The structure of the terminal shall ensure good electrical contact and a certain current carrying capacity, and its conductive metal parts shall have sufficient mechanical strength.
The connection of the terminal to the external conductor (wire) can be achieved with screws or other effective measures, but the contact pressure must be constant or little changed.
The structure of the terminal block should be designed to ensure that the wire is tightly pressed without damaging the wire and terminal block.
The position of the terminal shall be such that the heat dissipated by the appliance does not damage the insulation of the external connecting conductor.
The structure of the terminals shall be such that the connecting wires are not movable or do not create movements that are detrimental to the operation of the appliance or reduce the "insulation level" of a given installation category.
