Dedicated power circuits

I’m having some electrical work done including a whole house

generator, surge suppressor, and a new panel box. I am also going to have two dedicated power lines run for my stereo. I’ve read a lot on here about how this is a really nice upgrade and would greatly appreciate any advice to help me along on my project. Right now the plan is two 20 amp circuits with 10 gauge wire. One for my amp and one for my preamp and sources. My equipment is a McIntosh MC 452, a C47 right now but a C22 in the future, Rega P8, Rose hifi 150b,  McIntosh MR 74 tuner and Aerial 7t speakers. I’m also replacing my panel box with a new one. It’s a brand from a company that’s out of business and the quality and safety is suspect plus there are no new breakers available.


So starting with the breakers, then the wire and finally the receptacles what should I be looking for? The electrician that just left here is planning on the new panel being a Cutler Hammer brand. Any help would be greatly appreciated.



So where do I find this twisted mc cable? All i see is untwisted or straight.

It's not straight, trust me.

Example of what to buy:

I highly recommend you hire an electrician to install MC cable.








I really appreciate all the helpful suggestions. What I’ve decided to do is 3 dedicated 20 amp circuits using the 10 gauge aluminum mc cable and eventually some nice Hubbell outlets although for inspection purposes the outlets will have to be cheap tamper resistant ones. Thanks again for all the help.

Make sure you tell the electrician you want 10/2 with ground SOLID copper conductor aluminum armored MC cable.

"MC", NOT "AC" armored cabled. Make sure he repeats to you it will be MC cable.


Be careful what you are buying now days when it comes to Hubbell outlets. Hubbell today it not the company it was years ago. Different owner.

What are looking at buying? How many outlets are you looking at buying?

Southwire Armorlite 125-ft 10/2 Solid Aluminum MC Cable

You sure you want to recommend this cable. Think of all the issue you are creating. I would never use it. Its what I removed from Fremers that was causing lots of issues.

And I'm pretty sure its not twisted anymore.  Most all that stuff is strait transmission line.  Its held together so the impedance/capacitance is stable.

If your really concerned about rejecting noise, put an isolation transformer in for amps.  Size it to feed the whole system.  Or use an Audio Quest type filter on the front end and amps to the wall.  Either of those solutions will get rid of a lot of noise.  MC does not get rid of any noise.  The aluminum may block a small amount of RF on the branch only.  Aluminum does not do much for EMF when cables are places side by side.

I personally say stick with Southwire NM cable or spend more and get grain oriented twisted.
