The committee has decided that the contents of this amendment and the base publication will
remain unchanged until the stability date indicated on the IEC web site under
"http://webstore.iec.ch" in the data related to the specific publication. At this date, the
publication will be
• reconfirmed,
• withdrawn,
• replaced by a revised edition, or
• amended.
The contents of the corrigendum of January 2014 have been included in this copy.
_____________
4.11 According to the type of terminals
Replace Note 3 introduced by Amendment 1 by the following new Note 3:
NOTE 3 The requirements for RCCBs equipped with this type of terminals are given in Annex L.
8.1.3 Clearances and creepage distances (see Annex B)
Replace the third paragraph of this subclause, and the modifications brought to it by
Amendment 1, as follows:
The clearances of items 2 and 4 (except accessible surface after installation, see Note 1) may
be reduced provided that the measured clearances are not shorter than the minimum allowed
in IEC 60664-1 for homogenous field conditions.
Add the following new note after the third paragraph and renumber the existing notes of this
subclause, introduced by Amendment 1, accordingly:
NOTE 1 Accessible surface after installation means any surface accessible by the user when the RCD is installed
according to the manufacturer's instructions. The test finger can be applied to determine whether a surface is
accessible or not.
8.5 Operating characteristics
Replace "9.9 and 9.21" by "9.9.1, 9.9.2, 9.9.3 and 9.9.4"

8.15 Behaviour of RCCBs in case of earth fault currents comprising a d.c. component
Replace the second paragraph as follows:
Compliance is checked by the tests of 9.9.3.
Table 9 – List of type tests
In the table, delete the following item:
– Behaviour of RCCBs in case of an earth fault current comprising a d.c. component 9.21
9.7.2 Insulation resistance of the main circuit
Replace the existing text in item c) with the following text:
c) with the RCCB in the closed position, between all poles connected together and the frame
including a metal foil or part in contact with the outer surface of the housing of insulating
material but with the terminal areas kept completely free to avoid flashover between
terminals and the metal foil;
Replace 9.9 and the modifications brought to it by Amendment 1 by the following:
9.9 Verification of the operating characteristics
9.9.1 Test circuit and test procedure
The RCCB is installed as for normal use.
The test circuit shall be of negligible inductance. For tests according to 9.9.2, the test circuit
shall correspond to Figure 4. For tests according to 9.9.3, the test circuit shall correspond to
Figure 5 or Figure 6, as applicable.
The instruments for the measurement of the residual current shall display (or allow to
determine) the true r.m.s. value.
NOTE The information for instrument measurement is available at the following CTL webserver:

Unless otherwise specified, the tests are performed with no load at the reference temperature
of 20 °C ± 5 °C.
The RCCB shall perform the tests of 9.9.2, 9.9.3 and 9.9.4, as applicable. Each test is made
on one pole only, taken at random, with five measurements, unless otherwise specified.
For RCCBs having more than one rated frequency, the tests shall be carried out at the lowest
and highest frequency, except for test in 9.9.2.5, where verification is performed at only one
frequency.
For RCCBs having multiple settings of residual operating current, the tests shall be made for
each setting.
9.9.2 Tests for all RCCBs
9.9.2.1 Verification of correct operation in case of a steady increase of residual current
The test switches S and S and the RCCB being in the closed position, the residual current
1 2
is steadily increased, starting from a value not higher than 0,2 I , trying to attain the value of
∆n
I within 30 s, the tripping current being measured each time.
∆n
– 4 – 61008-1 Amend. 2 © IEC:2013
All five measured values shall be situated between I and I .
∆no ∆n
9.9.2.2 Verification of correct operation on closing on a residual current
The test circuit being calibrated at the rated value of the operating residual current I and the
∆n
test switches S and S being closed, the RCCB is closed on the circuit so as to simulate
1 2
service conditions as closely as possible. The break time is measured five times. No
measurement shall exceed the limiting value specified for I in Table 1, according to the type
∆n
of RCCB.
9.9.2.3 Verification of correct operation in case of sudden appearance of sinusoidal
a.c. residual current
a) All types
The test circuit being successively calibrated at each of the values of residual current
specified in Table 1, the test switch S and the RCCB being in the closed position, the test
voltage is suddenly established by closing the test switch S .
The RCCB shall trip during each test.
Five measurements of the break time are made at each value of residual current.
No value shall exceed the relevant specified limiting value given in Table 1.
b) Additional test for type S
The test circuit being successively calibrated at each of the values of residual current
specified in Table 1, the test switch S and the RCCB being in the closed position, the
residual current is suddenly established by closing the test switch S for periods
corresponding to the relevant minimum non-actuating times, with a tolerance of %.
−5
Each application of residual current shall be separated from the previous one by an
interval of at least 1 min.
The RCCB shall not trip during any of the tests.
9.9.2.4 Verification of correct operation in case of sudden appearance of residual
currents between 5 I and 500 A
∆n
The test circuit is calibrated at any two values of the residual current chosen at random within
the range 5 A to 200 A, among the following list 5 A, 10 A, 20 A, 50 A,
