What it calculates
The “Electricity Meter Selection” calculator computes Meter max current in A from 3 parameters: maximum load power (kW), phases (1 or 3), power factor cos φ.
A standard physics formula used in educational and engineering tasks.
Example calculation
With parameters Maximum load power = 10 kW, Phases (1 or 3) = 1, Power factor cos φ = 0.95 the result is 60 A (Accuracy class for homes: 1.0 or 2.0).
