24.7 Conductors of supply cords shall not be consolidated by lead-tin soldering where they are subject to
contact pressure, unless the clamping means is so designed that there is no risk of a bad contact due to
cold flow of the solder.
Compliance is checked by inspection.
The requirement may be met by using spring terminals. Securing the clamping screws alone is not
considered adequate.
24.8 For all types of attachment, moulding together the supply cord to the enclosure or part of it shall not
affect the insulation of the cord.
Compliance is checked by inspection.
24.9 Inlet openings shall be provided with a bushing, or shall be so constructed that the protective
covering of the supply cord can be introduced without risk of damage.
Compliance is checked by inspection and by manual test.
24.10 Inlet bushings shall:
– be so shaped as to prevent damage to the supply cord;
– be reliably fixed;
– not be removable without the aid of a tool.
Compliance is checked by inspection and by manual test.
24.11 At inlet openings, the insulation between the conductor of a supply cord and the enclosure of the
tool, if of metal, shall consist of the insulation of the conductor and, in addition, of at least two separate
insulations.
A separate insulation shall consist of:
– the sheath of a supply cord at least equivalent to that of a cord complying with IEC 60227 or
IEC 60245; or
– a lining or bushing of insulating material complying with the requirements for supplementary
insulation.
Compliance is checked by inspection.
