ABB OmniCore C30 User Manual

Note
Any local standards and regulations concerning insulation and area must always
be complied with.
AC current in CP/CS
For specific applications where the correct cable dimensioning can depend on the
relationship between the period of the duty cycle and the thermal time constant of
the cable (for example, starting against high-inertia load, intermittent duty), the
cable manufacturer can provide information.
Country specific norms have to be included.
The wire is not dimensioned to take care of starting motors or transformers.
The following table shows how much AC current can be suppled with a specific
temperature, and the wire size.
