Vaults EV charger dedicated consumer units are recommended to ensure electrical safety, simplify future maintenance or upgrades, and comply with current wiring regulations. EV chargers typically draw high, continuous loads, and a dedicated consumer unit helps to isolate this load from the main circuits in the property, reducing the risk of overloading and minimising nuisance tripping of other circuits. It also allows for the inclusion of specific protection devices like tailored to EV charging needs, ensuring that the installation meets regulatory standards such as the IET Wiring Regulations (BS 7671).
