11 Terminals
Replace title and the complete clause by the following:
11 Terminals and terminations
This clause of Part 1 is applicable except as follows:
11.2.1 Addition:
Screw type terminals may be identified by the terminal sizes given in the Table 107.
NOTE For screw type terminals not identified by terminal sizes given in the Table 107, Part 1 is applicable.
Screw type terminals identified by terminal sizes shall comply with standard sheets as
specified in 11.101 of this standard and are not subject to test as in 11.5 of Part 1.
Add the following new subclause:
11.101 Screw type terminals identified by terminal sizes
11.101.1 Terminals shall comply with the standard sheets as specified below, except those
for standard sheets 2-X, 2-XI and 2-XII. For these standard sheets, the length of thread in the
fixed part or nut and the length of thread on the screw or stud may be reduced, if the
mechanical strength of the terminal is adequate and at least two full threads of every
clamping screw are in engagement when a conductor of the most unfavourable cross-
sectional area is clamped.
Standard sheet 2-X applies to pillar terminals.
Standard sheet 2-XI applies to screw terminals and stud terminals.
Standard sheet 2-XII applies to saddle terminals.
Standard sheet 2-XIII applies to lug terminals.
Mantle terminals shall comply with standard sheet 2-X with regard to the dimensions D and e.
Terminals which are essentially of the pillar type, but with the part with the hole for the
conductor slotted to enable the conductor to be moved laterally into position, shall comply
with standard sheet 2-X. Anyhow, the maximum gap between the conductor restraining parts
on the side where the slot is located shall comply with standard sheet 2-XI.
If the required length of thread in a terminal screw hole is obtained by plunging, the edge of
the extrusion shall be reasonably smooth and the length of the thread shall exceed the
specified minimum value by at least 0,5 mm.
Compliance is checked by inspection, by measurement and, for terminals with a reduced
length of thread, by test of 11.101.2.
The maximum gap between the conductor restraining parts is checked by means of a steel
gauge pin with a diameter equal to e ± 0,05 mm.

60309-2 Amend. 1  IEC:2005 – 9 –
For terminals without pressure plate(s) or the like, complying with standard sheet 2-X, the
clamping screw is screwed fully home without a conductor in position. It shall not then be
possible to insert the gauge pin between the threaded part of the screw and the wall of the
conductor space.
For terminals complying with standard sheet 2-XI, and for terminals with a pressure plate or
the like complying with standard sheet 2-X, where it is not appropriate to insert the gauge pin
in all positions, a conductor is clamped in the terminal.
For terminals complying with standard sheet 2-X, the conductor is in the form of a rod with a
diameter equal to that corresponding to the middle cross-sectional area of the range specified
for the particular terminal, and having a flat end perpendicular to the axis.
For terminals complying with standard sheet 2-XI, the conductor is solid and has a diameter D
as specified in this standard sheet.
With this conductor in position, it shall not be possible to insert the gauge pin, applied in a
direction parallel to the axis of the conductor, into any gap through which a wire of a stranded
conductor might escape.
The minimum distance between the clamping screw and the end of the conductor, when fully
inserted, is specified in standard sheet 2-X. It is checked by means of the rod conductor
specified above, which shall pass into the conductor space for a distance, beyond the
threaded hole, at Ieast equal to the minimum distance specified.
For terminals with pressure plate(s) complying with standard sheet 2-X, the gauge pin is
applied to the gap between the pressure plate and the wall of the conductor space.
The following negative deviations from the specified values are allowed for the minimum
nominal thread diameter of the screw:
– 0,15 mm for screws with a nominal diameter not exceeding 5 mm;
– 0,22 mm for screws with a nominal diameter over 5 mm but not exceeding 10 mm;
– 0,27 mm for screws with a nominal diameter of over 10 mm.
This subclause does not exclude terminals of types other than those shown in the standard
sheets. Such terminals shall, however, comply with the other requirements of this clause as
far as is reasonable, and it may be necessary to
