cables other than those nominal cross-sectional areas appropriate to the rating of the
switch as given in Table 2, then the minimum and maximum size for which the anchorage
is provided may be marked in an area adjacent to the anchorage, e.g. “6 mm – 16 mm“ or

to one of the components parts of the switch,
- makeshift methods, such as tying the flexible cable in a knot or tying the ends with a
string, shall not be used,
- cord anchorage shall be suitable for the different types of flexible cables for which they
are intended.
Rewirable switches with earthing connection shall be designed with ample space for
slack of the earthing conductors in such a way that, if the strain relief should fail, the
connection of the earthing conductor is subjected to strain after the connection of current
carrying conductors and that, in the case of excessive stresses, the earthing conductor

Annex ZB
(normative)
Special national conditions
Special national condition: National characteristic or practice that cannot be changed over a
long period, e.g. climatic conditions, electrical earthing conditions. If it affects harmonization, it
forms part of the European Standard.

For the countries in which the relevant special national conditions apply these provisions are
normative, for other countries they are informative.

Clause Special national condition

7.7 Belgium, Finland, Germany, Netherlands, Norway and Sweden

Design B is not used due to installation practice.

8.1 United Kingdom
Add after the first paragraph:

The marking of the type reference is not used.

Germany
Add at the index n:
n) the symbol that electrotechnical expertise is required (see IEC 60417-6182) is to
be placed on the packaging.
8.3 United Kingdom
Add at the end:
The marking of the type reference is not used.

10.2 Norway
Add after the first paragraph:

Due to the lack of an earthing conductor in many existing old buildings, accessories
requiring earth connection cannot normally be used.

Clause Special national condition

10.3.3 Norway
Add after the first paragraph:

Due to the lack of an earthing conductor in many existing old buildings, accessories
requiring earth connection cannot normally be used.

10.5 Norway
Add after the second paragraph:

Due to the lack of an earthing conductor in many existing old buildings, accessories
requiring earth connection cannot normally be used.

12.2.5 Finland, Norway and Sweden

Add at the end:
The test shall be repeated with rigid solid conductors in the case they exist in the relevant
IEC standard, if the first test has been made with rigid stranded conductors.
In the case rigid stranded conductors do not exist, the test may be made with rigid solid
conductors only.
12.2.6 Finland, Norway and Sweden

Add the following paragraph at the end of the subclause:

An additional test with one rigid solid conductor and one rigid stranded conductor with the
same nominal cross-sectional area connected at the same time is required for terminals
allowing the connection of two conductors.

13.15.2 Denmark, Finland, Norway, Sweden and Switzerland

This subclause is mandatory.
Annex E Finland, Norway and Sweden

This annex is normative.
Annex ZC
(informative)
A-Deviations
A-Deviation: National deviations due to regulation, the alteration of which is for the time being outside
the competence of CENELEC member.

This European Standard falls under Directive 2014/35/EU.

NOTE (from CEN/CENELEC IR Part 2, 3.1.9): Where standards fall under EC Directives, it is the view
of the Commission of the European Communities (OJ No C 59; 1982-03-09) that the effect of the
decision of the Court of Justice in case 815/79 Cremonini/Vrankovich (European Court Reports 1980,
p.3583) is that compliance with A-deviations is no longer mandatory and that the free movement of the
products complying with such a standard should not be restricted except under the safeguard
procedure provided for the relevant Directive.

A-deviations in an EFT A-country are valid instead of the relevant provisions of the European
Standard in that country until they have been removed.

Clause Special national condition

11.2 Belgium (Reglement General sur les Installations Electriques, R.G.I.E. § 73.02).

Replace the second paragraph by:

They shall have a capacity not less than that of the corresponding terminals for the
supply conductors except that any additional external earthing terminal shall be of a size
suitable for conductors of at least 4 mm .

Annex ZZ
(informative)
Relationship between this European standard and the safety objectives of
Directive 2014/35/EU [2014 OJ L96] aimed to be covered
This European Standard has been prepared under a Commission’s standardization request relating to
harmonized standards in the field of the Low Voltage Directive, M/511, to provide one voluntary means
of conforming to safety objectives of Directive 2014/35/EU of the European Parliament and of the
Council of 26 February 2014 on the harmonization of the laws of the Member States relating to the
making available on the market of electrical equipment designed for use within certain voltage limits
[2014 OJ L96].
Once this standard is cited in the Official Journal of the European Union under that Directive,
compliance with the normative clauses of this standard given in Table ZZ.1 confers, within the limits of
the scope of this standard, a presumption of conformity with the corresponding safety objectives of
that Directive, and associated EFTA regulations.
