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.

Don't we need metal boxes at each wall outlet and each metal box gets its own ground wire ran back to the panel? These grounds are separate from the romex. 

I don’t like MC cable or wire in a steel pipe.

I agree with your statement for use of steel armored MC cable or loosely pulled conductors in a steel conduit for the reasons you stated in your post dated 02-24-2023.

I do like and recommend 2 wire with ground solid core copper conductor aluminum armored MC cable though. ( MC, not, AC cable. ) The aluminum armor does reject some RF from entering the cable. What I like about aluminum armored MC cable is the Hot, Neutral, and insulated EGC, conductors are twisted in a spiral twist and held firmly, tightly, together by the aluminum armor.

Price for solid core copper 2 wire with ground aluminum armor MC cable is competitive with NM cable in my area. I agree twisting the hot and neutral current carrying conductors together and pulling the EGG along side the twisted pair pulled in conduit is better than AL armored MC but the difference, to me anyway, does not justify the additional cost, especially the labor cost... If cost is no object well then....

Note: MC cable should only be installed by a licensed electrician that has experience removing the armor from the wire for termination.

For anyone interested:

Power Distribution and Grounding of Audio, Video and ...

Read pages 4 and 8.

Closely read pages 11, 12, and 13.

For Isolation transformers read page 19.

.

I have dedicated circuits but still they don't address the noise issues which are a shared problem with everything else on the panel.

So I Think it should be recommended to additionally install a Power conditioner of quality that does not impede the flow of electricity.

This combo of Power conditioners and dedicated circuits seems optimal. I use a Transparent Power isolator which I use to plug in my amplifiers.

Additionally now that people have 10 gauge dedicated circuits they need to replace all the power cords what's 10 gauge Power cords. Doesn't this make sense?

MC cable is manufactured in both steel and aluminum with twisted conductors that help reduce AC magnetic fields. Also, steel MC will help reduce EF. I am sure you know that. 😎
