I took the picture during an Infrared inspection of the electrical distribution equipment for a small manufacturing facility. It is a 2500 amp 480/277 service. It was installed 25 years ago. The picture shows the point of entrance from the utility transformer to the CT cabinet. The service is hot sequence metering. The lugs shown are the line side of the CT's. The 1 1/4" PVC carries the wires between the CT's & the remote utility meter. The small conductor zip tied on the left was for the neutral connection for GFP of the main disconnect.
