dedicated curcuit question????


I am in the process of having an electrician friend run a dedicated curcuit to my HT-2 channel system.I currently have 2 seperate systems in the same rack.My 2 channel(power amp,cd player,preamp,DAC.My HT system consists of an AV reciever,DVD player,5 channel amp,vcr,cable box and a 36 inch TV.I have most of my gear plugged into a power conditioner,surge protector(Monster Cable HTS 5000) My question is: I can run whatever I want everything is very accesible(its in my basement) Should I run 2 seperate lines from 2 dedicated curcuits? Should I use a 20 amp breaker? What about an isolated ground? I was going to use the PS Audio power ports for outlets.Are these worth 50 bucks apiece or is it overkill? I would greatly appreciate any advice?

Krelldog,

This has turned out to be an interesting thread IMO. There is a lot of information already given. Some I agree with, some I don't. You should use the search feature to find many threads to do with this subject. KEY WORDS LIKE *Dedicated* *Dedicated circuits* and *Voltage drop* should bring up plenty.

It is never my intention to bash anyone’s comments as I can see their intent is genuine and sincere. Having said that I will say that I am an Electrician in a very High Tech area (Silicon Valley) And I have the mindset of an audiophile. Which is to say I believe in the best possible installation for the money invested.

I have installed six dedicated circuits in my own home and many in other peoples homes not to mention twenty-years in the commercial end of the industry (Impressed yet?)

My 2-cents on this topic would be run four or even five dedicated circuits (Mainly because you have a lot of gear) each with it's own dedicated neutral. Also add an isolated ground and a dirty ground to the receptacle location.

Use I.G. rated receptacles; you should probably run a 1" conduit between your panel and new location to cut down on labor and material. You will be required to pull #10 wire by code because of a de-rating issue when pulling more than five current carrying conductors in a raceway. THHN wire will work fine and personally I'd use stranded because it's easier to work with.

I recommend 5-hots 5-neutrals 1-isolated ground and 1-dirty ground.

Try to get a Commercial grade Electrician to do the work as opposed to a Residential Electrician. A Residental Electrician won't understand what you’re trying to accomplish, and may look at you funny.

Keep in mind the issue is not the current demand of your system but rather the isolating of different types of components from each other. This will lower the noise floor dramatically.

Don't forget to report back when it's all done.
Good luck!!! :^)
Krelldog, checkout the cryo/silver ACME plugs.
Spoken highly of at AA, I just picked up 4. Maybe today or next weekend I'll have them installed, into 4 20amp runs.

LAK,KILLERPIGLET,GLEN,andBILLM- Thank you all for great advice.I am going to have to live with 2 dedicated lines.Thats all the room I have left in my panel.I am going to use Hubbell 20 amp isolated ground outlets.My electrician can get them from a hospital he's doing work at.I will print out the reply's I got and show him .But for the record he thinks its a great idea,and its not like he's charging me much(a case of beer and a good bottle of whiskey)of course for after the job is done.LOL Thanks again.This website is awesome. Thanks John
Krelldog - don't skimp on the whisky...a good single malt can lower your noise floor up to 5 dB!
Krelldog,
He could easily run a sub box off your main panel so that you could run additional 20 amp dedicated circuits (or what ever where ever you want), if you desire. It's easier to do it all at one time than have to come back at a latter time and redo the job (but not the end of the world).
I also use the 20 amp Hubbell isolated ground outlets, they work well.
