ABSTRACT:
A solid plate plug-in top surface heating element which is interchangeable with a shielded spiral wire surface heating element. Rigid conductors connect to the ends of the resistive wire heating element on the underside of the solid plate top disk. The rigid conductors are secured in horizontal alignment by a bracket to which both are connected, and they extend outwardly in the horizontal plane. A pan covers the underside of the solid plate top disk and insulated portions of the rigid conductors pass through two respective holes in the side of the pan. The conductor connecting bracket is affixed to the pan and the insulated portions of the conductors. The distal ends of the conductors have terminals adapted for mating with a plug-in receptacle. The grounding bolt of the solid plate top disk is connected to the pan and a grounding bracket runs from the pan and surrounds the distal portions of the conductors to provide a terminal for mating with the clip ground of the receptacle.
