Meter capacity inquiry

Hello, I am about to install a fourth air conditioner, I have 32A Thermal in main board with 6mm cable to the sectional board with 25A circuit breaker in sectional board, each air with its respective thermal, should I change some thermal or so how is banking?

With what you say ... that you have connected .... to know.

I have 3 refrigerators, two TVs, a dispenser, a washing machine. Obviously everything together is not connected, that's what you meant?

By 6 mm al, sectional.

Ah, maybe I express myself badly, I have the thermal of 32A behind the meter and from there goes the 6mm inside the house where I have the other board with the circuit breaker and so on !!

Like ... you say 4th air, pass the load in total to guide you.

The total load of all artifacts?

Yep ... we must know consumption of the 4 airs and what else you have connected, just as wiring exists for ex. In the air.

So far, with the information you give, all we can tell you is that the 25A circuit breaker is inappropriate since it does not have adequate protection
You must mention the power of all airs. We cannot speculate what may be usual for us

It may hold your installation, but you are at the limit.

Hello You do not give data of which air conditioners you have, (of what power), but I warn you that four (4) air conditioners plus normal consumption (and not so normal, three refrigerators) cannot be placed in a house fed with 6 mm², since you will have problems in summer, unless two of the four AAs are always standing. Remember that there are hot days where the AA and the refrigerators almost do not stop, above the power lines accuse for this reason, voltage drop. I comment on an assumption, since if you live in Tierra del Fuego, this will surely never happen. This is not theoretical, it has happened with clients in cases similar to the one you are commenting on. From 6 mm² I brought the feed to 10 mm², and the next year I made a three-phase rush. The problem is not the meter, it is the section of cable that will cause voltage drops in the house, increase in motor consumption and will end up firing the protections (or major damages if they were not well calculated).

In any case the maximum would be to use two airs at the same time? For the air I have thermal in each one and 2.5mm cable for daily devices I have 1.5mm and I have a light circuit and it takes apart!

Beyond the individual cable of the air (with 2.5 mm² each), the problem is the line from the network to the internal board where the AA circuits come out, It is the voltage drop and the consumption on the ppal board . You can try, if the thermal jumps you must change the line for one of more section, NEVER REPLACE THE THERMAL

The capacity of the meter can be read in its label I would recommend general thermal and differential circuit breaker of 40A and 10 mm² cables to the thermal distribution of terminal circuits inclusive With what you have you would be at the limit in moments of maximum load Regards

Ok great, minimally change that and inside I will try not to have everything at the same time ... thank you very much for the help! Regards

Faith I make a query, mostly I, I put a larger differential, so that it does not work as a thermal.

The differentials do not work as thermal (except as combined that are no longer sold). But if they require thermomagnetic protection of In less than or equal to that assigned to the differential
