GFCI Kev Tiv Thaiv Tus Kheej Devices Test thiab Certification

Qhov tseem ceeb ntawm GFCI ntawv pov thawj
Peb cov kws tshaj lij pov thawj hauv kev tshawb fawb txog kev nyab xeeb thiab kev tsim vaj tsev ua rau peb ua haujlwm rau tag nrho cov kev lag luam tiv thaiv tus kheej, los ntawm kev cuam tshuam hauv av txhaum kev cuam tshuam (GFCI), portables thiab circuit breakers.Ib txheej txheem ntawv pov thawj tso cai rau koj kom tau txais txiaj ntsig los ntawm kev nrawm nrawm rau kev ua lag luam.Cov txheej txheem ua kom yooj yim thiab nrawm no txuag lub sijhawm thiab nyiaj txiag los ntawm kev ua pov thawj zoo thoob ntiaj teb cov ntawv pov thawj.Peb qhov kev pabcuam dav dav, hloov pauv tau qhov kev pabcuam suav nrog kev tshawb fawb thiab kev tsim kho, Kev Lag Luam Ntiaj Teb Kev Nkag Mus, kev teeb tsa thiab siv kawg.

Txheej txheem cej luam
GFCI yog ib qho khoom siv tiv thaiv tus kheej uas tiv thaiv tib neeg los ntawm kev ua txhaum hauv av: txoj kev tsis ncaj ncees ntawm hluav taws xob ntawm, piv txwv li, tus neeg siv lub tshuab fais fab thiab hauv av.Txoj kev rau qhov hluav taws xob tam sim no pib ntawm txoj hlua frayed ntawm lub tshuab fais fab, hla ib tus neeg, thiab xaus rau hauv av.

GFCI xeem cov cai thiab cov qauv
Lub ntsiab GFCIs them los ntawm UL 943 / CSA C22.2 No. 144.1 yog raws li nram no:

Receptacle GFCI
Portable GFCI
Circuit Breaker GFCI
Kuj tseem raug tshawb xyuas rau UL 489 Edition 13, Moulded-Case Circuit Breakers, Moulded-Case Switches, thiab Circuit Breaker Enclosures
UL 943 / CSA C22.2 No. 144.1 siv rau Chav Kawm A, ib leeg- thiab peb-theem, kev cuam tshuam hauv av cuam tshuam rau kev tiv thaiv cov neeg ua haujlwm, tsuas yog siv rau hauv av nruab nrab nruab nrab raws li National Electrical Code (NEC), ANSI/NFPA 70, Canadian Electrical Code, Part I, thiab Hluav Taws Xob (Siv), NOM-001-SEDE.

Cov GFCIs no yog tsim los siv rau alternating tam sim no (AC) circuits ntawm 120 V, 208Y / 120 V, 120/240 V, 127 V, los yog 220Y / 127 V, 60 Hz circuits.

Cov kev cai tshiab rau GFCIs tau raug pom zoo thiab yuav pib siv rau lub Tsib Hlis 5, 2021. Cov kev cai tshiab muaj feem xyuam nrog Kev Tshawb Fawb Txog Kev Tshawb Fawb Tshiab rau GFCIs, thiab cov tuam txhab tsim khoom ntawm GFCI tej zaum yuav xav tau kev sim ntxiv kom ua raws li cov cai tshiab.
