We failed an inspection today on grounding and the inspector seemed unsure and I believe he made a bogus call. Here is the setup. We replaced panels on a trough fed service. Old panels were FPE and one was a 200 amp and one was a 100 amp that fed an old electric furnace. We installed 2 new 200 amp panels in place of the old equipment. We had a 320amp/ 400amp meter with one set of conductors( not parallel or double lugs ) from load side of the meter to the trough fed with 250 mcm I believe. For a full picture I tapped in the trough (clear taps) and fed both panels with 4/0 seu. From my electrodes I went to the ground plate/bar in the trough and then to panel #1 and then to panel #2. the GEC IS #6 copper and wire is uncut/continuous. We also ran #4 copper from each panel to the main water shut off valve. The inspector was probably confused and was thinking of the trough like a disconnect but he said a couple of different things and finally settled on checking with his chief inspector. He got back to me at the end of the day and he said the chief wanted the GEC to terminate in the trough and the supplemental GEC to the water pipe to also go to the trough. Bond screws in ( which they already were ) and that's it. What do you guys think of this as this does not seem correct to me. We have done trough fed services before and have never relied on only a bond screw and a seu cable to bond a panel.
