11 Terminals and terminations
Replace Clause 11 (including tables) by the following:
11 Terminals and terminations
11.1 Terminals for unprepared copper conductors
11.1.1 Common requirements
11.1.1.1 Terminals shall be such that connection is made by means of screws, nuts, springs,
wedges, eccentrics, cones or equally effective means or methods, but without requiring a
special-purpose tool for connection or disconnection.
Compliance is checked by inspection.
11.1.1.2 Terminals shall be fixed in such a way that they will not work loose when the
clamping means are tightened or loosened.
This requirement does not preclude floating terminals or terminals mounted on floating
elements, such as those used in some stack-type switches, provided their movement does not
impair the correct operation of the switch.
Compliance is checked by fastening and loosening 10 times a conductor having the maximum
or declared cross-sectional area specified in Table 4, for screw-type terminals the torque
applied being the torque specified in Table 20.
11.1.1.3 Terminals shall be designed or placed so that a conductor cannot slip out while
being connected or while the switch is being operated as intended.
Compliance is checked by the following tests:
a) terminals are fitted with conductors of maximum or declared cross-sectional areas
according to Table 4 and screw type terminals are tightened with the torque according to
Table 20. The test is repeated with the terminal fitted with conductors of minimum cross-
sectional area according to Table 4;
b) for terminals intended for the connection of two or more conductors, the test is repeated
with the terminal fitted with the declared numbers of conductors;
c) before insertion into the terminal, wires of rigid conductors are straightened and flexible
conductors are twisted in one direction, so that a uniform twist of one complete turn in a
length of approximately 2 cm is obtained;
d) the conductor is inserted into the terminal over a length equal to the minimum distance
prescribed or, if no distance is prescribed, until an end-stop is reached or until the
conductor just projects from the far side of the terminal and in the position most likely to
assist a strand to escape;
e) for flexible conductors the test is repeated using a new conductor which is twisted as
prescribed above, but in the opposite direction.
After the test, the conductor shall not have escaped into or through the gap between the
clamping means and retaining device.

Table 5 – (Void)
11.1.1.4 Terminals suitable for the connection of flexible conductors shall be located or
shielded so that, if a wire of a flexible conductor escapes from a terminal when the conductors
are fitted, there is no risk of contact between live parts and accessible metal parts, and, for
switches for Class II appliances, between live parts and metal parts separated from
accessible metal parts by supplementary insulation only.
Furthermore, there shall be no risk of short-circuiting those terminals which are electrically
connected together by switch action.
Compliance is checked by inspection and by the following test:
a) at the end of a flexible conductor having the minimum or declared cross-sectional area
specified in Table 4, the insulation is removed for a length of 8 mm. One wire of the
flexible conductor is left free and the remainder are fully inserted into the terminal and
clamped;
b) the free wire is bent, without tearing the insulation back, in every possible direction, but
without making sharp bends around barriers.
61058-1 Amend. 2 © IEC:2007 – 13 –
The free wire of the flexible conductor shall not touch the relevant parts mentioned above.
Furthermore, the free wire of a flexible conductor connected to an earthing terminal shall not
touch any live part.
11.1.1.5 Terminals shall be designed so that they clamp the conductor without undue
damage to the conductor.
Compliance is checked by inspection.
NOTE A test is under consideration.
11.1.1.6 Terminals shall be designed so that the end of a conductor introduced into the hole
is visible or that the insertion of the conductor is prevented by a stop if further insertion may
reduce creepage distances and/or clearances or influence the mechanism of the switch.
Compliance is checked by inspection and during the tests of 11.1.1.3 and 11.1.1.4.
11.1.2 Screw-type terminals for unprepared conductors
11.1.2.1 Screw-type terminals shall allow the connection of conductors having cross-
sectional areas and wire type as specified in Table 4.
For terminals classified according to 7.2.1, the full clamping range for flexible conductors and
rigid conductors must be met.
For terminals classified according to 7.2.2, the values must be met for the cross-sectional
area and wire type as declared.
NOTE Examples of screw-type terminals are given in Figures 1, 2, 3, 4 and 5.
Compliance is checked by inspection, by measurement and by insertion of flexible and rigid or
declared conductors of cross-sectional areas according to Table 4.
The conductors shall be able to enter into the terminal aperture without undue force to the
designed depth of the terminal.
11.1.2.2 Screw-type terminals shall be designed so that they clamp the conductor reliably
and between metal surfaces.
Compliance is checked by inspection and by the following test.
a) The screw-type terminals are fitted with conductors of the smallest and largest or declared
cross-sectional areas specified in Table 4, the terminal screws being tightened with a

11.1.2.3 Screws and nuts for clamping the conductors shall not serve to fix any other part,
although they may hold the clamping part in place or prevent it from turning.
Compliance is checked by inspection and during the tests of 19.2.
