A chav 1 circuit yog ib feem ntawm lub kab hluav taws xob system nruab nrab ntawm lub load sab ntawm lub overcurrent tiv thaiv ntaus ntawv (OCPD) los yog lub zog -limited mov thiab kev cob cog rua load. Piv txwv li, Class 1 zog - txwv circuits yog muab los ntawm a zog muab nrog cov zis uas tsis pub tshaj 30 volts thiab 1,000 volt-amps.
Tsis tas li ntawd, qhov sib txawv ntawm Chav Kawm 1 thiab Chav Kawm 2 yog dab tsi?
Class 1 kab yog qhov yuav tsum tau ua kom dhau cov qauv rau lub zog thiab teeb pom kev zoo kab hluav taws xob . Nws yuav tsum zaum hauv cov hlau los yog cov hlau tsis yog hlau los yog hlau-sheathed kab hluav taws xob piv rau jacketed kab xws li hom NM. Chav kawm 3 kab hluav taws xob yog functionally zoo ib yam li Class 2 kab , tab sis nrog ntau dua voltage thiab hwj chim txwv.
Ib yam li ntawd, qhov siab tshaj plaws tso cai voltage ntawm chav kawm 1 Circuit Court yog dab tsi? 30 volts
Kuj tseem paub yog, dab tsi yog Class 2 hluav taws xob circuit?
NEC txhais a Chav Kawm 2 circuit raws li qhov feem ntawm cov xaim hluav taws xob nruab nrab ntawm sab load ntawm a Chav kawm 2 lub zog qhov chaw thiab cov khoom siv txuas nrog. Vim nws txwv lub zog, a Chav Kawm 2 circuit suav hais tias muaj kev nyab xeeb los ntawm qhov pib qhov hluav taws kub thiab muab kev tiv thaiv zoo los ntawm hluav taws xob poob siab.
Class 2 thiab 3 circuits yog dab tsi?
Class 2 thiab 3 circuits txhais tau tias yog ib feem ntawm cov kab hluav taws xob nruab nrab ntawm cov khoom siv hluav taws xob thiab cov khoom siv txuas nrog. Class 3 circuits txwv lub zog tso zis mus rau theem uas feem ntau yuav tsis pib hluav taws. Txawm li cas los xij, lawv tuaj yeem ua tau thiab ua haujlwm ntawm qib siab dua thiab, yog li, tuaj yeem ua rau muaj kev phom sij txaus ntshai.

Yuav ua li cas koj xaim hluav taws xob tiv thaiv hluav taws xob?
Ntxig txhua lub xaim rau hauv lub qhov tsim nyog hauv qhov chaw txais khoom tshiab thiab ceev cov ntsia hlau davhlau ya nyob twg kom ruaj ntseg. Qhwv qhov kawg ntawm cov tooj liab liab lossis ntsuab xaim (hauv av) nyob ib ncig ntawm cov ntsia hlau ntsuab thiab nruj. Maj mam thawb lub qhov hluav taws xob rov qab rau hauv lub thawv thiab ceev cov ntsia hlau mounting
Dab tsi ua rau lub qhov hluav taws xob muaj hluav taws xob tsawg?
Ib qho laj thawj uas lub qhov hluav taws xob yuav muaj lowvoltageis uas nws hnav tawm. Cov hluav taws xob hluav taws xob tuaj yeem hnav tawm tib yam li txhua yam khoom siv lossis cov khoom siv hluav taws xob.Qhov txuas tsis tu ncua thiab tshem tawm cov hlua rau hauv lub qhov hluav taws xob tuaj yeem loosen thiab hnav cov kev sib txuas
Chav hluav taws xob hloov hluav taws xob yog dab tsi?
Chav hloov. ib cheeb tsam uas muaj kev sib dhos ntawm cov khoom siv hluav taws xob rau kev tswj thiab kev tiv thaiv hluav taws xob circuits. chav hloov pauv tuaj yeem cuam tshuam rau lub substation tab sis tsuas muaj cov keyboards xwb. lub ntsiab hloov mus rau cais tawm hluav taws xob yog nyob rau hauv lub ntsiab switchroom
Puas tuaj yeem tiv thaiv hluav taws xob tiv thaiv hluav taws xob?
Surge protectors tiag tiag yuav tiv thaiv cov khoos phis tawj thiab lwm yam khoom siv hluav taws xob los ntawm lub zog hluav taws xob thiab feem ntau cov xob laim nyob deb, tab sis lawv tsis tuaj yeem tiv thaiv lub teeb pom kev ncaj qha los ntawm kev puas tsuaj rau cov khoom siv sib txuas
Puas yog txhua lub tshuab hluav taws xob muaj GFCI qhov hluav taws xob?
Duplex (ob chav) qhov hluav taws xob muaj nyob rau ntawm lub tshuab hluav taws xob nqa tau thiab txhua qhov khoom siv 120 volts. Hauv av txhaum kev tiv thaiv qhov hluav taws xob (GFCI) yog qhov tshwj xeeb ntawm qee cov qauv thiab tiv thaiv tus neeg siv los ntawm hluav taws xob shocks
