Yes you are correct. They only have single phase and want to add a 3 phase panel. So I will need to use a current transformer? Should most electrical supply houses sell these. I asked the supply house I use if thats what I needed and if they sold CT's and they acted as if I was the only electrical contractor to ever ask for meter equipment for a 400 amp service. They said the highest meter they sell is a 320 amp, 3 phase.
