5.6.4.2.1
Ireland and United Kingdom
After the indent for pluggable equipment type A,
the following is added:
– the protective current rating is taken to be 13
A, this being the largest rating of fuse used in the
mains plug.
N/A
5.6.5.1
To the second paragraph the following is added:
The range of conductor sizes of flexible cords to be
accepted by terminals for equipment with a rated
current over 10 A and up to and including 13 A is:
1,25 mm
2
to 1,5 mm
2
in cross-sectional area.
N/A
5.7.5
Denmark
To the end of the subclause the following is added:
The installation instruction shall be affixed to the
equipment if the protective conductor current
exceeds the limits of 3,5 mA a.c. or 10 mA d.c.
N/A
5.7.6.1
Norway and Sweden
To the end of the subclause the following is added:
The screen of the television distribution system is
normally not earthed at the entrance of the building
and there is normally no equipotential bonding
system within the building. Therefore the protective
earthing of the building installation needs to be
isolated from the screen of a cable distribution
system.
It is however accepted to provide the insulation
external to the equipment by an adapter or an
interconnection cable with galvanic isolator, which
may be provided by a retailer, for example.
The user manual shall then have the following or
similar information in Norwegian and Swedish
language respectively, depending on in what
country the equipment is intended to be used in:
“Apparatus connected to the protective earthing of
the building installation through the mains
connection or through other apparatus with a
connection to protective earthing – and to a
television distribution system using coaxial cable,
may in some circumstances create a fire hazard.
Connection to a television distribution system
therefore has to be provided through a device
providing electrical isolation below a certain
frequency range (galvanic isolator, see EN 60728-
11)”
NOTE In Norway, due to regulation for CATV-installations, and
in Sweden, a galvanic isolator shall provide electrical insulation
below 5 MHz. The insulation shall withstand a dielectric strength
