I had previously inspected this subpanel and reported it needed a grounding conductor. Only 3 wires had been ran from main disconnect. The electrician called today and said he was complete. It had only been about hour from his call about starting the work to his call asking for inspection. It is about 100' to disconnect from panel. Upon inspection the grounding conductor looked loose in conduit. A little tug and like magic I had the newly installed grounding conductor. All 4' feet of it. See photo.
