Hello, I am going to do a home installation I want to put 32 sockets with 2.5 cable. 14 bulbs with 1.5 cable and its return with 1. 3 air intakes with 4 cable . The Pilar cable to the address of 6 They are 3 faces. It would be lighting, shots and airs What thermal and circuit breaker should I put? How to know if the measurements of the cables are correct for the energy consumption that the home will have and what calculation is made? The thermal is according to consumption or according to the cables? That would be right

Hello dear. For your problem I send you this table, individualize the lighting circuits, several sockets, and the air conditioning sockets. For 1.5mm cable a 10A thermomagnetic. For 2.5mm cable a thermomagnetic of 15 or 16A, this varies according to the brand, for thermomagnetic I recommend ABB or Siemens, or the most economical brand depends on where you live, SICA or BAW. For 4mm cable a 20A thermomagnetic. To know the consumption of each artifact you have to use Ohm's Law, in this case if you mark the Watts the artifacts, it is the Watts / Voltage gives us Amps, for example 4000W / 220 (I guess you are from Argentina) gives us a consumption of 18A, in that case you would have to have a thermomagnetic according to the cable, a cable always forgotten, and a thermomagnetic that trips before the maximum resistance of the cable. In this case you tell me it would be like this: An ID of 40A, to protect the TM of 10A and also the TM of 15A, that gives us 25A at maximum consumption, or an ID of 25A could also be optimal because it enters consumption and not It gets damaged. Then for the air conditioning sockets I recommend a TM of 20A, and an ID of 25A. You could divide those 32 sockets 16 sockets for a TM, it depends what you connect, not knowing I recommend the circuit separation of those 32 outlets. In short, we would have left. TM of 10A for lighting circuit, with a TM of 15A or 16A for the 16 sockets, another TM of 15A or 16A for the remaining 16 sockets, and a TM of 20A for air conditioners. Protect the lighting circuit of 10A, the two socket circuits of 15A or 16A, with an ID of 40A. Then protect the air circuit with an ID of 25A. I also recommend the installation of a grounding system, greetings and good luck. J.Ignacio Troya Electromechanical Technician
