirements
The Code of Practice includes an overview of all types of equipment, connectors and cables that an installer is likely to encounter and provides detailed references to all relevant standards and regulatory requirements in the UK – including, in Section 5, the latest guidance based on advice from the HSE on:
- When to use TT earthing
- Special precautions for connecting to TN-C-S (PME supplies)
- The use of electrical separation, isolating transformers and RCDs
- The need for a separate, dedicated electrical circuit for EV charging.
