Running supply voltage of 60/60 - Vs - 120/Neutral

Some gear has polarity sensitive filtering in it and going to a balanced AC system may negate many of the specific design attributes of such a design. Contact the manufacturers of the gear that you are running and discuss it with them before going any further. Anything less could be experimenting at your cost. Sean

Hi Sean it appears that Luke already has his balanced power setup in place; BTW isn't your own AC supplied via a balancing transformer? I recall your traveling to (Ohio was it?) a couple of years ago due to a bargain find on 2kva transformers. Wish that I had been working at the time but I was off for a year updating my data networking education; otherwise I would have liked to try one! So Luke if your reserach dictates that you'd be better off without then please do let me know...

"it's definatly a safer system as you would not get shocked unless you touched both legs at the same time."

Not if you wired the secondary of the xfmr correctly. The center point of the xfmr should be bonded to the main service grounding electrode system. Thus this is a grounded conductor. This is also the point in which the equipment grounds of this new AC derived system will tie to. You will have 60V to ground from either one of the two hot conductors of the 120V system.

What type of receptacles did you use? Isolated grounding type?

The grounding system i am using is a common all across system, so the primary and the secondary ground is the same, with normal outlet ground, i am having trouble with ac noise, on my sub (sunfire) it has a humm without any inputs attached, the grounding system may be the reason for it.

heres a pick for one of the transformers i am using, wich is dedicated to my sunfire sub, as it draws up to 2700 watts of ac power:

The input has been config for 240v in as thats what my apc runs on, and output taps 5 and 8, this system was made to be tough,mainly becaus of the sunfire high current draw.

Thank you for your help, i will keep posting on this thread as we discuss this matter,

Could you please explain in more detail.....

This being the unbalanced.
A single phase isolation transformer with one of the two secondary output leads bonded to ground. Thus one grounded conductor and one ungrounded conductor, 120V.

This being the balanced.
A single phase isolation transformer with a center tap secondary winding 60/120V,
60V-0-60V. The center tap being bonded to ground. Two 120V ungrounded conductors with a reference voltage potential to ground of 60V each.
