Attached is a birds eye of my local sub station, that grey building between the two houses.
UK wiring is pretty conservative. Outlets arte wired in 2.5mm sq about 13 AWG but also as a 'ring'. At the fuse board (aka 'Consumer Unit) 2.5 mm goes out to a ring of sockets, typically ground floor say then returns to the same breaker point in the CU. Thus each outlet is 'served' twice. Each ring is rated at 32 A giving a nominal rating of around 7.5kW but then each appliance has it own fuse in the plug of 13 or 3 amp rating.
Heavy drain devices, cookers, showers are spurred back to the CU in heavier, 6 or 10mm cable.
