    Check the rated primary current. Choose a CT with a rated primary current that is slightly larger than the maximum current that will be measured (ex.: 100 A, 200 A, 300 A, 500 A, 800 A). The rated secondary current is typically 5 A, but there are also 1-A transformers. Single ampere CTs are useful for long-distance wiring. Check the rated load.
