[BC] Now, THIS is a job!

Actually, it applies to all electrical wiring. You can obviously have higher
temp rise in outside conductors. The type of conductor is specified for the
maximum rating and allowable sag of the conductor. Bad things happen when
115 KV sags in 14 KV for example.

Don't forget, conductors are much larger than they appear from the ground
and currents in the several hundred amp range are not uncommon.
