A 15 amp breaker trips when the microwave and Keurig (or a space heater) are used at the same time. Dormitories and some hotels use "micro-frigs in rooms. They shut off the frig when microwave is in use. The device I am seeking would do the same thing not allowing the Keurig to be used when the microwave is in use. I am considering taking some load off the circuit or replacing the breaker with a 20 amp one, but the device I am seeking would be best. Any input would be welcome thanks
