Rezistenta la bornele unei prize

Recommended Posts

Guest Horatzyu

Salutare.Am o problema la instalatia electrica, se aude "clocotind" in tabloul electric si imi sare o siguranta, fara niciun consumator in prizele aferente acelei sigurante.Scotand firele din siguranta, am masurat circa 2,5 Kohmi la borne.Aceasta rezistenta mi se pare cam mica, ma gandeam ca trebuie sa tinda catre infinit => ca am un scurt intre fire...Ma inseala pe mine logica sau e normala aceasta valoare ?Va multumesc
