That's why, for one of the mountain-top comm sites that we designed for
a desert site out in the middle of nowhere, we specified - ready for
this - 900 Kcmil conductors (*) for a 120/208V 400A feeder because the
power company located the CSED (Customer Service Entrance Device) i.e.
meter and main breaker installation  - at a point down the hill that
they could reach in any weather.

(* Visualize copper-filled garden hose.  3 sizes over minimum code (4/0
AWG) to minimize voltage drop and conductor heating.)
