Power questions

Hello all.

New enthusiast here.  My question is about source power for my equipment. Im redoing the wall that my equipment is on. I use it for 2 channel and movies. Purpose is to increase distance between my left and right speakers and to get a larger tv. As an electrician, when i origionally roughed the wall I knew enough to pull a dedicated cct for the "entertainment system".  I never envisioned getting sucked down this worm hole. So...being that the wall is open i can easily pull another dedicated circuit. Perhaps #10 awg. So i would have 2 dedicated 20 amp ccts on the wall and a 15amp general purpose cct.  My equipment is as follows: Anthem mrx740 avr, Anthem 325mkII amp, Paradigm Founders 120H left and rights which have active woofers , a node streamer, and a Rell wireless module.  Behind the wall is the router for the house(stair case wall).  The amp powers my lcr speakers. The avr powers my surrounds. Questions are:

1. Would another cct make sense?

2.  How would equipment be best devided between the ccts? (I know this should probably be obvious but amuse me please)

3. Would pulling a dedicated neutral be better than sharing  a neutral as far as noise reduction?

4. Isolated Ground outlets?

Thanks for any input 





Yes, im in the chicago area. I wouldnt have. Problem running mc cable or romex just cannt get it to where it needs to go without major ordea.  I can however make the conduit run dedicated.  Thanks for everyones input. Great advice!!

Don’t confuse neutral sizing for commercial and industrial with neutral sizing for residential. (Commercial/industrial is 3 phase with neutrals that are almost always shared, and powering single phase loads can easily result in overloading of the common neutral. Also in residential (single phase) shared neutrals are dangerous, illegal in many markets and often cause problems when load imbalances occur)

As stated earlier, if you want more than a couple circuits in your media room, pull 8/3 or 6/3 and install a small subpanel.

Consider an isolation transformer beside your main panel. It made as much difference in my system as an upgrade of a major component.

But they can be noisy, so best sited away from your living spaces. Also eliminates need for special power cables - I experimented.