11.1.3 Screwless terminals for unprepared conductors
11.1.3.1 Screwless terminals shall allow, according to their classification, the proper
connection of conductors having cross-sectional areas as specified in Table 4 up to and
including 2,5 mm of cross-sectional area for flexible conductors, and up to and including
4 mm for rigid conductors.
It shall be obvious how the insertion and disconnection of the conductors are intended to be
effected.
NOTE Examples of screwless terminals are shown in Figure 6.
The intended disconnection of a conductor shall require an operation, other than a pull at the
conductor, such that it can be effected manually with or without the help of a tool in normal
use.
Openings for the use of a tool intended to assist the insertion or disconnection shall be clearly
distinguishable from the opening for the conductor.
Compliance is checked by inspection, by measurement and by insertion of the appropriate
flexible and/or rigid conductors of cross-sectional areas according to Table 4.
The conductors shall be able to enter without undue force into the terminal aperture to the
designed depth of the terminal.
11.1.3.2 Screwless terminals shall withstand the mechanical stress occurring in normal use.
The conductor shall be clamped reliably and between metal surfaces, except that, for
screwless terminals intended to be used in circuits carrying a current not exceeding 0,2 A,
one of the surfaces may be non-metallic.
Compliance is checked by the following test, which is carried out with uninsulated copper
conductors, at first having the largest or declared cross-sectional area, and then having the
smallest or declared cross-sectional area specified in Table 4:
a) either rigid: five insertions and disconnections for solid conductors and one insertion and
disconnection for stranded conductors;
b) or flexible: five insertions and disconnections;
c) or rigid and flexible: if the terminal can accept both types of conductors, the tests are
carried out with rigid and flexible conductors for the number of times indicated above.
The conductors are inserted and disconnected for the number of times indicated above using
new conductors each time, except for the last time, when the conductors used for the last but
one insertion are clamped at the same place. For each insertion, the conductors are either
pushed as far as possible into the terminal or shall be inserted so that adequate connection is
obvious.
After each insertion, the conductor is twisted through 90° in an axial direction and then
subjected to a pull of the force as specified in Table 6; the pull is applied without jerks, for
1 min, in the direction of the axis of the conductor space.
If the terminal is declared as suitable for two or more conductors, the appropriate pull is
applied consecutively to each conductor.
During the application of the pull, the conductor shall not come out of the terminal.
61058-1 Amend. 2 © IEC:2007 – 15 –
After these tests, neither the screwless terminals nor the clamping means shall have worked
loose.
NOTE A bending test for rigid conductors is under consideration.
11.1.3.3 Screwless terminals intended to be used for the interconnection of more than one
conductor shall be designed so that
– after the insertion, the operation of the clamping means of one of the conductors is
independent of the operation of the clamping means of the other conductor;
– during the disconnection, the conductors can be disconnected either simultaneously or
separately.
Compliance is checked by inspection and by tests with the appropriate conductors in any
combination.
11.1.3.4 Screwless terminals shall withstand the thermal stress occurring in normal use.
When the screwless terminal does form part of a conductive path through the switch, which
includes the switching device of the switch, compliance is checked during the tests of
Clause 17.
When the switch has a rated number of operating cycles below 10 000, or when the screwless
terminal forms part of a conductive path through the switch, which does not include the
switching device of the switch, compliance is checked by the following thermal endurance
test.
For the purpose of this test for switches classified according to 7.1.3.2 and 7.1.3.3, three
separate new switches are mounted and connected as declared and are placed in a heating
cabinet which is initially kept at a temperature of 25 °C ± 2 °C.
Switches classified according to 7.1.3.3 are mounted as in normal use.
For switches classified according to 7.1.3.1, three separate new switches are kept at
25 °C ± 10 °C throughout this test and only submitted to the current cycles.
During the test, the maximum rated current is passed through the switches.
Then the switches are subjected to 192 test cycles, each cycle having a duration of
approximately 1 h, as follows:
a) the temperature in the cabinet is raised in approximately 20 min to the maximum ambient
temperature. It is maintained within ± 5 °C of this value for approximately 10 min;
b) the switches are then allowed to cool down in approximately 20 min to a temperature of
approximately 30 °C, forced air cooling being allowed. They are kept at this temperature
for approximately 10 min. During the cooling-down period, no current is flowing through
the specimens;
c) the temperature in the heating cabinet shall be measured at a distance of at least 50 mm
from the specimen assemblies.
After the 192 test cycles, the temperature rise at the screwless terminals shall not exceed
55 K when measured in accordance with 16.2.2 except that the temperature-rise test at the
screwless terminals is carried out at rated current and in an ambient temperature of
25 °C ± 10 °C.
If one of the screwless terminals does not comply with the test, the test is repeated using a
second set of specimens all of which shall then comply.
