Re: naj npawb qhov hluav taws xob tom qab gfci ua
Siv 220.14, qhov siab tshaj plaws ntawm 13 receptacle qhov hluav taws xob tso cai rau ntawm 20A Circuit Court. Lawv ua tau ua ib leeg los yog dulpex thiab tseem tsuas suav ua ib qho chaw txais khoom.
Ib yam li ntawd, nws tau nug, puas yog GFCI qhov hluav taws xob tiv thaiv tag nrho cov hluav taws xob?
Yog, ib GFCI khoom , zoo li ib GFCI breaker, ua tiv thaiv tag nrho Circuit Court . Rau nruab a GFCI khoom rau tiv thaiv tag nrho khiav, koj yuav tsum nrhiav tus thawj txais tos qhov chaw ntawm lub Circuit Court . Txuas lub feed cables rau kab thiab lwm yam kom thauj khoom ntawm lub GFCI.
Tsis tas li ntawd, koj puas tuaj yeem daisy saw GFCI qhov chaw? Daisy chaining GFCI khoom siv ua tau ua teeb meem, txawm yog lawv zoo li yuav wired kom raug. Tus dej ntws GFCI ( txais tos ) tej zaum yuav ua ib qho kev ntsuam xyuas tus kheej thaum muaj zog, uas cov dej ntws GFCI (breaker) kuaj pom tias yog qhov txhaum. Koj tuaj yeem daisy - chain GFCIs yog koj xav tau tiag tiag. Lawv yuav tseem tiv thaiv zoo xwb.
Tom qab ntawd, ib tus tuaj yeem nug, yuav ua li cas thaum koj ntsaws GFCI qaum rau hauv GFCI qhov hluav taws xob?
Yog cov khoom siv ntsaws rau hauv ib qhov hluav taws xob tiv thaiv los ntawm a GFCI , lub hwj chim yuav raug kaw ua ntej muaj kev poob siab tuaj yeem tshwm sim. Cov circuits uas xav tau GFCI Kev tiv thaiv raug xaiv los ntawm National Electrical Code (NEC).
Koj puas tuaj yeem muaj 2 GFCI qhov hluav taws xob ntawm tib lub voj voog?
Koj nkaus xwb xav tau 1 GFCI qhov hluav taws xob rau Circuit Court (piv txwv tias nws yog qhov pib ntawm kab thiab lwm yam qhov hluav taws xob yog loads). Lawv yog raug wired nyob rau hauv parallel - yog lawv tau nyob rau hauv series, koj yuav tsis tau qhov tseeb voltage ntawm lwm tus qhov hluav taws xob thaum muaj tej yam load tam sim no. Nws yog ua tau.

Muaj ob lub ntsiab ntawm 220 qhov hluav taws xob, thiab lawv yuav tsum tau ceev faj ntxiv thiab cov cuab yeej tshwj xeeb rau kev xaim. Kev xaim 220 qhov hluav taws xob tuaj yeem ua rau muaj kev phom sij tshwj xeeb, yog li ntiav tus kws tshaj lij hluav taws xob, tshwj tsis yog tias koj muaj kev paub dhau los ntawm kev ua haujlwm hluav taws xob
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 tuaj yeem tiv thaiv kev tiv thaiv tsis zoo ua rau lub tshuab tawg?
Lub surge protector tuaj yeem muaj luv luv, tab sis siv lub zog hluav taws xob yuav tsum tsis txhob ua rau koj lub PC puas. Koj lub PC tsuas yog siv lub amperage nws xav tau, qhov hluav taws xob nce ntxiv tuaj yeem ua rau nws puas tsuaj tab sis kuv tsis paub txog tej lub hwj chim strips uas nce voltage. Nws kuj tseem tuaj yeem yog lwm yam ntawm Circuit Court overloading lub breaker
