IEC 60998-2-1-2002 pdf download.Connecting devices for low-voltage circuits for household and similar purposes – Part 2-1: Particular requirements for connecting devices as separate entities with screw-type clamping units.
This clause of Part 1 is applicable except as follows:
Addition:
This standard applies to connecting devices with screw-type clamping units primarily suitable
for connecting unprepared conductors.
2 Normative references
This clause of Part 1 is applicable.
3 Definitions
This clause of Part 1 is applicable except as follows:
Additional definitions:
3.10 1 screw-type terminal
terminal for the connection of two or more conductors by means of screw-type clamping units
3.101 .1 pillar terminal
terminal in which the conductors are inserted into a hole or cavity, where they are clamped under the shank of a screw or screws. The clamping pressure may be applied directly by the shank of the screw or through an intermediate part to which pressure is applied by the shank of the screw
NOTE Examples of pillar terminals are given in FIgure 101.
3.101.2 screw terminal
terminal in which the conductors are clamped under the head of one or more screws. The clamping pressure may be applied directly by the head of a screw or through an intermediate part, such as a washer, a clamping plate or an anti-spread device
NOTE Examples of screw terminals are given in Figure 102.
3.1O1.3
stud terminal
terminal in which the conductors are clamped under a nut. The clamping pressure may be applied directly by a suitably shaped nut or through an intermediate part, such as a washer, clamping plate or an anti-spread device
NOTE Examples of stud terminals are given in Figure 102,
3.1O1.4
saddle terminal
terminal in which the conductors are clamped under a saddle by means of two or more screws or nuts
NOTE Examples of saddle terminals are given in Figure 103.
3,101.5
mantle terminal
terminal in which the conductors are clamped against the base of a slot in a threaded stud by means of a nut, by a suitably shaped washer placed under the nut, by a central peg if the nut is a cap nut, or by an equally effective means for transmitting the pressure from the nut to the conductors within the slot
NOTE Examples of mantle terminals are given in Figure 104.
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 BB.
5.4 Replacement of the first sentence by the following:
The necessary number of new samples to be submitted to the tests is divided into sets as detailed in annex BB and this standard is met if all tests are satisfied.IEC 60998-2-1 pdf download.
