Re: How to Spec a Dedicated AC Line?

Hi
Don’t fool with power systems unless you know exactly what and why about what you’re attempting.
Here is a link to one article that goes into what is involved.

Essentially all of the problems associated with wall outlet power noise and unbalance, that sometimes are even real, can be squashed with an isolation transformer.
Many of these transformers have low pass filtering and spike suppression, some, the kind called resonant transformers (like Sola makes) regulate the voltage and put out a constant Voltage sine wave too even with a distorted input. These devices do tend to make airborne noise so they should be located in another room, not in the listening room..
Large computer systems used to be real sensitive to power supply variations, the best place to look would be for a power isolator that was removed from service.

For example, here is a 500 Watt unit that is on e-bay.

And a 2KW unit

Understand, these ARE NOT a UPS supply, they just regulate / isolate and clean up house AC for sensitive electronic equipment.
Skip the exotic wire unless you already have it, it makes no electrical difference at 60Hz. Use conduit or armoredflex cable (BX around here).
Best,

Tom
