Ukubaluleka kwesitifiketi se-GFCI
Ubungcweti bethu obufakazelwe besayensi yezokuphepha nobunjiniyela busenza sikwazi ukuhlinzeka yonke imboni yokuvikela umuntu, kusukela kusiphazamisi se-ground fault circuit (GFCI), izinto eziphathwayo kanye nama-circuit breaker.Inqubo eyodwa yesitifiketi ikuvumela ukuthi uzuze ngesivinini esisheshayo uye emakethe.Le nqubo eyenziwe lula futhi esheshiswayo yonga isikhathi nemali ngohlelo olufakazelwe kahle lwesitifiketi somhlaba wonke.Iphothifoliyo yethu yesevisi ebanzi, eguquguqukayo ihlanganisa ucwaningo nentuthuko, Ukufinyelela Kwemakethe Yomhlaba Wonke, ukufakwa kanye nokusetshenziswa kokugcina.
Uhlolojikelele
I-GFCI iyisisetshenziswa sokuzivikela esivikela abantu ekulimaleni komhlabathi: umzila kagesi ongahlosiwe phakathi, ngokwesibonelo, umsebenzisi we-drill yamandla nomhlabathi.Indlela yalo msinga kagesi iqala entanjeni ephukile yokubhoboza amandla, idlule kumuntu, futhi iphelele phansi.
Izidingo zokuhlolwa kwe-GFCI namazinga
Ama-GFCI amakhulu embozwe yi-UL 943/CSA C22.2 No. 144.1 ami kanje:
I-GFCI yokwamukela
I-GFCI ephathekayo
I-Circuit breaker GFCI
Kuphenywa futhi ku-UL 489 Edition 13, ama-Molded-Case Circuit Breakers, ama-Molded-Case Switches, kanye ne-Circuit-Breaker Enclosures.
I-UL 943/CSA C22.2 No. 144.1 isebenza ku-Class A, iziphazamisi zesekethe yamaphutha aphansi ezihloselwe ukuvikela abasebenzi, ukuze zisetshenziswe kuphela ezinhlelweni ezingathathi hlangothi ezisekelwe phansi ngokuhambisana ne-National Electrical Code (NEC), I-ANSI/NFPA 70, Ikhodi Yogesi yaseCanada, Ingxenye I, Nokufakwa kukagesi (Ukusetshenziswa), NOM-001-SEDE.
Lawa ma-GFCI enzelwe ukusetshenziswa kumasekhethi amanje (AC) ashintshanayo angu-120 V, 208Y/120 V, 120/240 V, 127 V, noma 220Y/127 V, 60 Hz amasekhethi.
Izidingo ezintsha zama-GFCI zigunyaziwe futhi zizoqala ukusebenza ngomhla ka-5 Meyi, 2021. Izidingo ezintsha zihlobene Nomsebenzi Wokugada Okuzenzakalelayo wama-GFCIs, futhi abakhiqizi bemikhiqizo ye-GFCI bangadinga ukuhlolwa okwengeziwe ukuze bathobelane nezimfuneko ezintsha.
