Ulwazi olujwayelekile kanye nezidingo eziyisisekelo zokuvikela umbani 1. Hlola izinyathelo zokuvikela ukukhuphuka komhlabathi Hlola ukumelana nesisekelo sezinduku zombani, izakhiwo eziphakeme kanye nezinye izinsiza ukuze uqinisekise ukuthi umbani ungeniswa ngokushelela emhlabeni. Indlela yokuhlola eyisisekelo yokuvikela umbani: 1. Okokuqala thola umthofu ophansi noma ibhokisi loxhumano lwe-equipotential lenethiwekhi yokuvikela umbani. 2, ne-grounding ukumelana umhloli ukukala ukumelana emhlabathini (kukhona inqwaba test ezimbili 0.4M ukufaka inhlabathi, ibanga ukusuka iphuzu test 20 amamitha, a 40 amamitha, ngakho test iphuzu azungeze 42 amamitha ukuba umhlabathi) 3. Uma lincane inani le-grounding resistance value, lingcono. Inani elithile elifanelekayo kufanele licaciswe ngokuvumelana nezidingo zokuklama lapho umklamo unezidingo. 2. Hlola futhi ulondoloze izinto kanye nezinyathelo zokuphepha ngesikhathi sokusebenza kwensiza yokuvikela ukuhlinzwa Lapho idivayisi yokuvikela umbani isebenza, kuyadingeka ukuqinisa ukuhlola ukuze kutholwe futhi kusingathwe okudidayo kanye nokukhubazeka ngesikhathi ukuze kuvinjwe idivayisi yokuvikela umbani ekubeni ingabi namsebenzi noma ukusebenza kwedivayisi yokuvikela umbani kwehliswe. Izinto zokuhlola eziqondile zimi kanje: (1) Ingxenye ehola umbani yensimbi yokuvikela umbani, ulayini wokuhola ophansi kanye nomzimba ophansi kuxhumeke kahle. (2) Ukumelana nesisekelo kufanele kuhlolwe njalo ngesikhathi sokusebenza, futhi ukumelana nokunciphisa kufanele kuhlangabezane nezidingo ezicacisiwe. (3) Izinqamuleli zombani kufanele zenziwe njalo izivivinyo zokuvikela. (4) Induku yombani, i-conductor yombani kanye nocingo lwawo oluphansi kufanele kungabi namonakalo owenziwe yimishini kanye nokugqwala. (5) umkhono wokuvala umbani kufanele uphelele, indawo engaphezulu kufanele ingabi nemifantu, kungabikho ukungcola okungathi sína nokuxebuka kwe-insulation. (6) Bhala njalo izikhathi zokunyakaza zomuntu oboshiwe njengoba kuboniswe yirekhoda yokukhipha. (7) Ingxenye ephansi kufanele isekelwe kahle. Ngaphezu kwalokho, ngaphambi kwenkathi yonyaka yokuduma kwezulu, ukuhlolwa okuphelele, ukugcinwa, nokuhlolwa okudingekayo kokuvimbela ugesi kufanele kwenziwe.
