Here's a bit of an update.
I have now placed the Furutech at the end of an ordinary line,not a dedicated one, and the wiring is 14 guage romex standard house wire,into a standard wall fixture.
What I can now add is that even if you can't run a dedicated line from a 20 amp breaker and use 10 guage wire,you can still improve your sound if you use the Furutech GTX receptacle.
