I assume this is possible but wanted to know whether anyone had done it so as not to reinvent the wheel. I’m getting the Wall connector but will probably be moving house in 12-18 months so I want to get it installed with a “tail” that can be plugged into a big power point, like a spa bath sort of bigger amp one. That way I can take it with me and get sparky to install a 30 amp point in the next house and then just plug it in. Saves me having to buy a new wall box or pay more to get the old one uninstalled and then reinstalled.
