EV Charger Load Calculator
A home EV charger is one of the biggest single loads you can add. See the current it draws, an indicative breaker size, whether it fits your sanctioned load, and how long a charge takes.
Indicative dedicated breaker: about a 40 A MCB (confirm with your electrician).
Charging while the home runs (10.2 kW) exceeds your 5 kW sanctioned load — you may need a load enhancement or to charge off-peak.
Indicative only. Breaker and cable sizing depend on the run length, derating and the charger maker's spec, and a dedicated RCBO-protected circuit is essential. A sanctioned-load enhancement is applied for with the DISCOM. All EV-charger wiring must be designed and installed by a licensed electrician to the relevant standards — this tool is for planning, not for sizing your actual circuit.
