Throughout my professional career, I have assembled thousands of types of control panels, and I confess that many of them do not have a good financial return, precisely because they do not have an added value, because we know that the cost of labor is directly linked to the value of the material. On the other hand, we already have assemblies that have a very good added value, and with that we can have a very significant labor value, as is the case of this assembly that we will show in the video, because we will use a protection relay for a substation, and you will see that it is a highly valued assembly, but not many electricians can do it. #embaixadordecomandosengehall
