Abstract: An electrical terminal includes a barrel terminal having an L-shaped slot which includes a vertical portion which extends to the upper edge of the terminal, the vertical portion being in transition with a horizontal portion extending partially around the terminal. A cap which is profiled for receipt over the terminal includes an opening which is disposed diagonally through the cap relative the length of the cap. The cap also includes a window which exposes the opening from the end face of the cap for viewing the location of the opening and for viewing the insertion of the wire into the opening. Upon insertion of the wire into the cap, placing the wire in the opening and placing a tool over the cap which pushes the wire into the vertical slot, rotation of the cap and tool moves the wire into the horizontal portion of the L-shaped slot and terminates the end of the wire in a wire receiving slot.
