Uvavanyo lweZixhobo zoKhuseleko loBuqu lwe-GFCI kunye neSiqinisekiso

Ukubaluleka kwesiqinisekiso se-GFCI
Ubuchwephesha bethu obuqinisekisiweyo kwisayensi yokhuseleko kunye nobunjineli busenza ukuba sikwazi ukukhonza yonke imboni yokhuseleko lomntu, ukusuka kwi-receptacle ground fault circuit interrupter (GFCI), eziphathwayo kunye nezaphuli zesekethe.Inkqubo enye yokuqinisekiswa ikuvumela ukuba uzuze kwisantya esikhawulezayo ukuya kwintengiso.Le nkqubo ilungelelanisiweyo nekhawulezayo yonga ixesha nemali ngenkqubo yoqinisekiso lwehlabathi engqinwe kakuhle.Ipotifoliyo yethu yenkonzo ebanzi, eguquguqukayo ibandakanya uphando kunye nophuhliso, Ukufikelela kwiMarike yeHlabathi, ukufakwa kunye nokusetyenziswa kokuphela.

Isishwankathelo
I-GFCI sisixhobo sokukhusela umntu esikhusela abantu kwimpazamo yomhlaba: indlela yombane engafanelekanga phakathi, umzekelo, umsebenzisi we-drill drill kunye nomhlaba.Indlela yalo mbane iqala kwintambo eqhekekileyo ye-drill yamandla, idlule emntwini, iphele emhlabeni.

Iimfuno zovavanyo kunye nemigangatho ye-GFCI
Ezona GFCIs ezingundoqo ezigqunywe yi-UL 943/CSA C22.2 No. 144.1 zezi zilandelayo:

I-GFCI yokwamkela
GFCI ephathwayo
I-Circuit breaker GFCI
Kwakhona iphandwa kuHlelo lwe-13 lwe-UL 489, i-Molded-Case Circuit Breakers, i-Molded-Case Switches, kunye ne-Circuit-Breaker Enclosures.
I-UL 943 / CSA C22.2 No. 144.1 isebenza kwiKlasi A, isigaba esisodwa kunye nesigaba sesithathu, abaphazamisi beesekethe eziphantsi komhlaba ezijoliswe ekukhuseleni abasebenzi, ukusetyenziswa kuphela kwiinkqubo ezingathathi hlangothi ngokuhambelana neKhowudi yoMbane yeSizwe (NEC), I-ANSI/NFPA 70, iKhowudi yoMbane yaseKhanada, iCandelo I, kunye noFakelo loMbane (uSebenzisa), NOM-001-SEDE.

Ezi GFCIs zenzelwe ukusetyenziswa kwiisekethe zangoku (AC) ezitshintshanayo ze-120 V, 208Y/120 V, 120/240 V, 127 V, okanye 220Y/127 V, 60 Hz iisekethe.

Iimfuno ezitsha zee-GFCIs zamkelwe kwaye ziya kuqala ukusebenza nge-5 kaMeyi, 2021. Iimfuno ezintsha zinxulumene ne-Auto-Monitoring Function ye-GFCIs, kwaye abavelisi beemveliso ze-GFCI banokufuna uvavanyo olongezelelweyo ukuze bathobele iimfuno ezintsha.
