17.1 Explanation
A portable power distributor is intended for power supply at
different locations and often includes an RCD (residual current
protection device) and MCB (line safety switch).
The test procedures (19 and 20) available in the appliance tester
include the necessary test steps that apply to a large number of
commercially available power distributors.
Please note that the admissible limits and test steps of the test
procedures available in the appliance tester might be different from
the necessary limits and test steps of the switches used in the
power distributor (RCD, MCB,...).
For this reason, the specification, selection and order of the
individual tests must be determined by the responsible qualified
electrician.
The test socket is supplied with mains voltage.
The test sample must be disconnected from the power
supply network before starting the test.
Only portable power distributors may be tested.
If power distributors are firmly connected, there is a risk
of the appliance tester being destroyed.
Please observe the safety instructions of the respective
individual test.
Make sure that all plug connections are properly
connected to each other.
AUTO test no.

17.2 Application
The manufacturer recommends compliance with the following
points to test a portable power distributor:
1. option
2. option
Automatic test
The test procedures available
in the appliance tester can be
used.
Automatic test
The required individual tests
are different from the test
procedures available in the
appliance tester.
Procedure
Create a new test sample in
the database you are using.
(For questions regarding how
to create a test sample,
please refer to chapter 9.3.)
Create a customer-specific
test procedure in the
database you are using.
(For questions regarding how
to create a customer-specific
test procedure, please refer to
chapter 9.5.3.)
Assign the generally required
properties to the test sample
(ID no., designation,...).
Test standard:
VDE 0701/ 0702
Create a new test sample in
the database you are using.
(For questions regarding how
to create a test sample,
please refer to chapter 9.3.)
Select the test procedure
19 or 20 when creating the
test sample.
(The test procedure is
selected according to the
RCD characteristic of the
RCD (type A or type B) used
in the power distributor.)
Assign the generally required
properties to the test sample
(ID no., designation,...).
Test standard:
VDE 0701/ 0702
If necessary, adjust the limits
and the test times.
When creating the test
sample, select the customer-
specific test procedure you
created.
Carry out the automatic test
with the newly created test
sample.
If necessary, adjust the limits
and the test times.
Carry out the automatic test
with the newly created test
sample.
The automatic test of the portable power distributor has
been completed.
Alternatively, you can carry out all necessary individual tests using
the manual test according to VDE 0701/ 0702.
After the manual tests have been completed, you can assign the
results to an already existing or a newly created test sample.
Please refer to chapter 12, Manual testing according to VDE 0701-
0702 for further information.
