In Reply to: What voltage are you guys doing your dedicated circuits at? 115 or 230? posted by Christopher Witmer on June 11, 2007 at 13:51:21:
Hi.
I've DIY installed dedicated powerlines for both my 120V & 240V gears, with inline powerline RF noise filters, discretely for analogue & digital gears, never mixed.
I simply tapped them from my house fuse panel which got both 120V & 240V terminals (typical for Northern American homes). The powerline coming in my house from the distribution transformer outside is already 120V-0-120V balanced (hopefully 100% fully balanced).
So you are correct for 220-240V audio equipment, using the 120V+120V terminals, there will a floating AC powerline situation where a forced
balanced can be achieved. This will help cancel out tons of outside RFI/EMI noise riding on the powerline into your equipment.
That's why I prefer 240V AC mains for my gears which are switchable 120V/240V.
But in this 120V+120V situation, bear in mind this is live wire for both arm of the powerline. Do not assume one arm is live, so the other arm must be neutral similar to standard 120V outlets.

PS: if you are not dead sure, do NOT, repeat, NOT play the fuse/breaker panel.
