Information
Definition
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.
Why it matters
It can improve resilience and protection discrimination but may increase installation complexity and cost. For UK users, it affects installation cost, available charging power, protective device selection and how easily a site can be expanded.
