How to wire the building electric vehicle when charging?

The electric car is charged outside for a long time. In order to ensure safety, copper wire with white plastic double core can be used (the diameter of copper core wire is enough); It is recommended to use the "Bull" brand for the terminal board (this brand is recognized as good in quality, and other products with good quality can also be used). If it is only used for charging, there should not be too many jacks. It is best to connect it with a plug from a socket or wiring board near the window to the wiring board downstairs, and then pull it out of the room after charging.
