Power distribution box calculation
Pe is the rated power
Kx is the need factor
cosO is the power factor
Pjs is computing power
Ijs is calculating current
Pjs=PeKx Ijs=Pjs1.52/cosO

Pe active power, Kx need coefficient, Pjs calculation power, Ijs calculation current. And CosΦ represents the power factor.
The relationship between them is as follows: Pj=KxPe. Ij=Pj/(1.732Ue*cosφ), ue=380V is the rated voltage.
Among them, 1.732 is the square root of 3; P=root 3×U×I×power factor;
