We had a metal prefab building built (4000 sq ft) that is powered from a pole mounted service that already feeds a trailer pedistal and site lighting. The service has 2 driven rods and so does the pedistal.
The new building feeders (208v 3 phase Y 3 hots 1 neutral 1 ground) where run to the service pole and are protected by a 200A breaker. The entire job was just inspected and passed, the inspector was on site less than 5 minutes.
I feel that the building should have 2 ground rods (should have had a UFER but it's to late now), a bond to building steel and the water service bonded. Before I go to the engineer and look like a fool am I correct? The project documents just say "Grounding as per NEC".
The job looks perfect, all conduit run in a very workman like install with ECG for all circuits.
If I am correct can someone give me code sections to have the engineer review.
Please note this is not DIY, I am the maintenance supervisor. We do not do installs only service what is already installed. I just want to make sure my employer gets what is required
I do not know if anyone remembers my post a few years back about stray voltage on this site but we finaly got LIPA to repair their problems, some as far as 1/4 miles away and got the voltages under control. Used to be able to light a 12v lamp between the ECG on a site lighting pole and the chain link fence on the Rail Road property. Just do not want a repeat of the problem in this new building due to bad grounding.
