Inqanaba lokukhusela lokutshintsha kwamashishini lihlala libizwa ngokuba yi-IP yokukhusela index. I-IP ibhekisela "kukhuseleko lokungena, ukukhuselwa kokufikelela", kwaye inqanaba lokukhusela libhalwe yi-IEC (International Electrotechnical Association). Ke, xa sithenga iiswitshi zamashishini, leliphi inqanaba le-IP elifanelekileyo lokutshintsha kwamashishini?

Hlela izixhobo zombane ngokweempawu zazo zokungangenwa luthuli kunye nokungangeni kwamanzi. Inqanaba lokhuseleko lwe-IP ngokubanzi liqulunqwe ngamanani amabini. Inombolo yokuqala imele isalathisi sokungena sothuli kunye nezinto zangaphandle (izixhobo, izandla, njl.), Inqanaba eliphezulu li-6; inombolo yesibini imele isalathisi sokutywinwa kwamanzi ezixhobo zombane, inqanaba eliphezulu Liyi-8. Inani elikhulu, liphezulu izinga lokukhusela.

Xa uthenga iutshintsho lwamashishini, abasebenzisi badla ngokukhetha ukutshintsha kweshishini kunye nenqanaba elifanelekileyo lokukhusela ngokwendawo yabo yokusetyenziswa. Ukutshintsha kwamashishini, inqanaba lokukhusela i-IP lisalathiso sothuli kunye nokuchasana kwamanzi, ngoko yintoni ebangela ukubahluko kwisalathisi? Oku ikakhulu kunxulumene neprofayile yeqokobhe lokutshintsha. Ukutshintsha kwamashishini ikakhulu kubandakanya iiprofayili zealluminiyam kunye neepleyiti zentsimbi. Ngokwahlukileyo, iialloyi ze-aluminium zinezinga eliphezulu lokukhusela.

Ukutshintshwa kwemizi-mveliso, inqanaba lokukhusela eliqhelekileyo elingaphezulu kwe-30 linokuziqhelanisa neendawo ezinzima zoshishino, kwaye inokuqinisekisa unxibelelwano olukhuselekileyo, oluthembekileyo, noluzinzileyo lokutshintsha kwezoshishino.
