    CT & PT Connection

    Bus bar passing through the CT touches the rubber housing of the CT. Is is ok or should there be a min distance between the bus bar and the CT housing ? Also is there a diagram out there showing a CT and PT connection?

    Typically, bus bar touching the CT will not have harmful effects. However, the CT accuracy may not be what the manufacturer states. The manufacturer should have a diagram illustrating proper clearances. Who is the manufacturer of the CT?
    Ever stop to think, and forget to start again?

    The CT should be insulated for the application. If so if it touches the bus bar or not is not an issue. If it is not rated for the application it is being misapplied.
