We have probably all experienced the moment when we turn on too many high-current devices, such as microwaves or coffee makers, and the power drops out. When we overload a circuit a breaker is designed to trip and turn off the power to the offending circuit branch. This helps prevent circuits from overheating and potentially causing a fire.
Even though these events happen, it’s important that we do not ignore them. If a breaker is failing repeatedly this is a clue that something is not right. 
What can you do?
- Understand that breakers panels help protect buildings from overcurrents (too much current).
- A breaker should not be reset if you do not know why it has failed. If a breaker is repeatedly tripping, assume something is wrong and get assistance.
- If on campus seek assistance from Facilities Services.
