Electric Cooker Installation

Hello friends. I have to leave the electrical installation planned for an electric kitchen in an apartment that a priori does not know what device will be installed. I was seeing some models of kitchens that have 1,500 W and 2,000 W burners so I estimate that with a 2x2.5mm2 and 2x16A thermomagnetic line it would work well. However, that would be when the kitchen is using only one burner. I have also seen that it is possible that some kitchens reach a consumption of almost 7 kW which would give me a current of almost 32A and therefore I should place a TM of 2x32A and 6mm2 conductor. According to their experience and taking into account rational consumption, what line would they leave for the kitchen? TM of 2x32A and 6mm2 line? TM of 2x25A and line of 4mm2? or TM of 2x16A and 2.5mm2 line? I clarify that the installation is single phase and the department has small dimensions. Thanks in advance. Regards.

HOW ARE YOU? WE KNOW THAT BY THE CONSUMPTION OF THIS TYPE OF ARTIFACT IS NORMALLY DESIGNED FOR THREE-PHASE FOODS, WE TAKE INTO ACCOUNT THAT THE MONOPHASIC METERS SUPPORT A CONSUMPTION OF 40 AMP APPROX, WHAT I WOULD LIKE TO LIMIT THE CONSUMPTION FOR NO MORE THAN A TWO TERM THAT SHOOTS IN CASE OF PASSING + N WITH CONSUMPTION, IT IS NOT A GREAT SOLUTION BUT IF A WAY THAT SOMETHING BAD DOES NOT HAPPEN. REGARDS.-

As a first step, you have to see the caliber of main and sectional line cables, with which appliances the property has, in order to determine well and give you a correct report. Comment

Hi. Thank you for your response Carlos. The line that reaches the board is a 2x6mm2 sintenax. The board has a Thermomagnetic 2x40A circuit breaker 2x40A and sensitivity 30mA. Then I have three circuits. One of them is from sockets whose line is 2x2.5 mm2 and TM of 2x16A; another is lighting with TM of 2x10A and finally I have a line of 2x2.5mm2 and TM 2x16A for a small air conditioner (at most it will be 3,000 fridges).

If you are not going to bande with the use of the kitchen, I would put a 16A thermomagnetic, and 2.5mm cable to feed the kitchen. With the 4mm and thermal 25, you put it very close to the installation and you will reduce power if in the future it has aggregates. Electric cookers consume a lot, but at intervals, they heat and cut, it is not a constant cost. You have to explain to the user that he cannot turn everything on at once. In my house, I had to set up an electric cooker because they cut my gas, after rethinking the main and sectional line that was not ready.

In my case I limited it with 10 A thermal and 2.5mm calbe to feed it. If they are banded, the thermal jumps. Just explain that they can not turn everything on at once. However, if they want to use it fully, you have to start thinking about three-phase.

Carlos Caballito, you confirm that the 10A tertmica. Has the load of the kitchen that you installed in your house limited you? Sorry for the interference, but it is a very important fact, thanks and greetings to both, because Eespejo is the owner of the query, thank you, alualo

Hello I would place 25 thermal and 4 mm² conductors that assures me that this family will have the equivalent of oven + 1 burner or 3 burners to use without problems Advice: The facilities must be adapted to the maximum declared consumption, it should not be speculated that such a family will take care not to light 2 burners at the same time because that will not happen, when they have a party, meeting, entertainment or whatever and they have to cook several hours, they will cook in the shortest possible time and they will forget the promise made to the electrician .... What if ... when they cut the thermal they will remember but not in the best way .. It will be a poor installation. The other thing to evaluate is the main and sectional line if it is sufficient or must be increased in section. Not only for consumption but also for voltage drop, if it is necessary to change it is changed, but everything must be prepared to support the load and if it exceeds 10 kW and requires three-phase, they must make the change, that will depend not only on the kitchen but also on the other loads, especially those of high consumption and that it is not possible to avoid. Example, hot water tank Regards

I have definitely realized that it is not a topic to deal with so superficially. They are right in each of the things they have told me and obviously the caliber of the line will depend on the lifestyle of the people who live in the apartment, even if it is small. I'm going to investigate a little more about the artifacts there will be and then I tell them. Thank you very much for your answers.
