Re: grounding

OK.Do we have to consider a seperate earth conection for the 3rd pin in the computer sockets.What is the neutral to earth voltage to be restricted as per NEC.I believe SRG(signal reference grid )grounding is used only in data center/server rooms only.Is there any other place where to use SGR grounding.I want to know more about SRG grounding....
 
Re: grounding

There are no NEC requirements for this issue. This is a design consideration and not necessary for life or property safety.
