The puzzle plates are part of the standard supply of every WBT pole terminal. WBT pole terminals are protected against twisting thanks to the ‘nose’ present on the double step washer. This protection can (and should!) be optimised through use of the puzzle plate. In this case the distance between terminals has to be selected at 30 mm or 19 mm so that two terminals can be clipped together with the puzzle plate.
