Step-by-Step Guide: How to Install a Home EV Charger in Nepal

Wake Up Every Morning to a "Full Tank"

One of the greatest luxuries of EV ownership is never having to queue at a petrol station again. Over 85% of EV charging occurs quietly at home while you sleep. But setting up an AC home charger in Nepal requires a few crucial electrical considerations.

Step 1: Check Your Electricity Meter Capacity

Most standard households in Kathmandu are equipped with a 15 Ampere or 30 Ampere single-phase meter. A dedicated 7.4 kW home wallbox draws roughly 32 Amps at 230V. Therefore, you should apply to your local NEA branch for a 30A or 3-phase meter upgrade to prevent main breaker trips.

Step 2: Choose 3.3 kW vs 7.4 kW vs 11 kW

• 3.3 kW Portable 16A Charger: Plugs into a standard 16A industrial socket. Adds roughly 20–25 km range per hour. Ideal for overnight topping-up on smaller 30kWh battery packs.
• 7.4 kW Dedicated Wallbox: Hardwired with dedicated 6 sq. mm or 10 sq. mm wiring. Adds 45–55 km per hour. Fully charges most 50kWh–60kWh batteries in 7 to 8 hours.
• 11 kW / 22 kW Three-Phase: Requires a three-phase connection and an onboard charger that supports 3-phase AC input (such as Hyundai Ioniq 5 or Avatr 11).

Step 3: Crucial Safety Measures

Always ensure a dedicated Earth pit with earthing resistance below 5 Ohms, an independent Residual Current Device (RCBO/ELCB Type B or Type A+6mA DC), and proper lightning arrestors. Never use standard extension cords or domestic 5A sockets!
