General safety requirements for residual current operated protective devices

IEC 60775:2017(E) provides general minimum requirements, recommendations and information for the drafting of standards on residual current operated protective devices (hereinafter referred to as residual current devices, "RCDs"). It applies to any device providing residual current protection intended primarily for protection against electric shock hazard.
This first edition cancels and replaces IEC TR 60755 published in 2008 and constitutes a technical revision.
This edition includes the following significant technical changes with respect to IEC TR 60755:
a. restructuration of the document, as a Group Safety Publication, in compliance with Guide 104;
b. introduction of classification for type F RCDs;
c. introduction of Clause 9 for tests of RCDs (operating characteristics, electrical endurance, behaviour in short-circuit conditions, trip-free mechanism, test device, surges, reliability, EMC).
It has the status of a group safety publication in accordance with IEC Guide 104.
