how does the current divide in a three phase system?

Question

So let’s say that I have a three phase system has a current absorption on 30A. Are these 30A divided 10 per phase or are these 30A per phase, which brings the total to theoretically 90A?

Answer 1

There are different 3 phase systems possible, Star/Wye and Delta. Depending on which you use, the current is divided differently.

[https://en.wikipedia.org/wiki/Three-phase_electric_power](https://en.wikipedia.org/wiki/Three-phase_electric_power)

If the power draw is balanced between the phases, the current is the same in each phase.
However there are 3 phase loads that have widely different currents in each phase.
