Yes, but why stop at 115V?

Think of the mathematics.

Double the voltage at a given power. You can halve your current.

Double the voltage and half the current means that for given acceptable...

Not sure how theoretical. A problem with 400 Hz is that it easily induces currents elsewhere. Which means you have leak currents, you have proximity losses and skin effects... Those things get worse...

But why 115 Volts?

400 Hz up in air BUT not on ground makes sense because of the inductivity losses. High frequency alternating current tends to have skin effects, proximity effects et cetera....
