Install the leakage circuit breaker or the mini-circuit breaker first?
Too many people fake it wrong! Do you want to install the leakage circuit breaker or the mini-circuit breaker first?
When decorating, someone says should install leakage circuit breaker first, and some people say should install small circuit breaker first, after all should install which?
What is a miniature circuit breaker?
A miniature circuit breaker is a protective device, also known as an air circuit breaker that protects against current overload or short circuit. When in use, the CIRCUIT breaker will not automatically trip to cut off the current in the circuit, even if leakage occurs, as long as the current through the circuit does not exceed the maximum current allowed by the CIRCUIT breaker.
What is a leakage circuit breaker?
And leakage circuit breaker is a small circuit breaker with special protection function, special protection function refers to leakage protection, the real professional name is called residual current protection device. In addition to the basic performance of small circuit breakers, it can also quickly cut off the switch when the load circuit leakage, to avoid harm to the human body and adverse effects on electrical equipment, play a protective role.
In real life, the miniature circuit breaker is used as the master switch, and the leakage circuit breaker is used as the branch switch. Therefore, the normal installation sequence is the miniature circuit breaker first, then the leakage circuit breaker. To do this, because if the miniature circuit breaker is installed in the back of the residual current circuit breaker, in case of leakage switch will cut off the power, but a small circuit breaker in wouldn't respond at this moment, that this will lead to great trip happens, simply is the residual current circuit breaker tripping without tripping on miniature circuit breaker.
So what happens when a switch tripping over a level? Once a circuit leakage occurs, the power supply of the whole home will be cut off by the main switch and thus power failure, affecting the convenience of home life, as for other aspects, there is no much impact.
