Default Electrics, KVA, can someone explain this please?

Power requirement : The normal maximum capacity for individual
domestic properties is 15kVA.

At 230v for a domestic house, how many amps is 15kva? Trying to find out how many amps I can draw before melting the incoming power supply cable.
For now lets pretend there is nothing to protect the incoming supply.
The network operator wont tell me how much current I can draw because I may try to draw that amount of current. yea, so? If you tell me that is what I can draw, and that is what I draw, whats the problem?

Even working out what one may draw is not as easy as one may think.
fridge, freezer, cooker, washing machine, tumble dryer, toaster, kettle, electric heaters bla bla bla.
My compressor will momentarily at start up draw 30 amps but drop back to 20 when running. Ask a number of manufacturers the start up value of their products and you blow their minds.
