Page 2-22 - Page 43 shunts, current transformers, and voltage (potential) transformers, should be packed in separate boxes to avoid possible damage to the instruments. Heavy pieces should always be shipped in wooden boxes and held in place, if necessary, by checks or cleats. Large transformers, especially those having oilfilled iron cases, should be crated separately and arranged whenever possible so that the terminals can be made accessible for tests without removing the entire crate. (7) The tops of boxes...
