TL;DR — Quick rules you can apply today Calculate load current: Iload=PV×PFI_\text{load} = \dfrac{P}{V \times \text{PF}}Iload=V×PFP (single-phase). Continuous loads: choose a device ≥ 125% of design current (or per your local code). Motors/transformers/LED drivers: expect inrush; start with Curve C (or D for very high inrush). Choose leakage type: for smart RCBOs, default to...
