Matias.......A circuit breaker is an over-current protection device and as such is not designed to be used as a daily use switch. Yes, flipping the circuit breaker off kills the power, but continuously flipping the circuit breaker off and on can impact the over-current devices ability to properly perform its designed task.

There are certain circuit breakers that are designed for switch duty and are designated as such with the letters SWD, but unless your specific circuit breaker is a switch duty rated over-current device I would not recommend using it in the manner you described.

Should a Circuit Breaker be used as a Switch?
