An engineer friend recently recieved a request to look into the possibility of designing the installation for EV Charging points located on the top floor of a multi storey car park. The building is PME but begs the question of how can the EV Chargers be TT'd correctly ? IMO I would recommended chargers be installed on the ground floor if not only for ease of access (with the possibility of a disabled EV driver indiscrimanately having to park on the top floor) but also the TT spike installation would prove very difficult to install. My advice to him was to rethink the location but again wondered if anyone else had encountered this and how they approached the problem ?
