Notes: This calculator uses approximate copper conductor resistances and typical ampacity values. It computes per-appliance currents, voltage drops (round-trip), suggests wire sizes with auto-upsizing for voltage drop, MCB ratings, and estimates total cable costs based on individual runs. Always consult a qualified electrician and adhere to local regulations.
