GFCI Personal Protection Devices Testing and Certification

Kufunika kwa certification ya GFCI
Ukadaulo wathu wotsimikizika pazachitetezo cha sayansi ndi uinjiniya umatithandiza kuti tizitha kugwiritsa ntchito makampani onse odzitetezera, kuchokera ku cholumikizira chapansi pamagetsi (GFCI), ma portable ndi ma circuit breaker.Njira imodzi yotsimikizira imakupatsani mwayi wopindula ndi liwiro lothamanga kupita kumsika.Njira yowongoka komanso yofulumira iyi imapulumutsa nthawi ndi ndalama kudzera mu pulogalamu yotsimikiziridwa bwino yapadziko lonse lapansi.Ntchito yathu yayikulu, yosinthika yantchito imakhudza kafukufuku ndi chitukuko, Global Market Access, kukhazikitsa ndi kugwiritsa ntchito kumapeto.

Mwachidule
GFCI ndi chipangizo chodzitetezera chomwe chimateteza anthu ku zolakwika zapansi: njira yamagetsi yosakonzekera pakati, mwachitsanzo, wogwiritsa ntchito kubowola mphamvu ndi pansi.Njira yamagetsi imeneyi imayambira pa chingwe chophwanyika cha pobowola mphamvu, imadutsa mwa munthu, n’kukathera pansi.

Zofunikira pakuyesa kwa GFCI ndi miyezo
Ma GFCI akuluakulu opangidwa ndi UL 943/CSA C22.2 No. 144.1 ndi motere:

Chotengera GFCI
GFCI yonyamula
Circuit breaker GFCI
Amafufuzidwanso ku UL 489 Edition 13, Molded-Case Circuit Breakers, Molded-Case Switches, ndi Circuit-Breaker Enclosures.
UL 943/CSA C22.2 No. 144.1 imagwiranso ntchito ku Gulu A, limodzi ndi magawo atatu, osokoneza magetsi apansi omwe amatetezedwa kuti ateteze anthu ogwira ntchito, kuti agwiritsidwe ntchito pokhapokha pamakina osalowerera ndale malinga ndi National Electrical Code (NEC), ANSI/NFPA 70, Canadian Electrical Code, Part I, and Electrical Installations (Ntchito), NOM-001-SEDE.

Ma GFCIwa amapangidwa kuti azigwiritsidwa ntchito pa ma circuit alternating current (AC) a 120 V, 208Y/120 V, 120/240 V, 127 V, kapena 220Y/127 V, 60 Hz.

Zofunikira zatsopano za ma GFCI zavomerezedwa ndipo ziyamba kugwira ntchito pa Meyi 5, 2021. Zofunikira zatsopano zikugwirizana ndi Auto-Monitoring Function for GFCIs, ndipo opanga zinthu za GFCI angafunike kuyesa kowonjezereka kuti agwirizane ndi zofunikira zatsopano.
