Residual current operated circuit-breakers for household and similar use - Specific requirements for devices with screw-type terminals for external untreated aluminium conductors and with aluminium screw-type terminals for use with copper or…
1 Scope
This part of IEC 62873 applies to devices 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 – for use with untreated aluminium
conductors, or with screw-type terminals of aluminium material for use with copper
or aluminium conductors.
This document does not cover the use of aluminium conductors or aluminium terminals
for DC applications.
Flexible aluminium conductors are not covered by this document.
NOTE 1 Flexible aluminium conductors are under consideration.
This document cannot be used alone but it is intended to be applied together with
the applicable product standard.
In this document, copper-clad and nickel-clad aluminium conductors are considered
as aluminium conductors.
NOTE 2 In AT, AU and DE, the use of aluminium screw-type terminals for use with copper conductors
is not allowed.
— In AT and DE, terminals for aluminium conductors only are not allowed;
— In ES, the use of aluminium conductors is not allowed for final circuits in household
and similar installations e.g...
