I changed a 100a meter panel from fuses to main breaker.I drove a 5/8'' grnd rod at the service location,there was an existing main water ground in #6 bare copper,all copper water service from the street. The inspector required a second ground rod be installed"min. 6' from the first rod". I politely quetioned why we needed a second rod if we had an all copper water service.His reply was "if you have it tested by a third party testing service he would accept that it." I felt this was weak, but a second ground rod is cheap and the inspector needs to come back afew more times for other reasons.The job is 40 miles from my house and my van gets bad gas milage.
My question is does this make any sense to you guys. By the way the ground rod is about 5' above sea leval and very close to the ocean. You chould get 25 ohms with a piece of string the ground is so conductive here.
