AC/Generac Transfer Switch

Hi, I'm building my retirement home and for the first time will have a true dedicated media room! 

The room will be wired with 2 - 10AWG 20A Circuits soloed for the equipment, lighting will be on a separate circuit to avoid line noise. My question is on the whole house transfer switch hook up. I've read in previous posts to not use circuits post transfer switch for audio power as it puts noise in the line. If that's the case do I put in a sub panel pre-transfer switch solely for the 2-20A audio circuits? I also had the electrician pull a separate earth ground specifically for the 2 circuits not tied to the main panel. Any wisdom would be greatly appreciated!

As things progress with the build I know I will have more questions for the wise ones on here to guide me!

Thanks, 

K

All switches put noise on the line when they break contact. The transfer switch won't be a problem when closed against utility power.

You cannot use a subpanel at the service anymore if your local building department uses the 2020 NEC. That panel will have to be a service entrance rated panel (load center) with a main breaker disconnect or a switch in a separate enclosure ahead of the panel if it's not a load center. 

I would say talk with your electrician, but if he installed more than one ground at your house I doubt he's got a license.
