completely filling the casing, so that clearances and
creepage distances do not exist, if the component
passes the electric strength test in accordance with
the compliance clause below and in addition
• passes the tests and inspection criteria of 5.4.8
with an electric strength test of 1,5 kV multiplied by
1,6 (the electric strength test of 5.4.9 shall be
performed using 1,5 kV), and
• is subject to routine testing for electric strength
during manufacturing, using a test voltage of 1,5kV.
It is permitted to bridge this insulation with a
capacitor complying with EN 60384-14:2005,
subclass Y2.
A capacitor classified Y3 according to EN 60384-
14:2005, may bridge this insulation under the
following conditions:
• the insulation requirements are satisfied by having
a capacitor classified Y3 as defined by EN 60384-
14, which in addition to the Y3 testing, is tested
with an impulse test of 2,5 kV defined in 5.4.11;
• the additional testing shall be performed on all the
test specimens as described in EN 60384-14;
the impulse test of 2,5 kV is to be performed before
the endurance test in EN 60384-14, in the
sequence of tests as described in EN 60384-14.
5.5.2.1
Norway
After the 3rd paragraph the following is added:
Due to the IT power system used, capacitors are
required to be rated for the applicable line-to-line
voltage (230 V).

Finland, Norway and Sweden
To the end of the subclause the following is added:
Resistors used as basic safeguard or bridging
basic insulation in class I pluggable equipment
type A shall comply with G.10.1 and the test of
G.10.2.

5.6.1
Denmark
Add to the end of the subclause
Due to many existing installations where the
socket-outlets can be protected with fuses with
higher rating than the rating of the socket-outlets
the protection for pluggable equipment type A shall
be an integral part of the equipment.
Justification:
In Denmark an existing 13 A socket outlet can be
protected by a 20 A fuse.
