We had a '7.2kW' installed into in-laws appt for our car. Thankfully a relatively easy install for location and used the same guy that had done another so he sort of knew the setup. Should point out at this point that the guy needed industrial installation qualifications, so not a regular spark.
A short while before install, by chance, the (residents) management committee put out a request to see if people wanted to install communal infrastructure for EV's. No takers except us, so when we sought permission, it was granted on basis that we paid the whole works (we expected that and no OLEV) but would have to follow the model, ie connected to flat meter (and installer) of the first (and up to that point, only) roadgoing EV install.
I had a long chat with the spark whilst having to act as go between him and some irate residents who has their power briefly disconnected and some wanting to barge into the plant room communal sockets to charge their golf buggy batteries whilst the front was off the fuse/distribution cabinet
(quite frankly I should have let them electrocute themselves with their attitude, but thats another story). It transpires that not going with the communal infrastructure is a big mistake. There are quite a few flats sharing the same phases of the 3 phase supply, via a huge fusebox and distribution cabinet - hence the need for industrial install. I believe that each phase is rated at around 140A, so equivalent of around 50A per flat without diversity.
The plan of the communal infrastructure was to balance the supply somehow for all flats to share, but without the communal effort, its a first come first serve on the capacity of each of the 3 phases. Thankfully the first EV and ours are on different phases, so the spark was happy to sign us off on a dedicated 32A charge point. There is one more phase without a charge point, after that people will not be so lucky and certainly no spare capacity on which to install further dedicated 32A devices.
