Hi William, On these types of"small space" installations of CT's I've used Rogowski coils, flexible CT's for all intensive purposes. I've bought them many times from Aim Dynamics and they are very reasonably priced and they're engineers are easy to work with. Tell them you want Rogowski could with those specs and they'll get them to you fast and affordable.
