Current Transformer
Current Transformer Panels are sometimes required in the switchboard when additional CTs are required in the main busbar either for Metering or Protection.
In cases where the weight and size of the CTs are small, they can be fitted in a TRUNK between two panels. When the total weight and size is large a panel is used to house the CTs.
