I've found very little good information out there..
Here's some:
From that page:
"Electronics grade power distribution panels have a number of primary differences from a standard electrical distribution panel. An electronics grade power distribution panel and wiring system will always have the below configuration.
* The primary neutral conductor and the neutral lug are oversized, (sized two times NEC requirements), to deal with harmonic currents generated by switch mode power supplies.
* The neutral conductors in branch circuits are home runs (never shared or used by more than one circuit).
* Panel grounding and conduit ground is case ground and a separate isolated ground buss bar will be installed. This isolated ground buss bar will be connected directly (and only) to the service entrance ground buss bar with a stranded and insulated copper conductor sized appropriately for the distance involved.
* Circuit breakers are electronics grade "bolt in" breakers.
* Only Isolated Ground outlets will be used (phase, neutral, ground & case ground)."
and some resources here:
From that site, this in particular:
My take-aways from that page include:
* Double-Size Neutrals, or Separate Neutrals per Phase
* Separation of Sensitive Electronic Loads From Other Equipment
---- "power sensitive equipment from separate branch circuits emanating from separate panel boards, fed from separate feeders back to the main service entrance. The neutrals and grounding conductors need to be kept separate also. A dedicated circuit means separate phase wires, a separate neutral, with a separate grounding conductor, run in its own separate metal conduit, back to the source."
* Metal Conduit
---- "Metal conduit, properly grounded, provides shielding of the conductors from RF energy."
* Upsize Conductor Gage
* Test Ground Resistance, Upgrade if Necessary
My new home was built in 1936. The home inspection revealed that over half of the power receptacles have reversed polarity and that the panel / fuse box is quite old. So, I'm expecting a major electrical system upgrade as I am a both a stereo and computer nut. Fortunately, my computer/stereo room will be located in the basement close to the service inlet, and the walls to my new HT room aren't framed in yet. These features can only make any tweaks to the room easier, so I'm starting my research now.
Comments, questions? Thanks!
