If your panel still has a couple of extra spaces, run 2 dedicated circuits from them with the appropriate breakers to your system. You don’t need a wire encased in metal. The ground at the panel end goes to the ground buss inside the panel. The other end goes to the ground on the receptacle in the audio room. Why make it harder than it needs to be? I have 2 circuits like this for 23 years with zero noise and zero problems. A licensed electrician did all the work.
Dedicated Circuits - Subpanel importance?
My system is no more. Sold everything. Starting from scratch. Thanks to you and seven months of experience I am doing the following, which is taking care of the number one component, the room:
- Treating. The full GIK order in October is starting to arrive.
- Running one or more dedicated circuits.
I am addressing #2 in this post. There are extensive discussions here and one can spend hours if not days trying to wring-out the critical details needed for a DIY solution. I have spent hours and there a few things I need to confirm before I proceed because I was unable to find definitive answers.
I am doing this myself. I do not want or need lectures on only having a licensed electrician do this work. I have been doing my own electrical work for many years and am very comfortable doing so.
- Does a subpanel help? Is it required? Subpanels are typically supplied from a breaker off of the main panel's bus, so I'm guessing there is no advantage in terms of SQ? Perhaps if I can independently ground the subpanel it might make a difference?
- Opening up my walls is not an option, so I need to use conduit. This may restrict the number of lines if the wire should not share the same conduit? If I am restricted to Romex 8 or 10,2 versus metal-clad, is it okay for two runs to occupy the same conduit?
- How much better is metal-clad? Is it required vs Romex? Will metal conduit accomplish the same result with Romex?
Answers to these questions will complete my plans and I will go forward at speed. Hopefully this discussion helps others as well even if it's to know what to have their electrician setup for them.
Thank you!
