General safety requirements for residual current operated protective devices
Allgemeine Sicherheitsanforderungen an Fehlerstrom-Schutzeinrichtungen
Overview
This document is a partial adoption of IEC 60755:2017 and contains basic minimum requirements, tests, recommendations, and information for the preparation of standards for residual current devices (hereinafter referred to as "RCDs"). It applies to any equipment containing a residual current operated assembly, function, or protective device as protection against the risk of electric shock. Residual current monitors (RCMs) in accordance with IEC 62020, whose purpose is to monitor an electrical installation and not to provide protection, are not covered by this document and are not considered similar or equivalent to RCDs. This document serves as guidance for the preparation of standards for residual current operated protective devices incorporated or implemented in other equipment.
