Autorizatia se elibereaza pe grade de competenta in functie de studii si de complexitatea lucrarilor care se vor executa. Este obligatoriu pentru personalul autorizat sa cunoasca toate actele normative legate de activitatea profesionala, normele de protectia muncii si de acordarea primului ajutor, normele de paza contra incendiilor,de utilizare a mijloacelor de alarma si de stingere a incediilor in instalatiile electrice.</div> <div style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px none; box-sizing: border-box; color: #3e454c; font-family: Roboto, sans-serif; font-size: 15px; line-height: 20px; margin-bottom: 5px; outline: 0px; padding: 15px 0px 0px; vertical-align: top;"> Tipul contorului care trebuie ales se face in functie de puterea totala de instalare, rezultand de aici un contor cu montaj direct sau indirect.</div> <div style="background-attachment: initial; background-clip: initial; background-image: initial; background-origin: initial; background-position: initial; background-repeat: initial; background-size: initial; border: 0px none; box-sizing: border-box; color: #3e454c; font-family: Roboto, sans-serif; font-size: 15px; line-height: 20px; margin-bottom: 5px; outline: 0px; padding: 15px 0px 0px; vertical-align: top;"> Tablourile de distributie in care sunt montate contoarele de inductie sunt parti componente ale instalatiilor electrice, care servesc concomitent la primirea si distributia energiei electrice si contin complete de aparate cu rol de conectare, protectie, masurare etc.</div> </div>
