   I was doing to an RCD test today and wasn't sure why I kept having to same problem. My megger kept giving me a CON message though all terminations were sound. Any suggestions? Thanks.

   con usually means a wrong connection to the megger. Did you check your connections?

   Most likely you have used the neutral lead
