New Electrial Wiring..

John,
There is a dealer here in Arizona that carries the New Cardas 10ga wire for the house.Can get pricy if you are doing long runs..but really good stuff.
Check it out at www.dedicatedaudio.com

I recently had an electrician run 3 dedicated, 10ga lines for my equipment. I used 20 amp breakers for all the lines and Teslaplex outlets also on all 3. (Read the reviews) Also you want to make sure that the breakers in your box are put in out of phase with the refrigerator or furnace/ AC breakers. One outlet is for Amp and preamp. One outlet is for digital and the third if for all other front end stuff, TT, etc. Sound of my Cary stuff after completion is really resolving. Surprised at the huge difference.

Consider at least one dedicated grounding rod for the stereo. Also, Walker Extreme SST on all contacts in the box and at the outlet.

No "dedicated" or separate grounding rod. A supplementary grounding rod must be bonded to the main grounding electrode. I won't repeat myself as to the whys here. See the following link to previous discussion in a recent thread.

All lessons the chance of ground loop hum problems.

Gbart,

NEC 2008 the word "supplementary" was dropped and replaced by the word "auxiliary". There was to much confusion being made between Supplemental Electrode and Supplementary Electrode.

250.54 Auxiliary Grounding Electrode. Page 70-106.

Section wording is the same as NEC 2005. The electrode need only be connected to the equipment grounding conductor of the branch circuit. The equipment grounding conductor still has to connect to the ground bar in the electrical panel the branch circuit is fed from.
