Check the Reasons: Inspect the circuit box again and check whether any of the above reasons tick the current situation of your circuit breaker. Switch on the Devices: You need to test the circuit by switching on all the lights and appliances you unplugged. This gives you an idea of what is causing the breaker to trip.
Solution. Turn off the unit, consult the user manual to find the drain pan, and pull out the pan to check for debris. Clean any grime off and return the drain pan. Check the drainage pipe for cracks or clogs, and use water and vinegar or water and bleach to clean out the pipe. Fully dry the pipe with a clean cloth.

Low Voltage Circuit Breaker. Circuit breakers are the "final control elements" of the electric power industry, akin to control valves in the process industries. They are strictly on/off devices, used to make and break connections under load in power systems. Circuit breakers automatically open when dangerous circuit conditions are detected.
Principle of Energy Storage Switch. The so-called energy storage means that when the circuit breaker is de-energized (that is, when it is opened), it opens quickly due to the spring force of the energy storage switch. Of course, the faster the circuit breaker is opened, the better. This is to have enough power to separate the contacts when the ...
