Dedicated power lines for audio?

Go to electrical supply store and get 12ga romex and as many hospital grade outlets as you need. 20amp breaker and your done. hospital grade outlets hae a green dot on them. Don't accept anthing but the green dot. Don't be fooled by these audiophile outlets. theres no substitute for the green dot. Expect to pay 20-25 for each.( 8ga wire is a ridiculus overkill)

Leemark; I used 6 ga. wire because I had it, and it was already wired into my main breaker box. It used to feed a 180 amp arc welder, and for that was certainly not "overkill". A mainline wire is only needed to go from the main breakerbox to a submain breaker box-- I preferred that because I wanted 4 duplex outlets, but did not have the room in my main breakerbox to wire them in individually. And of course, you're stuck with the "house" ground if you come directly off the main breaker box. There is disagreement about the value of grounding individual outlets and grounding just the submain (I grounded the submain). But a good ground is probably as important as the dedicated lines. High quality ICs, speaker cables, and power cords are almost all made of large gauge wire for a reason. Thicker is better, but of course dimishing returns are reached at some point. Hubbell outlets are well regarded for many uses as well as audiophile, and it appears that at 2 for $25. are less expensive than hospital grade. Regards. Craig.

remember too to observe phase when placing your new breakers in the panel. Always keep breakers on the same phase. For example mount all your dedicated lines on the same side of the box. Craig I feel sorry for the guy that had to work with your 6ga romex.

Hi Leemark; Good comment re: phase. The 6 ga. wire I used is stranded TPC (tough pitch copper) and all the electrician did was reroute it from my garage, through the attic, and out an attic vent screen (to the outside). So actually that part went pretty smooth and easy. My sub-main box is on the outside of the house, and once there it was pretty straight forward for them. The dedicated AC lines and ground really made a nice improvement in music. Cheers. Craig

I ran my own dedicated line: three strands - the usual black, white & green (with some advice from Mike VansEvers) using #10 solid THHN. Line them up straight, & tape the ends all together. Put that combo into your power drill chuck & fasten the other loose ends tight in a vice. Now spin the whole bundle slowly until tight like a spring. It will unwind a lot when you power off the drill. Exchange ends & finish the twist. Run this bundle from the fusebox to a dedicated outlet. BTW: a 20A ceramic fuse sounded much warmer & smother than the glass fuse.
