I run the K3 and my radio equipment on the 120 VAC 20 amp circuit and the

I run my computer and other stuff on the household 120 VAC 15 amp circuit.

ALL equipment connected to the station should be powered from the same circuit. That includes a computer and accessories.

Study this pdf of the slide deck for talks I've done at Visalia, Pacificon, and to several ham clubs.
