For cables suitable for trailing
– Cables suitable for trailing have a higher thermal loading capacity.
– Thus the above−named standards allow for higher currents.
– Therefore it may occur that a smaller cross−section is permitted for cables suitable
for trailing than for the corresponding fixedly installed cable.
For long motor cables
– In particular in dynamic applications, depending on the cable length, you may
have to take the voltage drop on the cable into consideration.
– In these cases you must select a greater cable cross−section.
For motors with terminal boxes
– The system cables are designed for standard cable glands.
– In order to apply other cable cross−sections, you must use extensions, reductions,
or other cable glands.
