WHY DOES A CIRCUIT BREAKER TRIP AND HOW TO PREVENT IT?
Everywhere with an electrical installation must have a circuit breaker (fuse). The basic function of a circuit breaker is to ensure safety by disabling the electrical installation when current exceeding a certain value passes through the circuit. When the voltage level rises above a certain unit, our devices burn out and short-circuit, leading to the situation we know as a “tripped breaker.” Although a tripped breaker is a frustrating situation, if it does not occur, the loads connected to the circuit can be seriously damaged. However, if necessary precautions are not taken, the circuit breaker may become unable to fulfill its function.
Why Does a Circuit Breaker Trip?
An electrical circuit breaker is essentially a safety tool. Although there are different types according to their areas of use, their basic working principles are the same. When the maximum current value is exceeded, the breaker disables the electrical installation. The situation commonly known as a “tripped fuse” is essentially the fulfillment of this safety function.
Maximum current values are indicated on circuit breakers according to the ampere measurement unit. When the maximum value on the device is exceeded, the electrical installation in that area is disabled. In this case, the breaker prevents the current flow by opening the circuit and protects the installation system.
How to Prevent Frequent Tripping?
First of all, the circuit breaker must be selected according to the current capacity of the installation in the area. For example, while 16 amperes is considered a maximum value for a house, it might be a routine load for a larger area. In this case, using a 16-ampere breaker will cause the installation to constantly shut down. Therefore, the electrical breaker to be used for the installation should be selected considering both routine and maximum values.
Residual current devices (RCD/GFCI) can also cause power cuts. In the event of any leakage in the apartment, it is inevitable for the residual current protection to activate. In this case, the leakage in the apartment must be found and repaired.
If the breaker trips when certain tools are running or when multiple tools are running together, we can understand that there is a problem with the electrical installation. In such cases, the installation should be renewed, and voltage damping devices should be used.
What Should Be Done to Protect the Electrical Breaker?
The circuit breaker can be damaged in certain situations. The aging or burning of breaker connections and cables, or the exposure of the breaker to overvoltages, causes malfunctions. If the tripping is followed by a smell of burning, charring, or a small explosion, this indicates that the breaker connections are old or damaged.
However, the real danger is when circuit breaker components are damaged in a way that is not visible from the outside and the breaker fails to disconnect. In this case, there will be no way to protect the installation when ampere values are exceeded. It should also be noted that if there is a problem in the installation that could lead to such events, changing the breaker will not help. To protect the breaker by preventing high voltage in the apartment, it is necessary to block the effects of overvoltage.
High voltage originating from internal circulation or external sources, such as lightning strikes directed at the grid, must be prevented from affecting the installation and passing through the breaker. This prevents certain devices from wearing out the ampere limit and causing a tripping situation.
