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?
