Dedicated circuit

We moved into an early seventies suburban above ground ranch style home. The town is mostly underground wiring. Before I had done anything I was auditioning the PS Audio HCA-2 class D switching amplifier. The clock radio in the bedroom was picking up interference from the audio system.

Having the mains service increased came with all new cable from the utility source. Code required losing the aluminum wire between the utility breaker and the homes panel.

From there I had a dedicated sub panel that fed both the two channel and HT systems. The runs were 10 gauge metal clad BX terminated with isolated ground (orange) receptacles.

For less than $800 the results were stunning.

What's your checklist of instructions for the electrician when doing the install? I've seen other threads on this.

I have two 20 amp dedicated lines for my audio equipment . One for the analog stuff and the other for digital stuff .
I then used hospital grade duplex receptacles , two for each line . I am now ready to do another dedicated line for the new tv going in for HT .
When you do the dedicated lines , have them done with an isolated ground system . This way you won't suffer from household interference . Things like florescent lights , refrigerators , hairdryers , microwaves etc. can cause noise in the system . This noise is particularly offensive if you have tubed equipment and/or high efficiency speakers .
I Googled 'isolated ground' electrical systems to familiarize myself with it . Then I called an electrician and used my google knowledge to make sure that he did know what to do . I had to let one electrician go because he did not know how to do it . I then wound up having to hire a commercial electrician . Make sure that the isolated ground system grounding rod is at least 6 feet away from the original household one . A few electricians get kind of funny when it comes to installing ground rods . I have seen a few cut the rod in half so that they didn't have to spend a lot of time and effort trying to pound in an 8 ft. rod ,
especially into rocky soil !
And I have tried an aftermarket power chord on my CDP . It made a noticeable improvement .

Good Luck

I meant 6 foot rod .
