WHY DO WE NEED THIS CODE OF PRACTICE?
WHY DO WE NEED THIS CODE OF PRACTICE?
ENABLES EV BUSINESS MODELS • Provides definitive guidance on safe electrical best practice • Enables confident procurement and compliance for insurers Transport Minister Norman Baker: “This is an excellent example of industry and Government working together to develop safe and practical solutions for plug-in vehicle recharging. This Code of Practice represents a real step forward in easing the path for consumers to make the switch to ultra-low emission vehicles.” Paul Everitt SMMT Chief Executive: “Electric vehicles can offer a practical and affordable ultra-low carbon driving option for many motorists and this new Code of Practice will ensure vehicle charging remains hassle-free and safe across the UK.”

Domestic installation principles PME earth PME earth Charging point –TT earth Building Conductive parts of separate earthing systems should not be simultaneously accessible A risk assessment needs to be conducted on site to determine particular requirements for each installation. If car cannot be charged inside the building then may not use the building’s PME earth – equipment needs to be on a TT earth outside OR equipment to disconnect supply could be fitted OR achieve electrical separation via an isolating transformer

Simplicity is key • All customer installations are different. A competent electrician should assess site requirements as part of sales package • As a minimum customers should be advised that BS 1363 socket outlets should be on separate, dedicated circuits • Simple ‘glove box’ advice on charging best practice should be provided with every car
