Special national conditions
Special national condition: National characteristic or practice that cannot be changed even over a long
period, e.g. climatic conditions, electrical earthing conditions.
NOTE If it affects harmonization, it forms part of the Harmonization Document.
For the countries in which the relevant special national conditions apply these provisions are normative,
for other countries they are informative.
Country Clause Special national condition
In Norway the following additional requirements apply:
Norway 523.1
Special requirement may apply in Norway due to national building practice and
the extended use of insulation materials in building walls.
Germany
521.11 In Germany additional requirements apply (see annex to German Special
National Condition on Clause 521.x)
In Germany the following additional requirements apply:
521.12
"521.x Inherently short-circuit proof and inherently earth-fault-proof wiring
Where protective devices for the protection in case of short-circuit in
accordance with 473.2.2.1 of IEC 60364 are not used, cables and conductors
shall be laid inherently short-circuit proof and inherently earth-fault-proof.
The following types of wiring are regarded as inherently short-circuit proof and
inherently earth-fault proof:
a) Conductor arrangements where contact between the conductors and contact
with earthed parts are prevented and where no short-circuit is to be expected
due to external influences (e.g. falling parts);
b) Arrangement consisting of single-core cables, e.g. in accordance with
IEC 60502, single-core non-metallic -sheathed cables in accordance with
IEC 60227-4 or single-core rubber-insulated and sheathed flexible cables in
accordance with IEC 60245-4;
c) Cables and rubber-insulated and sheathed flexible cables laid so that they
are accessible but not in the vicinity of combustible materials and where the
risk of mechanical damage is prevented.
d) Conductor arrangement consisting of single-core non-sheathed cables of
suitable type of construction (e.g. special rubber-insulated cables in
1)
accordance with IEC 60XXX , rated voltage U /U at least 1,8/3 kV or
equivalent).
An arrangement of cables and insulated conductors which could burn out
without endangering their environment (e.g. cables in ground) is considered as
equivalent to inherently short-circuit proof and inherently earth-fault-proof wiring
with regard to safety."

Country Clause Special national condition
521.13 In Germany the following additional requirements apply:
"521.13 Accessories
Boxes and enclosures for accessories, e.g. connecting boxes for housing
terminals, socket-outlets or switches shall comply with the requirements of
EN 60670.
Boxes and enclosures intended to be installed in concrete or in hollow walls,
shall have the following markings according to EN 60670-1 on the boxes and
enclosures or provided by the manufacturer on the smallest package unit or in
the instructions of the manufacturer
- for use in concrete: symbol 90 °C;
- for use in hollow walls: symbol H.
GP-enclosures according to EN 60670-24 (under preparation) are not allowed
to be installed in Germany.
Socket outlet-systems which accept the simultaneous connection of more than
one plug in the interface of one socket outlet are not allowed in Germany.
521.6 In Germany and the Netherlands in the case of basic-insulated conductors in
conduit systems, cable trunking systems and cable ducting systems, only the
conductors of one main circuit, including the auxiliary circuits associated with
this main circuit, may be laid in conduit or in single-channel trunking or in one
duct of a multi-channel trunking, except in electrical and enclosed operating
areas. The uncut conductors of several circuits may, however, be fed through
common through-run boxes.
