Jim, Yes, Yes, Yes!, I think you read it wrong.
While multiple ground rods and multiple ground path are ok, National Electric Code requires them to be connected to the Utility Entry-point Ground. I have posted on this subject many, many times - any additional ground rods must connect to the entry ground rod (or point) for safety under fault conditions. I have 20 or 30 ground rods spread about for lightning protection - all connected together by #4 or #6 wire and also connected to the utility entry ground rod. Yes, the neutral wire is only to be connected to the safety ground inside the entry panel (sub-panels and wired electrical devices must isolate the two) - but we were talking about grounds, not the neutral. One additional note about ground rods at the service entry - I was surprised to learn (while building a rental house this year) that now 2 ground rods are required at the entry, separated by at least 6 feet, and connected together with a #6 or larger wire. 73, Don W3FPR Jim Brown wrote: > NO, NO, NO! > > Joe, who rarely ever gets it wrong, has led us down a VERY wrong path, > and you, who also rarely get it wrong, have followed him. :) > > It is the NEUTRAL that must be bonded to EARTH and SYSTEM GROUND at the > main panel/service entrance, and ONLY at that panel.
