doubt with the pillar

Good morning, I'm from Argentina I have a consultation, here for an enrolled person to approve the pillar I need to put a 2x40a + 2x32a circuit breaker in the back box of the pillar, what I thought I would do is! put the 2x40a diyuntor and put a 4x32 and remove phase and neutral for common use and the other two poles remove face and neutral to use it for shots of 20a as would future airs and a welder, you recommend me do that? or put 2 individual bipolar thermals, or do that on a sectional board inside the house?

The connection is not correct as they told you, but it seems to me that what you are trying to say without having written it ... is that you are afraid that you will be short of the 32A
If so, comment. Since you mentioned a welder plus AA and the typical consumption of the house, it would rather come to extend the supply

Hello It is not right what you want to do; in the abutment you must place the main board according to strict regulations, you can not choose any amount, configuration or amperage, otherwise you will not be approved. Regarding the choice of maneuver and safety elements, everything depends on the selected connection cable, which depends on the power to be installed, based on this cable you have to place the corresponding protection; as an example, if it is a 6 mm single-phase lowering, you can put a protection of 2 x 32A (maximum) and a differential circuit breaker (30mA) 40A, in that order, this will allow you to consume approximately 5 or 6 Kva. If it is 4 mm, you can use 25A double thermal and 25A (30mA) current cutter. For distribution, there is no problem that you do it in the same cabinet, in the pillar; but as colleagues say (greetings), that should be done inside the house for reasons of comfort (and security); you can not have elements of protection and maneuver to the intemperie, that is of common sense. The different circuits are always sectioned with dual thermomagnetic in single-phase installations. After placing the general protection, you can assemble as you want, always according to consumption, your sectional board and place double thermal for the lines you plan to do. If the distance from the pillar to the house is less than three meters (this depends on local regulations), you can place the thermal cut and the differential circuit breaker on a board inside the house; if this is more than three meters, but less than ten (depending on local regulations), you can also place the differential circuit breaker inside this, always leaving the main cutting thermal at the side of the pillar. This exception you must find out in the electric service provider of your city. You have doubts, consult. regards

Hello the general thermomagnetic is compulsory and must cover 100% of the loads present. You can not put circuits that do not pass through thermomagnetic. I, as a registered professional, would not sign the certificate on the other hand a four-phase thermal is not equivalent to two bipolar thermals ... do not confuse things, it is not the same ... what if you can have is several sectional circuits or terminals in the main board but respecting an order 1) general thermomagnetic 2) differential switch 3) sectional thermonuclear or terminal 1 4) sectional thermomagnetic or terminal 2 ...... 5) thermomagnetic sectional or terminal n .... (as many thermonnetics as circuits leave the board) regards

The separation of the circuits is done in the secondary board, inside the house. a greeting George

that is done inside the house there you have to make the circuits that you want with their respective differential protections cable to ground and the cable suitable for each circuit with its thermal protection

Good morning, I understand what they say to me and thank you for explaining it to my understanding, so I understood first the TM then the Diferncial, but in my home I have it backwards, the direct line goes down to a 40a circuit breaker and there I pass it to the thermics of 32a and it reaches the sectional board of inside that I have a thermics more than 20 a (that the use for general cut of inside) and two circuits one with thermal of 10a (Cable 1.5 mm and returns of 1mm ) and thermos of 16a (line of shots of 10a) ... well done that?

It is not quite right but it goes ....
The general TM goes first but it is a subject quite discussed between the electricians, there are those who agree and those who do not ... the returns of 1mm² at least until today are anti-regulation. There is a new regulation not yet in force where it will be allowed to use 1 mm² but until it enters into force the minimum is 1.50 mm²
The rest is fine as long as the shots are 2.50 mm² and both circuits do not exceed 15 mouths per circuit

Another important point that was not discussed is the grounding
In lighting circuit and minimum sockets 2.50 mm²
In the lower minimum 6 mm² assuming that the circuit that feeds the house is 6 mm² since 4 mm² would not be correct for the TMG of 32
Grounding is important and if it does not exist you must incorporate it
