When selecting a leakage circuit breaker, you should ensure that its rated current and breaking capacity can meet the current carrying requirements of the cable; at the same time, the cable joints should be waterproofed to prevent leakage accidents caused by water ingress at the joints; in addition, the cable laying method should also The requirements for the use of leakage circuit breakers should be met to ensure their normal operation.

2. Compatibility of leakage circuit breakers and switchgear: The compatibility of leakage circuit breakers and switchgear mainly involves the rated current of the switchgear, the selection of short-circuit protectors, and the installation method of the switchgear. When selecting a leakage circuit breaker, you should ensure that its rated current and breaking capacity can meet the current carrying needs of the switching equipment; at the same time, you should select an appropriate short-circuit protector according to the short-circuit protection requirements of the switching equipment; in addition, the installation method of the switching equipment should also be Comply with the requirements for the use of leakage circuit breakers to ensure their normal operation.

3. Compatibility of leakage circuit breakers and transformers: The compatibility of leakage circuit breakers and transformers mainly involves the rated capacity of the transformer, short-circuit impedance, and the protection method of the transformer. When selecting a leakage circuit breaker, you should ensure that its rated current and breaking capacity can meet the current carrying requirements of the transformer; at the same time, you should select an appropriate leakage circuit breaker based on the short-circuit impedance of the transformer; in addition, the protection method of the transformer should also comply with the leakage circuit breaker usage requirements to ensure its normal operation.

4. Compatibility of the leakage circuit breaker and the motor: The compatibility of the leakage circuit breaker and the motor mainly involves the rated power of the motor, the starting method and the protection method of the motor. When selecting a leakage circuit breaker, you should ensure that its rated current and breaking capacity can meet the current carrying needs of the motor; at the same time, you should select an appropriate leakage circuit breaker based on the starting method of the motor; in addition, the motor protection method should also comply with the leakage circuit breaker usage requirements to ensure its normal operation.

5. Compatibility of leakage circuit breaker and distribution box: The compatibility of leakage circuit breaker and distribution box mainly involves the size, installation method and other electrical equipment in the distribution box. When selecting a leakage circuit breaker, you should ensure that its size and installation method can meet the requirements of the distribution box; at the same time, you should consider the impact of other electrical equipment in the distribution box on the leakage circuit breaker to ensure the safety and security of the entire distribution system. Stable operation.

In short, the compatibility issue between leakage circuit breakers and other power equipment needs to be comprehensively considered from many aspects. When selecting and using leakage circuit breakers, one should fully understand the performance parameters and usage requirements of various power equipment to ensure that the leakage circuit breakers can meet actual usage needs, thereby ensuring the safe and stable operation of the power system.
