The answer to 'why is my carbon monoxide detector tripping breaker' is that a tripping breaker is a common symptom of a malfunctioning carbon monoxide (CO) detector. This can happen when the detector senses dangerous levels of CO in the home and trips the circuit breaker to cut power as a safety measure.
Some common causes include a faulty detector, a problem with the wiring, or high levels of CO from a malfunctioning appliance or other source. It's important to address the issue right away, as a tripping CO detector indicates a potentially hazardous situation that needs to be resolved.
