This poster emerged from the initiative of an electric company. The Termcat (Center of Terminology of the Generalitat of Catalonia), with the collaboration of this company, carried out the edition of the poster / brochure with the aim of disseminating terminology of electrical use in Catalan among consumers It was entrusted to the Small Commission to propose the termiology and the concept of this subject. Instead of making a current brochure with a list of terms, the idea of an illustrated poster was chosen, on the one hand, with terminology ranging from electrical production to internal consumption. On the other hand, tips for good use and to save.
