Abstract
A method and system are provided for load or branch circuit recovery from a fault(s) on an electrical system. The method and system energize, at a branch device, a branch circuit after expiry of a predetermined disconnection period of time that was initiated in response to a detected arc fault on the branch circuit. The method and system update a data value representing a number of times an attempt has been made to energize the branch circuit in response to detected arc faults on the branch circuit. Upon determining that the data value satisfies or crosses an attempt threshold, the method and system prevent or delay at the branch device the energizing of the branch circuit.
Claims31
A method of load or branch circuit recovery from a fault(s) on an electrical system, comprising:
- energizing, at a branch device, a branch circuit after expiry of a predetermined disconnection period of time that was initiated in response to a detected arc fault on the branch circuit;
- updating, using one or more computer processors, a data value representing a number of times an attempt has been made to energize the branch circuit in response to detected arc faults on the branch circuit;
- and
- upon determining that the data value satisfies or crosses an attempt threshold, preventing or delaying at the branch device the energizing of the branch circuit.
A system for load or branch circuit recovery from a fault(s) on an electrical system, comprising:
- a memory;
- a processor(s) configured to perform or control:
- energize, at a branch device, a branch circuit after expiry of a predetermined disconnection period of time that was initiated in response to a detected arc fault on the branch circuit;
- update a data value representing a number of times an attempt has been made to energize the branch circuit in response to detected arc faults on the branch circuit;
- and
- upon determining that the data value satisfies or crosses an attempt threshold, prevent or delay at the branch device the energizing of the branch circuit.
A non-transitory computer medium storing computer executable code, which when executed by one or more processors, is configured to implement a method comprising:
- controlling energizing, at a branch device, a branch circuit after expiry of a predetermined disconnection period of time that was initiated in response to a detected arc fault on the branch circuit;
- updating a data value representing a number of times an attempt has been made to energize the branch circuit in response to detected arc faults on the branch circuit;
- and
- upon determining that the data value satisfies or crosses an attempt threshold, preventing or delaying at the branch device the energizing of the branch circuit.
