Your circuit breaker does not reset because you may have too many heavy loads connected in containers or electrical sockets on this particular circuit. You may have too many lights on this circuit, or bulbs installed in devices that the rated power is too high.

Now, if you have connected multiple devices in this circuit and you know that the design of the total of these devices is more than 15 amplifiers, then, and only then should you reduce the load in this circuit (disconnect things), restart the circuit breaker once.

Circuit breakers do not reset, because you could have too many heavy loads connected in containers or electrical sockets in this special circuit. a short-circuit. If circuit breakers do not reset, and the circuit immediately, then you probably have a short-circuit state.

Now, if you have connected more devices in this circuit and you know that the total drawing of these devices is greater than 15 amps, then, and only then should you reduce the load on this circuit (disconnect things), reset the circuit breaker once.

If moulded circuit breakers are to be used at least once a year. Routine tests must be carried out every 3 to 5 years. Low voltage circuit breakers must be inspected and maintained every 1 to 3 years, depending on their conditions of use and operation.
