Installing Charger Unit and Junction Box

What happens here

With the back plate securely mounted, the main IYILO EV charger unit is carefully placed onto it, sliding down to lock into position like a picture frame. Next, a 4-inch metal junction box is installed directly adjacent to the charger. The charger's flex whip is then connected into this junction box using a 1-inch liquid-tight connector, which is crucial for a secure and weather-resistant connection. Inside the junction box, the three conductors from the charger's whip (black hot, red hot, green ground) are connected to the corresponding 8/2 Romex wires using appropriately sized wire nuts, ensuring proper L1, L2, and ground connections.

Goal: Connect the charger to the power supply via a junction box
