Sub panel gets its own ground rod?

Hi all:Six years ago, I built my workshop about 150ft from the house with a100A service. I ran a four-conductor cable to the subpanel in theshop, and kept the ground and neutral conductors isolated from eachother. I did not bond the sub-panel ground to its own ground rod,thinking it might cause a ground loop and/or noise in the intercomcircuit bewteen the buildings. More recently, when I put in a spa withit's own GFCI breaker, I had several people advise me to drive aseparate ground rod for it, and that I should have done the same for myworkshop. So far, I have had no issues, but I want to make sure I didthe right thing.My searches here have yielded many debates on the need to keep theground and neutral bonded only in the main panel and not the subs(which is how I did it), but nothing about the ground rod question.Does a remote subpanel need its own ground rod or not?Thanks in advance,John.

Tom, I think that we have confused everyone who is following this thread enough so I will end it here. I will be attending a grounding and bonding class in a few weeks as part of my continuing education requirements. I will certainly be bringing this issue up in that class.

Out of curiosity a question for everyone: Is the original poster required by 2002 NEC standards to install a ground rod at his subpanel location? YES or NO, no more discussion PLEASE! :-)
