1. A method, comprising:
determining, by a microprocessor of a circuit breaker, whether the circuit breaker is performing a task, the circuit breaker including a first firmware data stored in a first location of memory of the circuit breaker;
receiving from a computing device, by the circuit breaker, a second firmware data for storage in a second location of the memory of the circuit breaker;
storing the second firmware data in the second location of the memory of the circuit breaker responsive to the determining of absence of the performing of the task;
setting for execution, by the microprocessor of the circuit breaker, the second firmware data in the second location of the memory responsive to determining absence of the performing of the task;
preventing execution, by the microprocessor of the circuit breaker, of the second firmware data at the second location responsive to absence of completion of a reset of the circuit breaker;
executing, by the microprocessor of the circuit breaker, the second firmware data at the second location responsive to the completion of the reset of the circuit breaker.
