The present invention provides an expandable and flexible apparatus that can be installed on a device including but not limited to a bushing current transformer (BCT), a control power transformer or a toroidal power transformer. Such an apparatus provides at least one connection point on the device that it is installed on. The apparatus comprises a terminal, a terminal plate, a terminal plate expansion strip or a combination thereof. The apparatus is novel because it has an expandable connection that allows for many terminals to link and be positioned in desired configurations and distances, a linking system that makes the apparatus flexible and allows it to follow the contours of the device, and an anti-rotational provision that holds the terminal in position while the user is connecting wires to the apparatus.
