Wire size

Hi all

Is there a guide anywhere as to what wire diameters are suitable for
secondary windings at different power levels? I am thinking in the range
of 2 to 10 KVA. I have an idea what is suitable in the sub 1 KVA range
but I do not want to wind a secondary only to destroy it with too much

Any pointers appreciated.
