Doubt in section of cables for department ..
hace 5 años
hace 5 años
Hello, good morning everyone, thanks for all the information you provide us.
I wanted to consult to pass a section of cables to an apartment, in the back of my house ... 20 meters away
My doubts are the following ..
I have to connect from the 25A therma that goes to the house and is in the pillar of light to go out to the apartment and make it independent of the house? ....
With which section of wires would you leave from the pillar with 4mm or 6mm and get to the thermal and circuit breaker of the department?
Is it okay to buy brand of cables KALOP?
(I will only have a refrigerator, TV and washing machine ... but the plugs and spotlights in total are 60 square meters of housing).
Thank you very muchssss

Hello
With a cable of 4 mm 20 meters away from the pillar, you will have enough for what you mention, a 60-meter type house covered with all the comforts without high consumption electrical appliances (neither hot water tank, nor shower, nor stove, nor air conditioning electric), at most you can have an air conditioning of 3000/4500 refrigerators; This, without having problems of voltage drop.
Anyway, always, over time there are extensions, where the conford is improving, and along with it the consumption, so if you can afford it, it is planned and placed a 2 x 6 mm cable.
The Kalop brand is not one of the best or the worst, but this is not a critical point if you handle well-known brands.
Doubts, ask.

Thank you very much for your prompt response,
I ask you which cable brand you recommend, since I decided to buy a 6 mm section cable to think ahead and prefer to spend twice as much but stay calm.
I bought Kalop cables because I had bought cables from an unknown brand and Inexpensive and the house almost burned ...

Hello
The highest quality cables, which I use in all the works that I can, is the prysmian (formerly Pirelly) has double insulation and is lubricated, in its absence the INSA, or the Fonseca (in that order), these are of very good quality. then a little further, the Kalop`, copper, etc.

Hello
If the apartment is independent of the existing house (I understand that yes) it would be convenient to place another thermal in the pillar.
That way the facilities would not be dependent.
A thermal (existing) for the house and another for the apartment.
In case of repair or any inconvenience you can cut your thermal without leaving the other unit without light. Otherwise, any inconvenience in the house would not leave you without power in the apartment.
As for the measurement of cables I share the idea of a nastor; If you can put 6mm thinking about future extensions it would be the best; but you would have to put on the pillar a thermal of 30 or 32 A

Every supply must have a general switch that covers absolutely everything
If you set a separate thermal you must not dispense with a general switch
The fact that it has 6 mm² cables does not require the installation of 32A thermal. In fact, observing the above, it may be necessary for the thermal section to be smaller (if selectivity is required)

Hello Gustavo. I understand that you must install a sectional board inside the apartment. And also as if they were two independent meters. The 6mm and 32A thermal was thinking about future extensions. Of course the problem is going to come when splitting the bill. I think .......... Regards

okay. Richard
Question ... I thought to leave from the thermal pillar of light 25 A that goes to the house and splice with that same to the department being independent of each other, because they would only share the thermal of the pillar of light and nothing on the board that is inside the house ... that's what I thought ... because I will be all the cable connection channel from the house to the bottom of the apartment ..
Now you tell me that it is better to put two thermals behind the pillar ... that is, I connect from the wiring that comes from the LIGHT METER there I put two thermals ... would it be?
hace 5 años
another question ... if I have a thermometer of 25A and NOT of 32A in the pillar of light as Ricardo recommends me, I would not take care of the 6MM cables anymore, leave the 25A thermals and I would go all the more forgotten? electricity with basic connoisseurs ... coomo says ELEKTOMAQ
and I'm also going to put a board in the apartment with 16A thermal and 32A circuit breaker ..
and you will not see two METERS only one

Mauro: The issue of independent thermal is for the two houses to be independent, but one detail that I did not take into account is that there has to be a general key by regulation (as elektomaq pointed out). That general key will depend on the total consumption of the two houses. To your question about protecting the 6mm cables, they support 35 A and the thermal protector must be of less value. but not less than the estimated consumption. We previously suggested 6mm and 32A protection for future extensions. Greetings and thanks Gustavo for the detail.

ok .. thank you both for answering me ..
my consumption from home is the same as the apartment ... both have the same electric things
a plasma TV, a refrigerator with freezer, a microwave, automatic washing machine, standing fan, iron although not used ... I only have that
hace 5 años
ok .. layers that express me badly in the previous comments ...
I would connect from the thermal that is in the pillar of light to the department that is 25A the same one that goes to the house where it has inside this other 16A thermal and its 25A circuit breaker, the same would put in the department ..
if this thermal would not support the consumption of the house and the apartment that is the pillar of light, you recommend that I put a thermal of 32A so it would be ..
I also have an extractor hood

and I put javelin with 2.5 cable ... any recommendation to install it ???
hace 5 años
and I do not divide it into two circuits as I have the house in front too, in a single circuit ... I never had problems with this way of placing ... I understand that it is better to put two circuits ... what happens is that I do not already input it I did so, and I already put the whole corrugated pipe through the house in this way ... surely the next house I do if I am going to divide it with independent circuits one for the lights with its thermal and one for the shots with its bipolar thermal also
hace 5 años
Now I am finding out to put the pirelli prisman sea line cable that they say is the best because the kalop does not recommend it to me, they also tell me that I have to put a 32A therma on the pillar of light because outside the house I have a lamppost of the municipal lighting and that influences the light that goes to my house .. is this ??

