_____________
1 Scope
Delete Note 5 and replace it by the following paragraph and new Note 5:
For RCCBs incorporated in, or intended only for association with socket-outlets, the
requirements of this standard may be used, as far as applicable, in conjunction with the
requirements of IEC 60884-1 or the national requirements of the country where the product is
placed on the market.
NOTE 5 RCCBs incorporated in, or intended only for association with socket-outlets, can either meet IEC 62640
or this standard.
2 Normative references
Delete the reference to IEC 60051.
Add to the existing list, the following new references:
IEC 60228:2004, Conductors of insulated cables
IEC 60664-3, Insulation coordination for equipment within low-voltage systems - Part 3: Use
of coating, potting or moulding for protection against pollution
Replace the reference to IEC 61543:1995 by the following new reference:

Amendment 1(2004)
Amendment 2 (2005)
4.10 According to the method of connection
In this subclause, replace the existing text and note by the following:
– RCCBs, the electrical connections of which are not associated with the mechanical
mounting;
– RCCBs, the electrical connections of which are associated with the mechanical mounting.
NOTE Examples of this type are:
– plug-in type;
– bolt-on type;
– screw-in type.
Some RCCBs may be of the plug-in type or bolt-on type on the line side only, the load terminals being usually
suitable for wiring connection.
Add the following new subclause:
4.11 According to the type of terminals:
– RCCBs with screw-type terminals for external copper conductors;
– RCCBs with screwless type terminals for external copper conductors;
NOTE 1 The requirements for RCCBs equipped with this type of terminals are given in Annex J.
– RCCBs with flat quick-connect terminals for external copper conductors;
NOTE 2 The requirements for RCCBs equipped with these types of terminals are given in Annex K.
– RCCBs with screw-type terminals for external aluminium conductors;
NOTE 3 The requirements for RCCBs equipped with these types of terminals are under consideration.
Table 1 – Limit values of break time and non-actuating time for alternating residual
currents (r.m.s values) for type AC and A RCCB
Replace, in this Table, the word “non-operating” by “non-actuating”.
Table 3 – Rated impulse withstand voltage as a function of the nominal voltage of the
installation
Replace, in Note 2, "see Table 15" by "see Table 22".
Replace, in table footnote a), "(see Tables 5 and 15)" by "(see Tables 5 and 22)".
6 Marking and other product information
Replace the contents of item k) by the following:
k) the position of use, if necessary;
Replace in the twelfth paragraph after Note 1, the word “circuit” by “conductor”
Add the following text at the end of Clause 6:
For universal terminals (for rigid-solid, rigid-stranded and flexible conductors):
– no marking.
– 4 – 61008-1 Amend.1 © IEC:2012
For non-universal terminals:
– terminals declared for rigid-solid conductors only shall be marked by the letters “s” or
"sol";
– terminals declared for rigid (solid and stranded) conductors only shall be marked by the
letter "r".
The markings should appear on the RCCB or, if the space available is not sufficient, on the
smallest package unit or in technical information.
8.1.3 Clearances and creepage distances (see Annex B)
Replace the existing text of this subclause by the following:
The minimum required clearances and creepage distances are given in Table 5 which is
based on the RCCB being designed for operating in an environment with pollution degree 2.
Compliance for item 1 in Table 5 is checked by measurement and by the test of 9.7.7.4.1 and
9.7.7.4.2. The test is carried out with samples not submitted to the humidity treatment
described in 9.7.1.
The clearances of items 2, 4 and 5 may be reduced provided that the measured clearances
are not shorter than the minimum allowed in IEC 60664-1 for homogenous field conditions.
In this case, after the humidity treatment described in 9.7.1, compliance for items 2, 4 and 5
and arrangements of 9.7.2 items b), c), d) and e) is checked in the following order:
– Tests according to 9.7.2 to 9.7.6 as applicable,
– Test according to 9.7.7.2 is applied with test voltages given in Table 16 with test
arrangements of 9.7.2 items b), c), d), e).
If measurement does not show any reduced clearance, test in 9.7.7.2 is not applied.
Compliance for item 3 in Table 5 is checked by measurement.
NOTE 1 All measurements required in 8.1.3 are carried out in Test sequence A on one sample and the tests of
9.7.7.2 are carried out before 9.7.1 on three samples of Test sequence B.
Parts of PCBs connected to the live parts protected against pollution by the use of a type 2
protection according to IEC 60664-3 are exempt from this verification.
The insulating materials are classified into material groups on the basis of their comparative
tracking index (CTI) according to 4.8.1 of IEC 60664-1:2007.
NOTE 2 Information on the requirements for design of solid insulation and appropriate testing is provided in
IEC 60664-1:2007, 5.3 and 6.1.3.
NOTE 3 For clearances on printed wiring material, the following Note 3 Table F.2 in 60664-1:2007 can be used:
“For printed wiring material, the values for pollution degree 1 apply except that the value shall not be less than
0,04 mm, as specified in Table F.4.” For creepage distances on printed wiring material, distances in Table F.4 in
60664-1:2007 can be used if protected with a coating meeting IEC 60664-3 requirements and tests.
NOTE 4 The dimensioning of clearances and creepage distances for spacings equal to or less than 2 mm for
printed wiring board may be optimised under certain conditions in case of use of IEC 60664-5. Only humidity levels
HL2 and HL3 are considered.
Table 5 – Minimum clearances and creepage distances
Delete, in this table, point 5 in the first column and the existing Note 3.
e
by the following text:
Replace, in this table, the last sentence of the existing footnote
61008-1 Amend.1 © IEC:2012 – 5 –
When interpolating, linear interpolation shall be used and values shall be rounded to the same number of digits as
the values picked up from the tables. For determination of creepage distances, see Annex B.
8.1.4.4
In the subclause, replace the existing text by the following:
Current-carrying parts including parts intended for protective conductors, if any, shall be
made of a metal having, under the conditions occurring in the equipment, mechanical
strength, electrical conductivity and resistance to corrosion adequate for their intended use.
Examples of suitable materials are given below:
– copper;
– an alloy containing at least 58 % copper for parts worked cold, or at least 50 % copper for
other parts;
– other metal or suitably coated metal, no less resistant to corrosion than copper and having
mechanical properties no less suitable.
Replace the existing note of this subclause by the following text:
In case of using ferrous alloys or suitably coated ferrous alloys, compliance to resistance to
corrosion is checked by a test of resistance to rusting (9.25).
This correction applies to the French text only.
8.1.5.1
Delete the second paragraph and the note in this subclause.
Replace the contents of the last paragraph by the following:
Compliance is checked by inspection, by the tests of 9.5 for screw-type terminals, by specific
tests for plug-in or bolt-on RCCBs included in the standard, or by the tests of Annex J, K or L,
as relevant for the type of connection.
8.1.5.2
Replace the existing text and Table 6 by the foll
