how to choose cable cross section?
because we need to take new cable and we did not decided to buy which cable we must take?
thanks.
alma i added picture your topic and
and answer of you question is in this link :
Determining conductor cross sectional areas source from schneider
In compliance with the recommendations of IEC 364-4-43, the cross-sectional area of wiring
systems and the protective device must be chosen to meet several conditions necessary for
the security of the installation.
The wiring system must:
- carry the maximum design current and its normal transient peaks
- not generate voltage drops above the allowed values.
The protective device must:
- protect the wiring system against any overcurrents up to the short-circuit current
- ensure the protection of persons against indirect contact.
The logigram in figure 6-1 sums up the principle of the method which may be described by the
following stages:
