IEC 60998-2-3:2002 pdf download.Connecting devices for low-voltage circuitsfor household and similar purposes – Part 2-3: Particular requirements for connecting devicesas separate entities with insulation-piercingclamping units.
7.103 Classification according to conductor type
• IPCDs for rigid solid conductors only;
• IPCDs for rigid (solid or stranded) conductors only;
• IPCDs for flexible conductors only;
• IPCDs for rigid (solid and/or stranded) and flexible conductors.
7.104 Classification according to conductor insulation
• IPCDs for conductors according to IEC 60227;
• IPCDs for conductors according to IEC 60245:
• IPCDs for special conductors specified by the manufacturer.
7.105 Classification according to the number of cores in the conductor to be connected
• IPCDs for one core conductors:
• IPCDs for multicore cables or cords.
8 Marking
This clause of Part 1 is applicable except as follows:
Additional subclauses:
8.101 The following shall be indicated on the smallest package unit:
• if the IPCD is non-reusable or non-removable (7.101) (absence of marking indicates the IPCD is reusable);
• the connection and disconnection procedure, if necessary (for example, screw torque values if higher than stated in Table 102);
• the combinations of cross-sectional areas and types of conductors according to the classification of 7.103. 7.104 and 7105 for which the IPCD is designed (method of connection according to 7.102 if necessary).
The manufacturer shall describe the types of cable and of insulation suitable for his system if the contact pressure is being transmitted through this conductor insulation.
8.102 IPCDs classified according to 7.103 shall be marked as follows:
• terminals declared for solid conductors with the letter(s) s or sol;
• terminals declared for rigid conductors with the letter r;
• terminals declared for flexible conductors with the letter T.
• terminals declared for rigid (solid and/or stranded) and flexible conductors need not be marked.
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.
9 Protection against electric shock
This clause of Part 1 is applicable.
During the test a reusable IPCD shall not be damaged so as to impair its further use, for example. the breakage of screws or damage to the head slots, threads, washers, or stirrups.
The shape of the blade of the test screwdriver shall suit the head of the screw to be tested. The screws shall be tightened in one smooth and continuous application of the torque.
10.106 New IPCDs are fitted with new single-core conductors of the type and of the minimum and the maximum cross-sectional areas as declared by the manufacturer and are tested in the apparatus shown in Figure 101.
The test shall be carried out on 6 samples: 3 with the smallest conductor cross-sectional area and 3 with the largest conductor cross-sectional area.
The length of the test conductor shall be 75 mm longer than the height H specified in Table 103.
The test conductor is connected according to the manufacturer’s classification (7.102), in the clamping unit.
Clamping screws, if any, are tightened with the torque according to 10.105. Each conductor is subjected to the following test.
The end of the conductor is passed through an appropriate sized bushing in a platen positioned at a height H below the equipment as given in Table 103. The bushing is positioned in a horizontal plane, such that its centre line describes a circle of 75 mm diameter, concentric with the centre of the clamping unit in the horizontal plane. The platen is then rotated at a rate of approximately (10 ± 2) r/min.
The distance between the mouth of the clamping unit and the upper surface of the bushing shall be within 15 mm of the height in Table 103. The bushing may be lubricated to prevent binding, twisting or rotation of the insulated conductor. A mass, as specified in Table 103, is suspended from the end of the conductor. The duration of the test is 15 mm.
During the test, the conductor shall neither slip out of the clamping unit nor break near the clamping unit.
