14.59 upgrading of standard domestic supplies to accommodate high amperage charging would be a collosal task. A standard dwelling is supplied by either 2 cores, or a concentric cable which consists of a core for the phase and the return or neutral conductor would be the sheath. Two phase supplies would be problematic unless studies carried out and designs in place to distribute the 100 dwellings evenly across three phases. Supplies need to be evenly distributed across all 3 phases to reduce imbalance, which causes problems further up the network with protective devices and cable characteristics. If you were to upgrade street of 100 houses, each and every house would need a new cable, new distribution board and re-configuration of existing circuitry to balance load and reduce risk of exposure to 400v. The network supply cable would need replacing back to its source, ie local sub-station with transformers and protective devices needing up-graded.
Maybe now is the time to invest in your regional DNO?
