Hom NM-B 14/3 nrog av yog ib hom non-metallic sheathed cable, feem ntau hu ua "Romex," siv nyob rau hauv vaj tse thaiv. Ua raws li UL83 rau thermoplastic insulated hlau thiab cable qauv, thiab UL719 rau cov hlau tsis yog hlau sheathed cables, suav nrog NM hlau thiab NMC hlau.
Daim ntawv thov
Hom NM-B (Non-metallic sheathed cable) muaj ntau yam kev siv raws li tau hais tseg hauv Tshooj 334 ntawm National Electrical Code (NEC). Hom NM-B cable feem ntau yog siv rau kev xaim hluav taws xob hauv tsev ntawm luminaries, khoom siv, thiab khoom siv. Hom NM-B ampacity txwv yuav tsum ua raws li 60ºC tus neeg xyuas pib ntsuas kub, raws li tau teev tseg hauv NEC. Hom NM-B yog ntsuas 600V rau ob qho tib si nthuav tawm thiab zais ua haujlwm hauv ib txwm qhuav qhov chaw. Hom NM-B tej zaum yuav raug ntsia los yog nuv ntses hauv huab cua voids thiab cov pob qij txha thiab hauv cov masonry thaiv los yog cov pobzeb phab ntsa uas cov phab ntsa no tsis raug, los yog raug rau, dej noo ntau dhau los yog dampness.
Feature
1.Conductors: khoom 14 AWG uncoated tooj liab conductors, muab zoo heev conductivity thiab kev cia siab rau cov hluav taws xob hauv tsev.
2. Rwb thaiv tsev: Cov conductors yog insulated nrog ib tug xim-coded Polyvinyl Chloride (PVC) compound, uas ua tau raws li qhov yuav tsum tau thickness rau hom THHN los yog THWN -2 rwb thaiv tsev qauv.
3. Grounding Conductor: Lub cable muaj xws li ib tug mos, uncoated tooj liab grounding conductor.
4. Jacket: Tag nrho cov sib dhos yog encased nyob rau hauv ib tug nplaim-retardant thiab ya raws-resistant PVC tsho.
Daim ntawv pov thawj
NM-B cable yog UL tau ntawv pov thawj, uas txhais tau hais tias cov khoom tau raug tshuaj xyuas nruj me ntsis thiab pom zoo los ntawm UL hais txog kev tsim, xaiv cov khoom siv, kev tsim khoom thiab kev ua haujlwm kawg. Cov hlau tuaj yeem muab cov khoom siv hluav taws xob txhim khu kev qha thiab kev nyab xeeb hauv ntau qhov chaw thov.
