12. Piese de rezerva si accesorii

Toate operatiile de inlcocuire a anumitor suban-
!
sable sau accesorii ale intrerupatoarelor trebuie

echipamentelor si instalatiilor electrice. Inainte de
realizarea oricarei operatii trebuie verificat ca intre-
rupatorul este in pozitia deschis, arcul dezarmat si
se verifica lipsa tensiunii (medie tensiune si ten-
siunea de alimentare auxiliara).
