Abstract:
1. An electrical safety device comprising: at least one current sensing device configured to measure a current on at least one conductor of an electrical wire connected to a load side of the safety device; at least one voltage sensing device configured to measure a voltage associated with the safety device; and at least one processing component configured to (i) receive the current measurement and the voltage measurement, (ii) identify, based upon the current measurement, an overcurrent event, (iii) after identifying the overcurrent event, compare the voltage measurement to a stored voltage value, (iv) determine, based upon the comparison, a difference between the voltage measurement and the stored voltage value, and (v) when the difference satisfies a threshold condition, direct at least one relay to be opened to discontinue provision of an electrical power signal onto the electrical wire.
