Nws nta ib 250- ko taw ntev thiab yog tus yam ntxwv los ntawm nws 347-mil txheej kab uas hla, muab kev tiv thaiv zoo thiab kav ntev. Cov hlau yog tsim los nrog cov mos-annealed tooj liab conductors, kom ntseeg tau zoo heev hluav taws xob conductivity thiab yooj.
Cov cable no tau pom zoo raws li UL 83/719 cov qauv, lav nws ua raws li kev nyab xeeb thiab kev ua haujlwm zoo. Nws raug ntsuas rau 600 volts, ua rau nws haum rau ntau yam ntawm cov tshuab hluav taws xob. Lub 20-amp tam sim no ntsuam xyuas kom ntseeg tau tias nws tuaj yeem tswj tau cov khoom siv hluav taws xob ntau, thaum qhov ntsuas kub ntawm 90 degree tso cai rau nws ua haujlwm nyab xeeb hauv qhov chaw kub kub.
Qhov hnyav 107 phaus ib 1000 ko taw, cov hlau no yog tsim los ua kom ruaj khov thiab tswj tau. Cov khoom siv rwb thaiv tsev PVC muab kev tiv thaiv zoo tiv thaiv ya raws thiab kev puas tsuaj, txhim kho cov kab ntev thiab kev ntseeg tau. Nrog peb tus neeg xyuas pib, 12/3 NM-B xaim yog qhov zoo tagnrho rau kev siv ntau yam kev teeb tsa, suav nrog cov hom phiaj dav dav thiab cov ceg txuas txuas.

FAQ
Q: Muaj pes tsawg amps yuav 12/3 xaim nqa?
Q: Qhov txawv ntawm Romex UF-B thiab NM-B yog dab tsi?
NM-B (Non-Metallic Sheathed Cable):
Rwb thaiv tsev: NM-B cables feem ntau yog insulated nrog PVC (Polyvinyl Chloride) thiab muaj cov ntaub ntawv uas tsis yog xim hlau. Cov conductors nyob rau hauv NM-B cables feem ntau yog ua los ntawm mos-annealed tooj liab.
Daim ntawv thov: NM-B cables yog tsim rau siv sab hauv tsev thiab tsim nyog rau qhov chaw qhuav. Lawv feem ntau yog siv rau cov kab hluav taws xob hauv tsev, nrog rau cov teeb pom kev zoo, qhov hluav taws xob, thiab lwm yam khoom siv hluav taws xob.
UF-B (Underground Feeder Cable):
Rwb thaiv tsev: UF-B cables yog tsim los nrog ib tug tuab, ntau rugged PVC rwb thaiv tsev thiab muaj ib lub tsho sab nrauv. Qhov no ua rau lawv tiv taus ntau dua rau kev ya raws, kev puas tsuaj, thiab ib puag ncig kev puas tsuaj piv rau NM-B cables.
Daim ntawv thov: UF-B cables yog tsim los rau kev faus ncaj qha rau hauv av thiab siv rau kev teeb tsa sab nraum zoov qhov twg cov cable yuav raug ya raws lossis lwm yam kev mob ib puag ncig. Lawv tsim nyog rau cov ntawv thov xws li siv hluav taws xob sab nraum zoov, teeb pom kev zoo nkauj, thiab lwm yam sab nraum zoov.
Q: Puas yog NMB zoo ib yam li Romex?
A: Yog, lawv yog tib yam.
