Give me the form number from the meter face and maybe I can help. No such thing as 4 element by the way.

8 jaw, I must have a sheltered life. 5 or 7 jaw no problem. Neither of which need ct's or pt's.

Were the ct's moved? If not has anyone checked the polarity of the ct's. I like to run both wires from the ct to an accessible shorting block. I do not like it when some one decides to save $0.13 and use one common for all of the ct's and one positive wire from each one. A shorting block saves the coordination time for the shut down that is usually needed to work safely. ( in my experience)

My WAG is that the "third party reversed the polarity of the ct's when the meter was moved. Common mistake where I live and work.
