Abstract
An electrical safety product circuit topology and its equivalent variations for sensing, control, and reporting of household AC wall current, voltage, power, and energy use, and status of its Ground-and-Arc-Fault-Interrupting internal circuit breaker, is presented herein. The architecture includes any choice of telemetry platform, presumes a plurality of its kind join a wireless network with a plurality of other products endowed with the same platform faculty. Topology variations claimed include current and differential current sensing by toroid or other transformer or by Hall semiconductor means, and include fault condition recognition by microprocessor-based algorithms, or by various analog circuit or digital signal processing (DSP) means. Embodiment variations claimed include any modular circuit breaker panel component form factor, any in-wall outlet or switch-box form factor, and any plug-in AC socket module, in-cord module, and outlet strip form factor.
