<p>Ute på bygda i Norge er det som oftest IT 230 V fordeling som gjelder.<br />IT kan enkelt oversettes fra fransk som IKKE JORDET, det gjelder trafokursen.<br />Det vil si at en jordfeil hos en strømbruker ikke uten videre vil brytes av jordfeilvern hvis det er i bruk.</p>
<p>Det som er spesielt er at en eller flere sikringskurser kan bli brutt i et hus som har jordfeilvern og utstyr tilkoblet utstyrt med avkoblingskondensator som f,eks PC og dimbare lyskurser.<br />Huset med jordfeil har muigens ikke jordfeilvern i sin kurs.</p>
<p>Sikringskursen i det øverste huset utløses da av kretsløpet:<br />L2 via nederste hus med jordfeil, strømbane videre via jord opp til hus med jordfeilvern og utstyr tilkoblet med jordet støpsel eller fast opplegg. Selv om utstyret er avslått med enkel polbryter så er den ene siden av avlederkondensatoren tilkoblet nettet.</p>
<p>Løsning: Gode naboer som oppgraderer sikringsskapet.</p>
