Cov tais cableyog cov khoom tseem ceeb hauv kev teeb tsa hluav taws xob, muab txoj hauv kev rau cov xov hluav taws xob thiab cov xov hlau. Ntawm ntau hom cable trays, cov cable trays uas muaj npog yog qhov tseem ceeb rau kev tiv thaiv cov cables los ntawm cov yam ntxwv ib puag ncig thiab kev puas tsuaj rau lub cev. Kev nkag siab txog National Electrical Code (NEC) cov cai hais txog cable trays yog qhov tseem ceeb rau kev ua kom muaj kev nyab xeeb thiab kev ua raws li cov txheej txheem hluav taws xob.
Daim NEC, uas tau hloov kho txhua peb xyoos, qhia txog cov kev cai tshwj xeeb rau kev teeb tsa thiab siv cov tais cable hauv Tshooj 392. Tsab xov xwm no muab cov lus qhia txog kev tsim, kev teeb tsa, thiab kev saib xyuas cov tais cable, suav nrog cov tais cable uas muaj hau. Raws li NEC, cov tais cable yuav tsum tau ua los ntawm cov ntaub ntawv uas haum rau qhov chaw uas lawv tau teeb tsa. Qhov no suav nrog kev txiav txim siab rau kev tiv thaiv corrosion, kev ntsuas hluav taws, thiab lub peev xwm thauj khoom.
Ib qho ntawm cov ntsiab lus tseem ceeb ntawm NEC code raucov tais cableyog qhov yuav tsum tau ua kom muaj av thiab sib txuas zoo. Cov tais cable uas muaj hau yuav tsum tau muaj av kom tiv thaiv kev phom sij ntawm hluav taws xob, thiab NEC qhia meej txog cov hau kev kom ua tiav kev av zoo. Tsis tas li ntawd, cov cai hais kom cov tais cable uas muaj hau yuav tsum tau teeb tsa rau hauv txoj kev uas tso cai rau cua nkag thiab cua sov kom txaus, uas yog qhov tseem ceeb rau kev tswj hwm kev ncaj ncees ntawm cov cables uas nyob hauv.
Tsis tas li ntawd xwb, NEC hais txog qhov tseem ceeb ntawm kev tswj kom nkag mus rau cov tais cable kom meej rau kev tshuaj xyuas thiab kev saib xyuas. Qhov no yog qhov tseem ceeb rau cov tais cable uas muaj hau, vim tias lawv tuaj yeem ua rau pom tsis meej ntawm cov cables sab hauv. Kev sau npe thiab sau cov ntaub ntawv kom raug ntawm cov cables hauv lub tais kuj tseem yuav tsum tau ua kom yooj yim rau kev saib xyuas thiab daws teeb meem yav tom ntej.
Hauv kev xaus, NEC code rau cable trays, suav nrogcov tais cable uas muaj cov ntaub thaiv npog, yog tsim los kom muaj kev nyab xeeb, kev ntseeg siab, thiab kev ua haujlwm zoo hauv kev teeb tsa hluav taws xob. Kev ua raws li cov cai no tsis yog tsuas yog tiv thaiv kev ncaj ncees ntawm lub tshuab hluav taws xob xwb tab sis kuj txhim kho kev nyab xeeb ntawm ib puag ncig uas nws ua haujlwm.
