How many watts can a 15-amp breaker hold?

A 15-amp breaker can hold a maximum load of 15 amps or 1,800 watts (15 amps x 120 volts = 1,800 watts) for a sustained period of time without tripping. However, It's important to note that electrical circuits should never be loaded to their maximum capacity for an extended time as it can cause overheating and potentially start a fire. It's always a good idea to consult a licensed electrician if you have questions or concerns about your electrical system.
