Two physical grounds??


Due to construction issues the only way to ground my line conditioner is by instaling a dedicated ground rod for it (i.e. the house outlets are of type that accept a 2 prong plug). This dedicated ground rod for the line conditioner will be about 16 feet away from the ground rod for the electrical wiring for my house. By doing this would I get into trouble regarding a "ground loop".

Jim,
I just checked the 2008 hand book:
This 5-ft limit also applies to the replacement of nongrounding receptacles with grounding-type or branch-circuit extensions in accordance with 250.130(C). See the commentary following 250.130(C) and the illustration that accompanies that commentary, Exhibit 250.51.
I stand corrected. Not the first time! Peace T. J.
Sorry, my mistake and no offense taken. I assumed you had grounded outlet boxes. Most 2-prong receptacle wiring in older houses that I have seen built since 1960 is armored steel BX (with ground) and the outlet ears against plaster so installing a grounded outlet was... easy. I had gone with I was familiar with; I should have clarified with a question first.
