3.1O1.3
push-wire terminal
non-universal terminal in which the connection is made by pushing in rigid (solid or stranded) conductors
4 General
This clause of Part 1 is applicable.
5 General notes on tests
This clause of Part 1 is applicable except as follows:
5.3 Replacement:
The tests are carried out in the sequence listed for each set in Annex AA.
5.4 Replacement of the first sentence by the following:
The necessary number of new samples to be submitted to the tests are divided into sets as
detailed in Annex AA and this standard is met if all tests are satisfied.
6 Main characteristics
This clause of Part 1 is applicable.
7 Classification
This clause of Part 1 is apphcable except as follows:
Addition:
7.101 Classification according to the types of conductors which the terminal can accept
7.101.1 Universal terminal
7.101.2 Non-universal terminal
— terminals for solid conductors
— terminals for rigid conductors;
— terminals for flexible conductors.
8 Marking
This clause of Part 1 is applicable except as follows:
8.101 Addition:
Non-universal terminals classified according to 7.101 .2 shall be marked as follows:
— with the letter(s) “s” or “sol” for terminals declared for solid conductors;
— with the letter “r” for terminals declared for rigid conductors;
— with the letter “f” for terminals declared for flexible conductors.
This marking shall appear where it is practical on the end product or on the smallest package unit or in technical information and/or catalogues.
8.102 Addition:
An appropriate marking indicating the length of insulation to be removed before insertion of the conductor into the terminal shall be shown on the product or on the smallest package unit or in technical information and/or catalogues.
9 Protection against electric shock
This clause of Part I is applicable.
10 Connection of conductors
This clause of Part 1 is applicable except as follows:
Addition:
10.101 The connection or disconnection of conductors shall be made
— either by the use of a general purpose tool or a convenient device integral with the terminal to open it and to assist the insertion or the withdrawal of the conductors (for example, for universal terminals);
— or by simple insertion. For the disconnection of the conductors an operation other than a pull on the conductor only shall be necessary (for example, for push-wire terminals).
10.102 Terminals shall accept two or more conductors of the same or of different nominal cross-sectional areas or compositions if applicable.
Universal terminals shall accept rigid (solid or stranded) and flexible unprepared conductors. Non-universal terminals shall accept the types of conductors declared by the manufacturer.
The relationship between the rated connecting capacity of clamping units and connectable conductors as well as data on diameters of conductors are given in Table 101.
10.104 Compliance with the requirements of 10.101 to 10.103 shall be checked by inspection, and by the following tests:
10.104.1 The test is carried out on three new terminals with copper conductors of the type and the cross-sectional area, in accordance with Table 101, having the smallest and then the largest diameter conductor being connected to each clamping unit.
This connection and subsequent disconnection shall be made 5 times with the smallest diameter conductor and 5 times with the largest diameter conductor.
New conductors shall be used each time, except for the 5th time, when the conductor used for the 4th insertion is 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 these tests, the terminal shall not be damaged in such a way as to impair its further use.
1O.104.2 Three new terminals are fitted with new conductors of the type and of the cross- sectional area according to Table 101. Before insertion into the terminal, wires of stranded rigid conductors and flexible conductors shall be reshaped.
It shall be possible to fit the conductor into the terminal without undue force in the case of universal terminals and with the force necessary by hand in the case of push-wire terminals.
The conductor is either pushed as far as possible into the terminal or has to be inserted so that adequate connection is obvious.
After the test, no wire of the conductor shall have escaped outside the terminal.
Addition:
10.105 Three new clamping units are fitted with new conductors of number, cross-sectional area and type (flexible and/or rigid stranded) specified by the manufacturer in the equipment shown in Figure 101.
The following tests shall be carried out using new samples for each of the following:
a) the conductors of the smallest cross-sectional area;
b) the conductors of the largest cross-sectional area.
The length of the test conductor shall be 75 mm longer than the height H specified in Table 102.
The test conductor is then connected in the clamping unit in the in tended manner.
