Switch what bad things can happen, trip is more common for no apparent reason. Can take trip switch load down the line, change other circuit connected to the load, and see if it is still tripping. If still tripping, it shows that switch is broken. Switch dam. Switch what bad things can happen, trip is more common for no apparent reason. Can take trip switch load down the line, change other circuit connected to the load, and see if it is still tripping. If still tripping, it shows that switch is broken. Switch damage is the best solution, directly buy a switch to change line - take a picture of the old s. Or "overheating". Any circuit breaker with overload protection function, if the current in a circuit is too large, will trigger the overload protection. So after the first trip, should first check the number of load in line, see if there are always too much electricity. Why is also called "overheating"? Because of circuit breaker detect overload, r. An extreme form of overload, where the zero line and the fire line, or the fire line and the fire line are in direct contact, generating a very large current. Short circuit is characterized by: trip immediately after closing, tripping after reset button is not prominent, the screen does not change color (or no reset button or screen) Can cause a sh. If the breaker installed undervoltage tripping device accessories, it is possible to voltage instability in the circuit, automatic tripping. The purpose of undervoltage tripping device, is to prevent the voltage too high or too low, lead to electrical burn. When the users have no way to repair, can consider to tear down a undervoltage trip - but si. Residual current circuit breaker will be in line with the leakage automatic trip, prevent users from electric shock. But not someone get an electric shock is leakage, break, somewhere, in contact with the conductor (the earth also calculate conductor), will be considered by circuit breaker is leakage. After tripping should immediately check lines o.
