BS IEC 62873-3-3:2016

What is BS IEC 62873-3-3 ‒ Residual-current devices about?

BS IEC 62873-3-3 is the third part of an international multi-series standard that outlines the requirements for residual current devices. BS IEC 62873-3-3 provides the specific requirements for the RCDs with screw-type terminals for external untreated aluminium conductors and with aluminium screw-type terminals for use with copper or with aluminium conductors. BS IEC 62873-3-3 applies to RCDs equipped with screw-type terminals of copper or of alloys containing at least 58 % of copper (if worked cold) or at least 50 % of copper (if worked otherwise), or of other metal or suitably coated metal, no less resistant to corrosion than copper and having mechanical properties no less suitable. BS IEC 62873-3-3 specifies requirements like terms, definitions, classification, characteristics of RCDs, marking and other product information, standard conditions for operation in service and for installation, requirements for construction and operation, tests, etc.
