We will see in this article how to determine the Electrical Services in Dubai that cause the electrical installation to trip. However, for your safety, always call a professional. The circuit breaker is an electrical device that cuts off electricity in the event of a short circuit or overcurrent. There are many models, and they are placed on the electrical panel of the installation. When the circuit breaker trips, it is advisable to find the problem before resetting it.
The Role of the Circuit Breaker, All electrical circuits and all devices are necessarily connected to a circuit breaker in the electrical panel which protects them from short circuits. A circuit breaker works like a switch, but trips automatically.
How Control Short Circuit?
According to Electrical Services in Dubai: When a short circuit occurs, the coil present in the circuit breaker detects the overcurrent and creates a magnetic field that opens the contacts of the circuit breaker. When all goes well, current flows through the circuit breaker uninterrupted. The circuit breaker also protects against overloads. If exceeded, the conductors heat up and the risk of catching fire increases.
How does a Circuit Breaker Work?
In a dwelling, the meter is connected to the general circuit breaker which protects against overloads and short circuits. Divisional circuit breakers are connected to each location of the dwelling. If too many devices are in operation simultaneously, the power subscribed by the subscriber may be exceeded and lead to a general outage.
The Role of Differential Circuit Breakers
There are also differential circuit breakers that protect people when they are in contact with metal masses that are accidentally energized. If the masses of the devices are correctly grounded, then the differential will detect the difference in intensity and cut the electrical circuit. More or less sensitive, they will perfectly protect goods and people. Electrician Charles et fils recommends that you check the correct operation of the circuit breakers once a year.
How many Circuit Breakers are needed in an Electrical Installation?
What the NF C 15-100 standard says about circuit breakers, As we have seen, circuit breakers are essential in the context of a residential electrical installation: they are responsible for cutting off the Current in the event of overcurrent or short circuit, in order to protect the connected devices. The choice and use of circuit breakers are regulated by the NF C 15-100 standard, which guarantees an optimal level of safety for your domestic electrical installation. The maximum current of the circuit breaker is determined according to the type of circuit to be protected, therefore,
- 16 A max circuit breakers for lighting and socket circuits, for a maximum of 8 light points or 8 sockets.
- 20 A max circuit breakers for circuits combining up to 12 sockets or for sockets dedicated to the kitchen.
- Circuit breakers between 16 A and 32 A for specialized circuits. The circuit is then dedicated: to rolling shutters ( 16 A circuit breaker ), household appliances and electric heaters up to 4.5 kW ( 20 A circuit breaker ), and hob ( 32 A circuit breaker ).
How many Differential Switches are Needed for a Dwelling?
- The N FC 15-100 standard stipulates that it is necessary to install:
- At least 2 differential switches: the first type AC, and the second type A, both with a sensitivity of 30 mA maximum. A differential switch must be installed for a maximum of 8 electrical circuits (with a branch circuit breaker for each of these circuits).
- To ensure proper operation, the circuits including Sockets and lighting must be distributed under at least 2 differential switches.
- Also, some appliances must be protected by a type A differential switch. For example, the hotplates, the washing machine or the socket for recharging an electric vehicle must be part of the circuits secured by a differential switch of this type.
- Finally, everything else: lighting, sockets, USB sockets, fridge, oven, dishwasher, water heater, roller shutters, ventilation, etc. – can be protected by an AC-type differential switch.
Meters that are too old are more likely to Trip the Electricity
If your meter is too old and therefore exceeds the standards in force, this may be the cause of the electricity problem that cuts out. Having no power to meet the electrical needs of your home, the electricity, therefore, cuts regularly. If so, you should consider installing a standard electrical panel as soon as possible.
There are two types of circuit breakers:
- Protective circuit breaker, which cuts off power when it detects an electrical overload, such as connecting too many devices at the same time.
- The GFCI has the added function of protecting your home circuit. Therefore, if it detects a short circuit problem or a leak in one of your devices, it will also cut off the power.
- The power of the meter is not sufficient and causes the electricity to cut out.
- Indeed, if your supplier contract is 3 kVA (minimum power) and you need 6 kVA, then it is normal for your device to trip. It is therefore recommended to contact your electricity supplier to modify your subscription contract upwards.
- If your electrical installation trips too many times, it is recommended to call a professional electrician to solve the problem. Electrical standards are now very strict to best ensure the safety of people. Only experts have all the skills to properly adjust the repair table according to your needs.
