8 3} uf hlautxhawb nqa hnyav {{{{desutes cov khoom thiab kev sib sau loj dua
Ua tsaug rau nwsdurability, versatility, thiab yooj yim ntawm kev siv, UF {{{- b Khwv yog ib qho kev xaiv zoo tshaj plaws rau cov khoom hluav taws xob sab nraud.
4. Kev txiav txim siab rauUF - b hlau
Kev tsim kho kom raug ntawmUF - b hlauYuav tsum ua raws li NEC (National Electrical Code) cov qauv. Nws yuav tsumfaus tsawg kawg 18 ntiv tes tob, nyob ntawm cov hom av thiab thaj chaw, kom tsis txhob muaj kev puas tsuaj ntawm lub cev thiab ua kom muaj kev nyab xeeb. Hauv cov cheeb tsam uas cov hlau yuav raug rau kev cuam tshuam kev sib txawv, kev pom zoo txawm tias nws tsis tas yuav.
Xaiv txoj kev xaim xaim xaim xaim yog qhov tseem ceeb:
UF hlau 12 2Txhawb nqa txog 20 amps
