Information
Definition
Rated voltage is the nominal voltage range for which a charger or component is designed to operate. It is normally assessed alongside phase availability, circuit capacity, protective devices, cable sizing and DNO/site constraints.
Why it matters
It helps confirm compatibility with UK single-phase and three-phase supplies and informs product selection and installation design. For UK users, it affects installation cost, available charging power, protective device selection and how easily a site can be expanded.
