Are electricians very cheap where you live? In the US Northeast, I was quoted several thousand for an EVSE install that was about 30' from the breaker and had room in the panel. The hardware is only a couple hundred.
There are plenty of people who are capable of grasping what the three wires (Or whatever the USA has) do and where and how to place and connect them, but there are also fuckwits.
My concern is that this change to the electrical code would impose needless expense on responsible people, while doing nothing to discourage the the irresponsible ones.
