Yes, but keep in mind that if the breaker trips, power is lost to the Smart GFCI Outlet and you will not receive notifications. This is true for GFCI breakers, AFCI breakers and standard breakers. If the Smart GFCI Outlet is installed on a branch with a GFCI breaker, and a ground fault is experienced, both the breaker and outlet will trip, killing power to the Smart GFCI Outlet and no notification will be sent. If the Smart GFCI Outlet is installed on a branch with a standard breaker, and a ground fault is experienced, only the Smart GFCI Outlet will trip, and you will receive a notification.
