Contracted power vs consumption.

Hello everyone! My question is: Suppose I have contracted a power of 15kw and the provider provides me with a transformer with that power. After that transformer I am connected to a pillar in my land, a pillar from which I make all my electrical energy consumption. What would happen if I had a consumption of 20 kW? 1-skip the thermals 2-jump circuit breakers 3-burner transformer fuse 4-others

Hello It all depends on the overload range you have available. If your declared consumption is 15 kW you can not put a 15 kW transformer because you have no margin The first one that should jump due to overload is the closest thermal or fuse and upstream of said overload Circuit breakers (differential) do not act due to overload If you have a consumption of 15 kW you must have cables that support it and protections that protect the cables but at the same time do not react to normal maximum loads in short, maybe the transformer turns out to be like double What if ... many companies place a power limiter so you should be careful what is declared Regards

Hello, if everything is at the limit of its caacity, you cannot have simultaneous loads above that capacity. If you have a 15kw transformer. You can't ask for 20kw. and of course the company will not give you a 15kw contract. with 15kw transformer. and air fuse of more than 15 kw. Therefore, the ipotetic of your query is not normal, because it is outside the proposed parameters. The transformers also overheat and if they are required beyond their capacity, they can explode, and in addition the fuses are set to limit the loads to a maximum consumption and not above that consumption, the thermomagnetic protection act in the same way , with a little delay, but these in that case, do not affect the excess in the demand for current, the rush, greetings alualo.

Thank you very much for your answers both are very useful and understandable! I specify the case a little more to make it clearer. If I have contracted 15kw of power with 10kw consumption and after one year my consumption grows. What happens at the moment you exceeded the limit or reached it !? Thank you!

From the administrative aspect, if it is detected by the company, it may apply fines
From the technical aspect you can suffer the consequences of an overloaded installation unless the installation is qualified for this increase in power. What is internal can prevent and reinforce it but what is external (of the company) does not ...
