Ukuvuza komhlaba kuyinto yamanje efinyelela emhlabathini ngendlela engahlosiwe. Kunezigaba ezimbili: ukuvuza komhlaba okungahlosile okubangelwa ukufakwa noma ukwehluleka kwemishini nokuvuza ngenhloso okubangelwa indlela imishini eyenzelwe ngayo. "Idizayini" yokuvuza ingahle ibonakale iyinto exakile, kepha kwesinye isikhathi ayinakugwenywa - ngokwesibonelo, imishini ivame ukukhiqiza ukuvuvukala okuthile noma kusebenza kahle.
Kungakhathalekile ukuthi umthombo wokuvuza, kufanele uvikeleke ekubangeleni ukushaqeka kukagesi. Lokhu kuvame ukwenziwa ngokusebenzisa i-RCD (idivaysi yokuvikela ukuvuza) noma i-RCBO (Breaker yesekethe yokuvuza ngokuvikelwa ngokweqile). Balinganisa okwamanje ku-Rouctor Rouctor futhi bayiqhathanise namanje kumqhubi we-neutral. Uma umehluko udlula isilinganiso se-MA se-RCD noma i-RCBO, sizohamba.
Ezimweni eziningi, ukuvuza kuzosebenza njengoba bekulindelekile, kepha kwesinye isikhathi i-RCD noma i-RCBO izoqhubeka nokuhamba ngesizathu - lolu suku olucasulayo ". Indlela engcono kakhulu yokuxazulula le nkinga ukusebenzisa imitha yokuvuza yokuvuza, njengeMegger DCM305E. Lokhu kugobhozwa ngocingo kanye nomqhubi wesifundo ongathathi hlangothi (kodwa hhayi umqhubi wokuvikela!), Futhi kukala ukuvuza komhlaba kwamuva.
Ukuthola ukuthi yisiphi isifunda esidale uhambo lwamanga, cisha wonke ama-MCB kwiyunithi yokudla kwamandla bese ubeka ukuvuza komhlaba okuzungeza ikhebula lamandla. Vula umjikelezo ngamunye jikelele. Uma kubangela ukwanda okukhulu kokuvuza, lokhu kungenzeka kube umjikelezo onenkinga. Isinyathelo esilandelayo ukuthola ukuthi ukuvuza bekuyinhloso yini. Uma kunjalo, uhlobo oluthile lokusakazeka kwemithwalo noma ukuhlukaniswa kwesifunda kuyadingeka. Uma kungukuvuza okungahlosile - umphumela wokwehluleka - ukwehluleka kufanele kutholakale futhi kulungiswe.
Ungakhohlwa ukuthi inkinga ingaba yi-RCD noma i-RCBO enephutha. Ukubheka, ukwenza ukuhlolwa kwe-RCD ramp. Endabeni yedivaysi engu-30 MA - isilinganiso esivame kakhulu - kufanele sihambe phakathi kwama-24 no-28 Ma. Uma ihamba nge-waww yamanje, kungadinga ukushintshwa.
