If it was designed for a lower load during installation, but over time the number of consumers has increased. If the circuit breaker regularly trips, do not replace it with a more powerful one. The wiring may melt due to overload. The best solution is to identify the section subject to increased load and make it a separate line w
ith its own circuit myanmar email list 175737 contact leads breaker, increasing the cross-section of the wires.
If you doubt that you have correctly determined the power and class of the input circuit breaker, contact a professional electrician. Restoring melted wiring costs more than his services.
The circuit breaker To sum it up:
1. Short-circuit current. The PUE rules stipulate that circuit breakers with the highest breaking capacity of less than 6 kA are prohibited. If the house is located next to a transformer substation,
you need to select a circuit breaker that how much does it cost to retain a customer? operates at a maximum short circuit of 10 kA. In other cases, a 6000 Amp device will do just fine.
Nominal current The circuit breaker
This characteristic displays the current value above which the circuit will be disconnected and the electrical wiring will be protected from philippines numbers overloads. To select the appropriate value, you need to start from the cross-section of the home wiring cable and the power of the electricity consumers.
Tripping current. Along with the operating current
It is necessary to select its rating according to the tripping current. To prevent the circuit breaker from tripping, perceiving the engine switching on as a short circuit, it is necessary to correctly select the class of the switching device.
4. Selectivity, i.e. disconnection in an emergency situation of only a certain, problematic section, and not all the electricity in the house. Here it is necessary to select the ratings in accordance with the service line. The rated current of the input switching device must exceed the value of the operating current of all the circuit breakers in the panel.
