I do not have much knowledge with electricity.
But I would use a power cord that gives a lot of rooms , for high power peak demand.
Such as for subwoofer , powerfull amplifiers , etc.
I use PS Audio Perfectwave AC 12 power cord. 8 gauge.
You may find more refined power cord , but I am sure that with a 8 gauge,
it will be enough.
My power conditionner has 8 outlets , fully used with power amps ,subwoofers , for my Home Theater system.
