In a triphasic system (any), is there a way to tell if the current is entering or leaving a phase/line/load just by the angle of the phasor of the source ?

In the following picture we can see the labels IA, IB and IC. They all point towards the load.

But we know that it's not the actual current direction

What is their actual direction when VAB=380<0, VBC=380<-120 and VCA=380<120 ?

Can I tell this by the angle ?

Star Load

As can be seen by this graph, in any given instantwhen two curves cross, two currents are leaving the load, while another one is entering. In another instant60 degrees later, in any direction, the reverse occurs.
