Abstract: A miniature circuit interrupter for interruption of a primary circuit, the circuit interrupter formed or molded with a plug, connector or the like, the plug or connector being non-serviceable and the circuit interrupter therein being sealed and watertight.

Abstract: An under floorcovering heating systems for positioning below a floorcovering is provided. The systems include pads having a heat conducting substrate within which is positioned solid conductor resistance heating wires in a serpentine manner for heating the substrate. The wire is covered by at least one layer of material providing electrical insulation and strong mechanical strength, jacketed by an electrically conductive "self-healing" ("self-curing") strong layer of material for the purposes of grounding and protecting the system. Also provided are electrical connecting mechanisms for connecting the resistance wire to a source of electricity including mechanisms connected to the jacketed conductive material for grounding the system.
