5 Things You Must Know Before Installing an EV Charger at Home
Electric vehicles (EVs) are becoming more popular in Kathmandu and across Nepal. If you are planning to install an EV charger at home, it’s important to know a few technical and safety points before starting the installation. Proper installation ensures safety, efficiency, and long life for your EV charger and vehicle.
Here are 5 essential things to know before EV charger installation in Kathmandu:
1. Dedicated Wiring & Ampere Requirement
EV chargers cannot run on normal household wiring. You need a separate wiring line from your main meter.
For a 3.3 kW charger, you need at least 16 Amps
For a 7 kW charger, you need at least 32 Amps
Not following this can cause overheating, wire damage, or even fire hazards.
2. Proper Earthing
Earthing is one of the most important safety measures for EV chargers. Without proper earthing:
Electric shocks may occur
The charger may get damaged
Battery of your EV can be harmed
Make sure the installation is done with proper earthing to avoid any accidents.
3. Safety Devices (MCB, RCCB)
Always use safety devices like:
These devices protect your home and EV charger from:
Short circuits
Leakage currents
Overloads
Without these, installation becomes risky and unsafe.
4. Cable Locks
Using cable locks during installation is a small but very important step:
Prevents loose connections
Reduces the risk of short circuits
Ensures a safer and long lasting charger setup
Loose wiring is one of the main reasons EV chargers stop working.
5. Charger Location
Choosing the right location is crucial:
Install the charger in a dry and safe place
If installing outdoors, ensure it is properly covered and protected from rain
Water contact increases the risk of short circuits and accidents.
