Single Point Ground


I'm going to have a new room wired with two dedicated power circuits. I've read a single point ground is recommended. Can someone tell me if this is worth the effort and how it is done. I assume it is only important for the dedicated audio circuits.

thanks for any comments,

First, you need explain what your understanding of a single point ground is?

If you are going to have two dedicated branch circuits installed, and they will be installed per NEC and AHJ (authority having jurisdiction) in your area, you will end up with a single point ground.
A single point ground in a audio system could mean only 1 component is grounded. Typically the device that draws the max current. I have heard some 'tube' guys do that to eliminate ground loops/humming.

Well I posted because I wanted an explanation of exactly what it was, I've read it is desirable. But if it comes with Code wiring then that is all I need to know. Just puzzled then why it would ever be recommended if it's mandatory. thks for the reply.

Xti16 I have in mind the wiring my electrician will be doing.

Definetly do the dedicated circuits keeping your digital components on seperate circuits from your analog components .
Also put these on an isolated ground . Are you energy contious ? How many incandesent light bulbs have you switched to flourescent ? It is getting more difficult to isolate the noise makers now a days !
Make sure that your electrician is well versed in isolated grounds . This type of circuit is generally used in the commercial end of the buisness , hospitals and computer centers . I found that residential electricians were aware of isolated grounds but did not know the proper procedure for installing them !
see I have mixed up single point with isolated grounds, sorry. So can I start over are these recommended and how are they implemented.',

But I see I confused single point with isolated grounds,
sorry. So can i start over, is this desirable and how is it done?
