I know the code says Neutral to Earth connection shall be made at every main service disconnection point and then be isolated on every panel afterward. In my case I have an overhead pole mounted meter disconnect with neutral to earth connection, then UG quad threephase wire to a UG vault with the neutral connected to the earth ground rod, then about 10 feet of secondary to the main disconnect panel in the building. I said the customer should also connect neutral to earth bond in the main disconnect panel and then no where else. Isn't this setup correct? The electrician suggested that this would set up a parallel ground path and questioned the logic. I suggested it was code. Any thoughts?
