When we say electrical installation inspecting and testing, in Croatia, by law prior to usage permit every new construction/building/etc that has electrical installation needs to be tested as follow: 

  • Measurement and testing of fault loop current (Mjerenje i ispitivanje struje petlje kvara)
  • Measurement and testing of grounding resistance (Mjerenje i ispitivanje otpora uzemljenja)
  • Cable insulation resistance test (Ispitivanje otpora izolacije kabela)
  • Examination of lightning protection installation (Ispitivanje gromobranske instalacije)
  • Testing of the differential current protective device (DCU) (Ispitivanje zaštitnog uredaja diferencijalne struje (ZUDS))
  • Functional testing of the electrical installation (Funkcionalno ispitivanje elektroinstalacije)
  • Testing the continuity of the protective conductor
  • Examination of potential equalization measures
  • Testing of bimetallic protections and motor protection switches
  • Testing the emergency shutdown button
  • Panic lighting test
