How has amina solved the requirement in NEK400 for earth fault protection of EV chargers?
The amina chargers must be installed behind a type A or B earth fault protector for protection against AC leakage current. DC leakage current is handled by the charger.
amina chargers comes with an Residual Direct Current Detecting Device (RDC-DD) according to the International Electrotechnical Commission’s (IEC) IEC62955 standard. This is a new standard that is specially adapted to electric vehicle (EV) chargers. DC protection is integrated into the charger. An electrician physically installs an earth fault circuit breaker Type A (or B) in the fuse box, in accordance with NEK-400.
