What switch for the house should I buy?
hace 5 años
hace 5 años
Buy a small 2-story house, in the kitchen is the light switch, which is an old one where you used to put two lead wires next to each other to which copper wires have been adapted, it worked until a week ago that apparently one of the screws has been stolen and does not fit one of the cables, and it turns out that there is only light in the outlets but not in the spotlights, then I started looking for thermal switches to make the change, but I don't know which to buy , since there are some that say 10 A, others 40A, 60A, and some more rare that say 2 X 10A, 2 X 40A
Having a switch that activates the general energy of the high Amperage house. Does it mean more electrical consumption, or some waste? Which thermal switch should I buy?
How is it different to install a 10A switch with one that is 2 x 10A ??

It is the same colleague, one tells you that it is 10A and the other that it is 2 takes a double take of 10A so you can use it with 10A is more than enough unless it is fence to use electric cooker

Checking the previous switch I read that says "30A", of course I consider that the cable should correspond to that Amperage but, my doubts would be, what happens if I put a 63A Rail Type Switch, or if not a 2x40A Rail Type Switch? Would there be a risk of something? Do both switches serve exactly the same? or one is safer than the other, some difference maybe.

As the colleague Ricardo mentioned to you, you cannot place any magnetothermal measure, everything has its measure and its why
You cannot choose one of 63 instead of one of 40 or 25. Each responds differently.
the risk of placing a thermal larger than what is applicable is that when an eventual failure occurs, it will not be cleared in time and damage to the affected circuits will occur that will be of different severity Insulation failures , leaks and extra consumptions
Short circuits,
Line heating, fire
Risk of indirect contact and death by electrocution
The choice responds to only one thing, the measure of the cables to be protected
As you can see, you have separated what are the lighting currents, so what I recommend is the general key to replace the 30A fuses, a 25A thermal magnet. then the circuit of shots one of 16 and the lighting one of 10
The difference between saying 10 or 2x10 can be simple syntax or none. The saying of 10, in fact what it expresses is any of 10A and the number of poles is not specified, so to express correctly it should say unipolar of 10, or bipolar of 10 etc.
By saying 2x10 what is being expressed is a 10-pole or two 10A bipolar.
In your case you will know if you must place one or two poles, it depends in part on the regulations of each country, in Argentina for example bipolar are mandatory for single-phase circuits and the neutral must also be protected, instead other countries such as Mexico, use unipolar and the neutral is direct without any protection
Since you surely don't have a differential switch, you must incorporate it.

Thank you very much for your explanation, it was very clear. Now I have learned that more Amps does not mean that it is better, since the switch has to be able to be deactivated so that no more energy passes than the cables resist. And reading Ricardo and other sources, I see that according to the thickness of the cable the amount of Amps should be considered. Here is used two-phase, I estimate that my cables are 2.5 mm, in the bathroom there is a switch for the heater that says 20A. I think I'll opt for the 20A switch, I hope it's enough because I use electric cooker.

Hello
The thermal switches protect the cables, so each thermal must correspond to the diameter or caliber of the conductor to be protected. It must always be lower than the cable limit.

It seems that you were not interested in the attachment? Not even what I explained. If you have a thermal of 30A you cannot put a 40A because you are not going to protect the cables, at most you can put 2x30A or smaller, never larger than what the cables support. It is understood? By putting a larger thermal what you get is that, in case of a problem, the cables are burned first and hopefully then the thermal skips. Regards

It is not that I have not been interested in your PDF, only that they are terms that I have never seen, so it did not help me to orientate myself, and regarding your first explanation I understood what you said, to find out, etc ... but not the breaker apart, because here I only see an old lever that barely reads 30A ... understand that I am looking for information to learn, out of curiosity and knowing which one to buy. In your last explanation, I just found clear answers about my question. What is the difference with the keys, the Amps and what can happen. I will try to see the cables I have to find. Grax

I have tried to see how much the cables are but I do not see anything written, it will be because of the colors I suppose, one is yellow and the other blue. The old switch says 30A and to the right quite blurry it says 250V seems to me. Now in the online store I am seeing that there are 32A, not 30, I wonder if these 2A extras will burn my cables, since you indicate that it must be the same or less. It seems that a single lever that used leads has been lighting the entire house and feeding outlets for years.

In the pdf you have the outer measurement of the cables, supposedly you have 6mm2 and 30A thermal cable would be the correct one and the 32A would also go only more tightly and taking into account that they are not new cables I would not risk and place 25A. And considering that this thermal is only for lights (you say the shots work) also 20A would be correct

You should first find out what gauge is the cable your installation has.
It depends on the gauge of the cable is that you are going to choose from how many Ampers your Thermal Magneto Breaker is.
It should be at least one double as the main one to cut the lines that come from the connection and then separate the internal circuits with other Breakers apart, one for the luminaire, another for the current sockets and failing that if it has other separate circuits.
Usually the kitchens and washers have a separate circuit because they are the ones that consume the most load.