In your case, the option of leaving with a single line from the pillar to the first house and from there splicing to the second is not the most recommended.
It is necessary that you know first of all that to take food for two houses from the same supply, it is not allowed, each house must have its supply, that is its meter
Having clarified this point we go to what I think is the best option:
10 mm² cables exit the meter to the main board (on the pillar)
Hence a general thermal of 40A
It is divided into two circuits with 10 mm² cable that enter two thermal (on the same board)
Each of the 25A thermal
From the thermal 1 (front house) out 4 mm² cables
From the thermal 2 (back house) 6 mm² cables come out
This cable measurement difference is only to ensure the lowest possible voltage drop
At the entrance of each of the houses there will be a sectional board
both boards with a 30mA differential circuit breaker (minimum 25A, recommended 40A) as a header and hence divided into the different circuit thermal (minimum recommended 2 circuits per house up to 60 mts²).
Leave room on the boards to incorporate at least one more thermal in the future
All thermal must be bipolar
Each of the sectional circuits (conductors that arrive to each dwelling) must go in different pipes. In this case, the unipolar conductor with pvc insulation IRAM nm247-3 is the one indicated, the kalop is of good quality but not the best. This type of cable is only admissible under pipe. The channeling if it is under roof can comply with degree of protection ip40, however if it is outdoors it must be ip65
If they go without a pipe, they must go over a wall over 2.50 meters high and the cable must comply with IRAM 2178 (in this case the unipolar pvc kalop does not work). You can also go underground at 70 cm deep with IRAM 2178 cable
if the laying is aerial, it must be pre-assembled or another cable with XLPE insulation (cross-linked polyethylene)
The line that goes to the back house should not pass through the inside of the front house, ensuring access to any point of the house
Do not forget grounding, which can be one for each home or one for both (in your case the most recommended is one for each home)
So there is what I would do to achieve the best results
Although splicing from house 1 to take to house 2 is the easiest, it is not recommended for several reasons, for example, there are no independent houses. The cable to be used should be at least 10 mm², which complicates the installation and makes it more expensive
Any questions comment here,

perfect..elektomaq..thanks for taking the time to answer everything ... and explain everything so perfect ..
Now I ask you the question ..
my idea was, from the meter or pillar of light, to put another 32A thermometer so that they are independent one house from another, since the same house is the owner from the front with the back department ..
from there put 6mm line cable to the apartment inside the house to the bottom by pipe ... until the sectional board a 40A circuit breaker and a 16A thermal for the whole house also plugs as lights and not divide it in two

The thermal of 32 is fine but I did not understand in another comment what you put in the street lighting
The wiring is not the right thing but it does not mean that it will not work for you or that you will have problems.
When the installation is not adequate it does not mean that the next day everything is founded and that you have had it for a long time so it does not mean that you are free to have problems. Remember that a failure does not occur in years, occurs in tenths of a second and the advice is not to avoid problems but to minimize their consequences and better use of electrical resources

Now I am finding out to put the pirelli prisman sea line cable that they say is the best because the kalop does not recommend it to me ,,, they also tell me that I have to put a 32A therma on the pillar of light because outside of the house I have a lamppost of the municipal lighting and that influences the light that goes to my house .. is this ??
I can't find the cable you told me
hace 5 años
I still don't buy it ... that's why I asked you if Pirelli Priyman is ok or I'm looking for another one I'm trying to buy the best if possible ... I buy 6mm then with that it would be covered ... and the light post told me the of the alarm that having the lamppost glued to my pillar of light the lighting of the same influences the general thermal of the pillar .. I iva apiner 25A and now he told me to pjonga 32A so that he does not jump
hace 5 años
if I connect two 32A bipolar thermals from the meter ... light pillar
one for the house and another for the independent department (the owner of the two houses is the same person) and from there I divide each house with its thermal and circuit breaker for each one ... of 16A and 40A
I wouldn't be doing the right thing ???
With 6mm cables I reach the apartment and what brand would be the cables?
Can I pass them inside the house until the end of it covering it with cable channel? and then outside the house take it by pipe to the apartment and entering the board of the same?
sorry

Mmmmm no ... it has nothing to do with it. Same with 6 mm² for both houses, better than 32
If you ask for "pirelli prysmian" it is very possible that they will tell you no
It's Prysmian Superastic jet / flex
Pirelli doesn't exist anymore
It depends on where you are, you might not get it even if it is a multinational brand

Hi, I am from Argentina and I wanted to buy good cables, as I bought KALOP inside, now I want to buy the best one and everyone tells me PIRELLI ... I DO NOT HAVE MANY OPTIONS ... I buy it for free market
I am going to buy .. Unipolar cable 6mm Prysmian Pirelli superastic flex ..
your explanations of how to do it helped me a lot ...
I ask you a question can I put the 6mm cable by channel cable and then by corrugated pipe?
Do you have to go the cable alone or can you share with more cables? not to make another hole in the wall
hace 5 años
Thank you very much for all the information ... everything you told me is useful and I have it in mind to do the installation ... since for me it is useful people who help others who do not have so much knowledge

through the pipeline goes neutral phase and earth all together. If there are other circuits it is better in another channel
The interior channeling in sight can be cable channel or rigid pipe (not corrugated) but in the change you have to place a passage box
The corrugated pipe is forbidden in sight. Only allowed
