A dual element comprises two electrical heating elements of different ratings. Each heating element has first and second terminals. The second terminals of the two heating elements are secured to a common clip, which is wired into an appropriate electrical circuit. The heating element first terminals are secured to respective clips. A second wire of the circuit is connected to a selected one of the first terminal clips, thereby determining the power rating of the dual element. A jumper is provided that is selectively installable between the two first terminal clips. With the jumper installed, the second wire may be connected to either of the first terminal clips to thereby place the two heating elements in parallel. The rating of the dual element is then the sum of the ratings of the two individual heating elements. In that manner, the dual element is operable at three different ratings.
