An electrical device comprising in combination:
- a main electrical power-source means for receiving main and full power from a main electrical power source;
- an electricity-carrying means for conducting electrical power to a main electrical utensil circuitry and having a composition, shape and structure characterized by and upper limit of a first predetermined maximum amperage-capacity at and above which potential fire hazard exists from overheating of circuitry and combustible matter associated therewith thereby heated to combustion temperature, and for safely operatively functioning and connected in series with said main electrical power-source means, for conducting main electric current in series to a main electrical utensil circuitry, with the electricity-carrying means positioned and located before any utensil main-power electrical circuit of a utensil in electrical series therewith, at electrical amperages at and below a second predetermined amperage at and below which said electrical utensil circuitry and associated combustible matter safely function devoid of fire hazard, said second predetermined amperage being below said first predetermined amperage;
- and said electricity-carrying means including a normally-closed heat-sensitive circuit-breaking means and a circuit-breaker circuitry therefor, for opening and thereby breaking electrical-circuit at a predetermined third electrical amperage within a range between said first and second predetermined amperages as a result of an responsive to detected heat for a period of time sufficient for increasingly-hot detected-temperature to have risen to a predetermined circuit-breaking temperature, said predetermined circuit-breaking temperature being below said combustion temperature of said combustible matter and the circuit-breaker circuitry, said heat-sensitive circuit-breaking means being for connecting in electrical series and for intermittently breaking electrical series and for intermittently breaking electrical circuitry of said circuit-breaker circuitry of electricity from said main electrical power-source means to said electric utensil circuit, said heat-sensitive circuit-breaking means being adapted and positioned to become heated by heat from said main electrical utensil circuitry to sufficiently elevated temperature from a sufficient period of time after amperage from the main power-source element is at-least as high as said third predetermind amperage, for said detected heat temperature to reach said predetermined circuit-breaking temperature said heat-sensitive circuit-breaking means including circuit-making means for automatically intermittently closing and thereby making electrical completed circuit whenever after said heat-detected temperature has dropped below said circuit-breaking temperature from a temperature at-least as high as the circuit-breaking temperature, and including an electronic power-delay means for delaying passage of electric current through said heat-sensitive circuit-breaking means and for a predetermined period of time after electrical-contact subsequent to a breaking-of electrical contact by the heat-sensitive circuit-breaking means, said period of time being sufficiently prolonged for the electricity-carrying means to cool-down sufficient as to avert an electrical fire, said electronic power-delay means being mounted in electrical series with said circuit-breaking means, positioned such that electrical flow through said heat-sensitive circuit breaker means becomes possible only after said predetermined period following breaking of electrical circuit by the heat-sensitive circuit breaking means.
