is DC residual current protection required ?


I have a question regarding the use RCD type Bs and residual current detectors.

From what i have read online, it seems that EVSE stations require some sort of protection against DC fault currents. This can either be implemented with a type B rcd or a circuit that detects DC currents of 6mA or higher. From what i have read this requirement is stated in the IEC 61851 standard.

Could an expert on this topic perhaps help me clarify if this is also a requirement for single phase AC chargers or just 3 phase AC chargers? Is this an international requirement or just in the EU? I do not have access to these standards and would rather get an answer from someone with experiance on this topic anyways.

Thank you for your time.

DC residual current protection is required in the EU for both single and 3 phase.
