The main function of the circuit breaker is to protect the network from overloads and short circuits. Often situations arise when the owners of apartments and private houses have to solve the problem of why the machine knocks out in the shield and establish the reasons for such operations. Usually the whole thing is limited to replacing the machine with a higher denomination. However, such actions do not effectively resolve the issue, since the operation will occur already with an increased load on the wiring. As a result, home network lines can burn out and fail. To take the most effective measures, it is necessary to know the reasons that cause the machine to operate in each specific case.
Knocks out the machine in the apartment of the reason
The most common reason for the operation of the machine is considered to be the fulfillment of its main function - to protect electrical wiring from overloads. Each model is distinguished by its own tripping, ranging from 6 amps and up. When several powerful devices are switched on at the same time, the current setting is exceeded and the protective device trips. Most often, overload is caused by a washing machine, water heater and other household appliances.
This problem can be solved in various ways. First of all, you should not allow the simultaneous switching on of powerful equipment. In the presence of high-quality wiring with copper conductors and a cross section of at least 2.5 mm2, it is allowed to install a more powerful machine.
In some cases, when the machine knocks out, the reasons may be related to faulty household appliances. Therefore, the machine starts to knock out when it is turned on at the same time. In the presence of a serious breakdown, even devices such as a kettle or a computer can have a negative effect. To check this fact, you should turn off all the devices one by one and see how the circuit breaker behaves. If it works normally, then the reason lies in one of the household devices, which, when turned on, will trigger.
A fairly common cause is a short circuit in the wiring. In some place, the phase is in contact with zero and the machine performs a second function - it protects against a short circuit by triggering.
You can determine why the machine knocks out in a simple way. All devices must be turned off, and if the machine still works, then the wiring is faulty. It is recommended to start the test with sockets and switches, after which junction boxes, lamps are checked, and at the very end, the wires are checked. Usually, the presence of a short circuit is determined using. However, in particularly difficult cases, it is recommended to be able to accurately and quickly detect the malfunction.
Sometimes unplanned triggers occur due to the poor quality of the machine itself. The fault can be identified by replacing the device with a new device. In most cases, this allows you to effectively solve this problem.
When you turn on the light knocks out the machine
Quite often, at the moment the light is turned on, the introductory machine knocks out, and the entire electrical network is de-energized. This malfunction can occur for various reasons, and the most important of them is a malfunction in connecting the chandelier, which uses conventional incandescent bulbs with an E27 base. To identify a possible malfunction, you need to unscrew the lamps and inspect their bases for a short circuit.
At the connection point of the chandelier, the contact burns out, which causes a short circuit and operation of the protective device. Sometimes it's all about the 12 volt transformer included in the design of the chandelier.
In some cases, the operation of the circuit breaker in the shield occurs at the moment the light bulb burns out. The machine knocks out under the action of a short-term overload. With a low rating of 6-10 amps, there is a high probability of unplanned operation. This effect is completely devoid of fluorescent and LED lamps.
Constantly knocks out the machine in the shield
Quite often, the owners of private country houses and apartments wonder why the machine knocks out in the shield without load, in the absence of visible reasons. In addition to the factors already considered, this situation often occurs due to overloads in the outlet network.
When drafting and installing electrical wiring, it is impossible to establish with absolute accuracy the degree of load on each group of outlets. Usually 3-4 outlets have a separate circuit breaker. However, in the presence of a powerful protective device, the current rating of the connected sockets can be significantly lower.
In such a situation, an overload will certainly occur, especially if an iron, stove, microwave and other powerful equipment are simultaneously connected to one group of outlets. As a result, there is an indispensable operation of the circuit breaker. It is possible to exclude such cases by evenly distributing a powerful load between several socket groups. If this is not possible, several consumers with high power should not be included in the electrical network at once.
Sometimes it happens that the machine knocked out and does not turn back on. Here the reason may be in the thermal release, which is very hot. To turn on the device again, just let it cool down, and it will work again in normal mode. The machine is often triggered by a faulty device that consumes high current. As a result, the network is overloaded and the circuit breaker is knocked out. The solution to the problem, as already noted, is to turn on the devices one by one until a faulty one is found among them.
It happens that the machine itself is not connected correctly. Wires that are loosely tightened in the terminals lead to heating of this place and the operation of the thermal release. The reason is visible to the naked eye, when not only the insulation of the wire becomes burnt, but also the body of the device.
