Installing an EV charger at home in Kathmandu? Complete cost breakdown for BYD, Nammi EV chargers including earthing, wiring and 24/7 installation.
How much does EV charger installation cost in Nepal?
In Kathmandu Valley, SDR installs BYD and Nammi EV chargers from Rs 1,650 without earthing to Rs 5,000 with proper earthing. Battery EV wallbox needs dedicated 6mm copper line, 32A MCB and earth pit tested below 5 ohms. Most homes need 10–15m cable run from DB to parking.
- Without earthing labour: Rs 1,650–3,000
- With earthing + earth pit: Rs 4,500–8,000
- Extra 6mm XLPE per metre: Rs 350–500
- 32A MCB + enclosure: Rs 1,200
Why earthing matters for EV
EV chargers push 7kW continuous for hours. Without low-resistance earthing, body leakage can be fatal. SDR tests earth with clamp meter and gives report before handover. For apartments, we run earthing to building main or drive new rod.
