Ukuvuza komhlaba kukwindawo yangoku efikelela emhlabeni ngendlela engaphelelwanga. Kukho iindidi ezimbini: ukuvuza okungagungqi okungengulo kubangelwa kukuntywila okanye ukungaphumeleli izixhobo kunye nokuvuza komhlaba ngabom obangelwe yindlela eyenziwe ngayo izixhobo. "Uyilo" lokuvuza lungabonakala lungaqhelekanga, kodwa ngamanye amaxesha alunakufikeleleka - umzekelo, izixhobo ze-IT zihlala zivelisa ukuvuza nokuba kuyasebenza ngokufanelekileyo.
Nokuba nguMthombo wokuvuza, kufuneka uthintelwe ekubeni ungothuswe ngombane. Oku kuhlala kwenziwe ngokusebenzisa i-RCD (isixhobo sokukhusela i-leakic) okanye i-RCBO (ukuvuza i-leakbocker offerent). Balinganisa okwangoku umqhubi womgca kwaye bathelekisa neQela eliKhohliweyo. Ukuba umahluko ungaphezulu kwe-ratime ye-RCD okanye i-RCBO, iya kuhamba.
Kwiimeko ezininzi, ukuvuza kuya kusebenza njengoko kulindelwe, kodwa ngamanye amaxesha i-RCD okanye i-RCD iya kuqhubeka nokuhamba ngaphandle kwesizathu-oku "kuhambo olucaphukisayo". Eyona ndlela ilungileyo yokusombulula le ngxaki kukusebenzisa imitha yokuvuza i-threp, njenge megger dcm305e. Oku kuqhutywa kwi-wire kunye nomqhubi ongathathi hlangothi (kodwa hayi umqhubi okhuselayo!), Kwaye ilinganisa umhlaba oza kuvuza.
Ukufumanisa ukuba yeyiphi inqanawa yesiphaluka ebangele uhambo lobuxoki, cima zonke i-MCBs kwicandelo elithabatha amandla kwaye ubeke indawo yokuvuza umhlaba ikhwele intambo yamandla. Vula isekethe nganye. Ukuba ibangela ukwanda okukhulu kokuvuza, kunokwenzeka ukuba kube yisekethe ingxaki. Inyathelo elilandelayo kukufumanisa ukuba ivulekile ngabom. Ukuba kunjalo, ezinye iindlela zokusasazeka komthwalo okanye ukwahlula isiphaluka ziyafuneka. Ukuba yindawo yokuvuza engacwangciswanga-isiphumo sokungaphumeleli - ukusilela ukufunyanwa kwaye kulungiswe.
Ungalibali ukuba ingxaki inokuba yi-RCD engalunganga okanye i-RCBO. Ukujonga, ukwenza uvavanyo lwe-rcd ramp. Kwimeko yesixhobo esingama-30 esinexabiso eliqhelekileyo-kufuneka uhambo phakathi kwe-24 ne-28 ma. Ukuba ihamba ngokusezantsi, kunokufuneka itshintshwe.
