1. The insulation of the electrical equipment itself is damaged, which causes the leakage switch to trip when the electricity is used;
2. The wet insulation strength of the line is reduced, which causes the leakage switch to trip when it is not using electricity;
3. Accidental personal electric shocks cause the leakage switch to trip and trip;
4. Incorrect wiring during construction and installation, resulting in leakage switch fault tripping during power use.
1. The power of the electrical equipment is too large, exceeding the load capacity of the leakage protector
2. The circuit is short-circuited or leakage, check whether the circuit is damaged.
3. If the electrical equipment is leaking or damaged, use a multimeter to measure whether its insulation is normal.
4. The operating environment is too humid.
5. The leakage circuit breaker is damaged.
Causes of tripping of household leakage circuit breakers1. Poor installation
2. The leakage switch does not match the load
3. Leakage or short circuit of electrical appliances or lines
4. The power input line voltage is too high
5. There is a problem with the quality of the leakage circuit breaker
6. Wiring error of leakage circuit breaker
7. Leakage of electrical equipment
8. The N wire and PE wire on the socket are connected reversely
9. The line is damp, causing leakage and tripping
10. The N wire of a certain lamp in the lighting circuit is taken from the socket circuit
The method of eliminating the tripping of leakage circuit breaker1. Dividing line elimination method
If the leakage circuit breaker trips, you can disconnect the branch circuit of the power grid first, and only carry out the power transmission test on the main line. If the main line test is no problem, then the branch and terminal lines are tested and eliminated in turn to find the fault point.
2. Visual inspection method
Carry out a careful inspection of the protector and the protected line equipment, such as the corners, branches, crossovers and other complex and prone fault points of the line to find out the fault points.
3. Numerical comparison method
You can also use an instrument to test the line and compare the measured value with the previous value to find the fault point.
4. Trial delivery method
Finally, troubleshoot the protector itself. It is recommended to cut off the power first, remove the transformer side lead of the residual current protector, and then reconnect the protector. If the protector still fails to operate, it means that the protector itself has a problem and needs to be repaired or replaced. It cannot be put into operation. If there is no problem with the protector, you need to find the switchboard and wiring. Check whether the insulation of each electrical circuit and instrument is good, etc., and check them one by one until the fault point is found. If it is really unclear, please ask professionals to come to repair it.
