Install A Dedicated AC Line at home

Adding two dedicated lines using materials on hand and a very long history either full time or as a hobby, 60+ years including 20 as a tech on very high end military systems, to gain whatever is actually possible and not just a change in sound as seems to be what most high cost cables, AC, etc cost.

We have a bunch of wifi power meters close by so also shielding the walls as I remodel and metal grounded window screens.

Power Guard RV permanent mount surge suppressor with remote monitor, nice to see the loads on each 50 amp leg as I turn things on and off. Already had this from prior RV, waited to long to install it, just finished it today.

Separate noisy from quieter circuits per leg. All power cables, Ethernet, etc are located at a distance from each other, c

1) 10 gauge THHN 3 wire twisted at 2 inches per turn. 1/2" aluminum flex connected at the panel but not touching anything metal on the way to heavy gauge plastic boxes, any noise goes back to ground at the panel. Leviton Plus+ 20 amp receptacle, not grounded to box or conduit. 33ft run, likely only used to power sub amp.

2) 12 gauge THHN assembled as above except two outlets down low and one up near the ceiling for the TV and Martin Logan soundbar( used when not playing the regular system) Conduit will be connected box to box but not to the outlets.

Far more current capacity than I will ever need, by design.

Computer likely powered off other nearby circuit though I will test all possible combinations with amps, DAC, etc......too see what might sound better.

I have two good quality surge suppressors I can add to the wall outlets to test as well.

Investment, new money of a few items, under $100, total with RV surge suppressor, likely under $600.

After all is done and tested I will then consider some kind of very reasonable priced power conditioner, possibly DIY, rebuild a dead one, etc...but only if it seems it wold be needed.

Also planned, DIY power cables in the $50 range.

For those willing to spend tens of thousands on wiring, cables, conditioners, etc...cool, have fun in this great hobby, at the bare minimum at least it is good for the economy but if you are happy with it, by all means do it!!!

Also using Square D breakers, already on hand.

Will apply good paste to all connections except plugs into outlets, I will used a can of ProGold to spray those. I saved the military many millions using that stuff, brought in my one can to show them it worked then bought it by the case.

Thanks all, I really apricated. Sorry about delayed reply ( stuck into my busy working day yesterday) This is great leaning curve to me to get onto this really necessary Dedicated AC Line for my home audio system, please continue the thread. 

For those interested; more white pages on AC power for audio:

Power and Grounding for Audio and Audio/Video Systems

You want two, one for your main components and a separate for your amp.

Overkill if you understand electricity. Just be sure to wire the two circuits on the same AC buss. And choose the one without refrigeration, etc. 

2 grounds ,one common ground ,the other a insulated isolated ground on a separate Copper buzz Bar, amd a 2 inch  4 ft long ground

Bad choices. Adding additional ground rods can reduce the efficiency of the Earth which is there primarily for lightning strikes on the power lines. Unless it was engineered, you probably made things worse.
