Residual current operated circuit-breakers for household and similar use – Part 3-1: Particular requirements for RCDs with screwless-type terminals for external copper conductors (Edition 1.0)
This part of IEC 62873 applies to RCDs equipped with screwless terminals@ for current not exceeding 20 A primarily suitable for connecting unprepared (see 3.5) copper conductors of cross-section up to 4 mm2. This part of IEC 62873 cannot be used alone but it is intended to be applied together with an RCD product standard (IEC 61008-1 or IEC 61009-1) if an RCD is equipped with screwless terminals. NOTE In AT@ CZ@ DK@ NL@ NO@ PO@ PT and CH@ the upper limit of current for use of screwless terminals is 16 A. In this part of IEC 62873@ screwless terminals are referred to as terminals and copper conductors are referred to as conductors
