An arc fault interrupter tester creates a simulated arc fault current through a full wave bridge rectifier, a load resistor and a switch connected in series. These components are rated at currents and wattage well below the current of the simulated arc fault. Thermal management in the form of a temperature...http://www.google.ca/patents/US6876204?utm_source=gb-gplus-sharePatent US6876204 - Test instrument for arc fault circuit interrupters
