GFCI Receptacle vs. Circuit Breaker

National Electric Code (NEC) ndi ma code onse omangira am'deralo amafunikira chitetezo chosokoneza dera pazida zambiri zamkati ndi kunja.Zofunikira zilipo kuti ziteteze ogwiritsa ntchito kugwedezeka pakakhala vuto la pansi, momwe magetsi amayendera mwangozi kunja kwa dera lokhazikitsidwa.

Chitetezo chofunikirachi chikhoza kuperekedwa ndi chophwanya dera kapena zotengera za GFCI.Ubwino ndi kuipa kwa njira iliyonse zimadalira kuyika.Komanso, chonde dziwani kuti khodi yamagetsi yapafupi - malamulo omwe muyenera kutsatira kuti muyendetse magetsi - angakhale ndi zofunikira zenizeni za momwe mungatetezere GFCI m'dera lanu.

Kwenikweni, onse ophwanya dera ndi chotengera cha GFCI akuchita zomwezo, kotero kusankha koyenera kumafuna kuti muyese zabwino ndi zoyipa za chilichonse.

Kodi GFCI Receptacle ndi chiyani?

Mutha kuweruza ngati chotengera ndi GFCI kapena ayi ndi mawonekedwe ake akunja.GFCI imaphatikizidwa mumagetsi ndipo idapangidwa ndi batani lokhazikitsiranso lofiyira (kapena loyera) pagawo lakumaso.Chotulukacho chimayang'anira kuchuluka kwa mphamvu zomwe zimalowamo zikagwiritsidwa ntchito.Ngati kuchulukitsitsa kwamtundu uliwonse wamagetsi kapena kusalinganizika kwazindikirika ndi chotengeracho, chimapangidwa kuti chiziyenda mozungulira kachigawo kakang'ono ka sekondi imodzi.

Zotengera za GFCI nthawi zambiri zimagwiritsidwa ntchito m'malo mwa chotengera chokhazikika kuti chiteteze malo amodzi.Komabe, zotengera za GFCI zitha kulumikizidwa m'njira ziwiri zosiyana motero zimapereka magawo awiri achitetezo.Chitetezo cha mawaya pamalo amodzi chimapereka chitetezo cha GFCI pachotengera chimodzi chokha.Mawaya okhala ndi malo angapo amateteza chotengera choyamba cha GFCI ndi chotengera chilichonse chakumunsi kwake mudera lomwelo.Komabe, siziteteza gawo la dera lomwe lili pakati pawokha ndi gulu lalikulu lautumiki.Mwachitsanzo, ngati chotengera cha GFCI chokhala ndi mawaya oteteza malo angapo chili cholandirira chachinayi pagawo lomwe lili ndi malo asanu ndi awiri, apa malo atatu oyamba sadzatetezedwa.

Kukhazikitsanso chotengera ndikosavuta kuposa kupita kugawo lautumiki kuti mukhazikitsenso chowotcha, koma dziwani kuti ngati mutumiza waya kuti muteteze malo angapo kuchokera pachotengera chimodzi cha GFCI, chotengeracho chimawongolera chilichonse kunsi kwa mtsinje.Muyenera kubwerera m'mbuyo kuti mupeze cholandirira cha GFCI kuti muyikhazikitsenso ngati pali vuto lililonse la waya kumunsi.

Kodi GFCI Circuit Breaker ndi chiyani?

GFCI circuit breakers amateteza dera lonse.GFCI circuit breaker ndi yosavuta: poyika imodzi mu gulu lautumiki (bokosi losweka), imawonjezera chitetezo cha GFCI kudera lonse, kuphatikizapo mawaya ndi zipangizo zonse ndi zipangizo zogwirizanitsidwa ndi dera.Nthawi zina chitetezo cha AFCI (arc-fault circuit interrupter) chimayitanidwanso (chinthu chofala kwambiri), pamakhala ntchito ziwiri GFCI/AFCI zophwanya ma circuit zomwe zingagwiritsidwe ntchito.

GFCI ophwanya ma circuit amamveka ngati malo onse ozungulira amafunikira chitetezo.Mwachitsanzo, tiyerekeze kuti mukuwonjezera dera lolandirira malo ochitiramo garage kapena malo akulu akunja a patio.Chifukwa zotengera zonsezi zimafuna chitetezo cha GFCI, mwina ndizothandiza kwambiri kuyimitsa ma waya ndi GFCI breaker kuti chilichonse chozungulira chitetezedwe.Ophwanya GFCI amatha kunyamula mtengo wokwera, komabe, kuchita izi sikukhala kosankha ndalama zambiri.Mwinanso, mutha kuyika chotulutsa cha GFCI poyambira koyamba pagawo kuti mupereke chitetezo chomwecho pamtengo wotsika.

Nthawi Yomwe Mungasankhire Chotengera cha GFCI Pa GFCI Circuit Breaker

Muyenera kupita ku gulu lautumiki kuti muyikhazikitsenso pamene wophwanya GFCI ayenda.Chotengera cha GFCI chikayenda, muyenera kuyikhazikitsanso pamalo olandirira.National Electrical Code (NEC) imafuna kuti zotengera za GFCI zikhale m'malo opezeka mosavuta, kuwonetsetsa kuti pali njira yosavuta yokhazikitsira chotengeracho ngati chikuyenda.Chifukwa chake, zotengera za GFCI siziloledwa kumbuyo kwa mipando kapena zida.Ngati mudzakhala ndi zotengera zomwe zimafunikira chitetezo cha GFCI m'malo awa, gwiritsani ntchito chophwanya GFCI.

Nthawi zambiri, zotengera za GFCI ndizosavuta kukhazikitsa.Nthawi zina chigamulo chimabwera pafunso lakuchita bwino.Mwachitsanzo, ngati mukufuna chitetezo cha GFCI pa chotengera chimodzi kapena ziwiri - kunena, bafa kapena chipinda chochapira-mwina zimakhala zomveka kuyika zotengera za GFCI pamalo awa.Komanso, ngati ndinu DIYer ndipo simukudziwa kugwira ntchito pagulu lautumiki, kusintha cholandirira ndi njira yosavuta komanso yotetezeka kuposa kulowetsa wowononga dera.

Zotengera za GFCI zimakhala ndi matupi akuluakulu kuposa zotengera wamba, kotero nthawi zina malo okhala mkati mwa bokosi la khoma amatha kukhudza kusankha kwanu.Ndi mabokosi amtundu wokhazikika, sipangakhale malo okwanira owonjezera chotengera cha GFCI mosamala, pamenepa kupanga chophwanya dera la GFCI kungakhale chisankho chabwinoko.

Mtengo ukhozanso kukhala chinthu chofunikira pa chisankho.Chotengera cha GFCI nthawi zambiri chimawononga $15.Wosweka wa GFCI angakuwonongereni $40 kapena $50, motsutsana ndi $4 mpaka $6 pa chophwanya wamba.Ngati ndalama ndizovuta ndipo mumangofunika kuteteza malo amodzi, malo ogulitsira a GFCI atha kukhala chisankho chabwino kuposa chophwanya GFCI.

Pomaliza, pali nambala yamagetsi yakumaloko, yomwe ingakhale ndi zofunikira za GFCI zosiyana ndi zomwe NEC inanena.
