Abstract:
Example embodiments of the invention perform updating of arc-fault detection protection software in a dual function/combination arc-fault circuit interrupter (DF/CAFI) device, without requiring any hardware changes to the device. Maintenance software running in a processor in the device synchronizes downloading the updated protection software as packets of modulated data from a host device, downloaded over an electric power line connected to the device. The modulated data on the power line is sensed by a current sensor of the device and is filtered, demodulated, and sampled by the device. The maintenance software then assembles packets of the demodulated and sampled data and loads them into memory in the device as the updated arc-fault detection protection software.

Claim (Index 10):
A current interrupting device, comprising:\n a current sensor coupled to a sensor input terminal of a current interrupting device, configured to sense data packet information signals provided on an electric power line when the current interrupting device is operating in a maintenance mode, the data packet information signals being carrier signals modulated by data representing component units of an updated arc-fault detection protection software; a bandpass filter and demodulator, configured to receive the carrier signals and output filtered and demodulated data representing the component units of the updated arc-fault detection protection software, when the current interrupting device is operating in a maintenance mode; a sampler and digitizer, configured to sample and digitize the filtered and demodulated data to reproduce the component units of the updated arc-fault detection protection software from the received data packet information signals, when the current interrupting device is operating in a maintenance mode; and a processor configured to validate the reproduced component units of the updated arc-fault detection protection software and load the validated, reproduced component units of the updated arc-fault detection protection software, into a memory in the current interrupting device, when the current interrupting device is operating in a maintenance mode.
