Malo osokoneza bongo amadziwika bwino amatchedwa break- breaker breaker, kapena kungokhala GFCI . Amayika pakhomo la utumiki wa kunyumba, kapena bokosi losweka, ndipo amapereka chitetezo cha GFCI ku ofesi yonse ya nthambi yomwe ikugwira ntchito. Kukonzekera uku kumagwiritsidwa ntchito mobwerezabwereza pofuna kukhazikitsa zotengera za GFCI (malo ogulitsa) kumalo ena kumene kuli kofunika ndi code ya magetsi.
Mphungu wa GFCI umayika ngati ofanana ndi ozungulira dera limodzi, koma pali kusiyana kwakukulu koyenera kumudziwa. Ndiponso, chotsala cha GFCI chatsopano chiyenera kukhala mtundu woyenera ndi mtundu wa pulogalamu yothandizira.
Chenjezo: Kuyika woyenda dera kumaphatikizapo kugwira ntchito pafupi ndi zipangizo zonyamula zamakono zamagetsi. Ngakhale kuti madalaivala aakulu ndi maulendo onse a nthambi mu chipinda chautumiki adzatsekedwa kuti asungidwe kwa GFCI, otsogolera omwe akubwera kuchokera ku ntchito yothandiza ndi malo otsegulira otsala adzakhalabe ndi moyo nthawi zonse . Musakhudze mizere ya utumiki kapena mawotchi akuluakulu pamene mukugwira ntchito mu gulu la utumiki.
Kusankha Wokonza GFCI Wokongola
Mapulogalamu ogwira ntchito ndi ophulika amapangidwa ndi opanga opanga osiyanasiyana, ndipo mapepala ndi mapulogalamu osokonekera sizimagwirizana. Mukamagwiritsa ntchito pulogalamu yatsopano, phokoso liyenera kugwirizana ndi mtunduwo ndi mtundu umene uli nawo.
Onaninso zowonongeka ndi / kapena wopanga mapulani kuti ayankhe. Wopalamulayo ayenera kuti azikhala ndi mphamvu zoyenera komanso zoyenera kuti azitha kuyang'anira. Maulendo a nthambi a nthambi amawerengera ma volts 120 ndi 15 kapena 20 amps. Maulendo omwe amalembedwa amamita 15 amakhala ndi waya wowonjezeredwa 14 koma akhoza kukhala ndi wiringira 12; zonse ziloledwa.
Dera lamapikisano 15 liyenera kutetezedwa ndi mpweya wamakono 15. Maulendo oyendera ma ampita 20 ayenera kukhala ndi makina 12 kapena lalikulu wiringire ndipo ayenera kutetezedwa ndi mpweya wa 20-amp. Musagwiritse ntchito mpweya wamakono 20 pa circuit 15 amp amp.
Kusiyana pakati pa Standard ndi GFCI Breakers
Onse awiri ndi a GFCI amatha kukhala osasunthika omwe amagwira ntchito imodzi papepala lamtumiki ndikugwirizanitsa ndi waya wina wotentha, kawirikawiri waya wakuda. Kusiyanitsa kwakukulu pakati pa mitundu iwiri ya anthu osokonekera kumaphatikizapo kugwirizana kwa mbali. Pogwiritsa ntchito njira yowonongeka, waya wolowerera nawo mbali (kawirikawiri woyera) umagwirizanitsa ndi bwalo losalowerera mbali pazenera; sizimagwirizana ndi wosweka. Ndi wothandizira GFCI, waya wandale wosaloĊµerera umagwirizanitsa ndi malo osaloĊµerera m'ndendemo pamsana. Ambiri a GFCI amakhalanso ndi waya wofiira, wophimbidwa, wosawoneka woyera womwe umalowetsedwa pamsana; izi zimagwirizanitsa ndi basi yopanda ndale pamphindi.
Zindikirani: Muyenera kugwirizanitsa waya wothandizira ku malo otentha "otentha" kapena "katundu" pa GFCI yopuma ndi kulumikiza waya wandale osalowerera kupita kumalo osalowerera. Kusakaniza izi kumapangitsa kuti dera liziyenda bwino ndipo lingatanthauze kuti phokoso limapereka GFCI kuteteza dera-ngakhale ngati batani la tester likugwira ntchito moyenera.
Momwe Mungakhalire GFCI Breaker
Gawo lofunika kwambiri pa polojekitiyi ndilokutseka mphamvu ku chipangizo cha ntchito potsegula chotsitsa chachikulu . Izi zimachotsa mphamvu pazitsulo zotentha zamabasi ndi maofesi onse a nthambi. Silichotsa mphamvu kwa otsogolera othandizira mautumiki omwe amachokera kumagetsi omwe amagwiritsidwa ntchito kapena malo omwe amatha kugwiritsira ntchito pamtundu waukulu. Ma waya awa ndi malo osungira amakhalabe amoyo ndipo amanyamula zoopsa ngakhale pamene phokoso lalikulu likuchotsedwa. Musagwirizane ndi mawotchi akuluakulu kapena ma waya. Nazi njira zoyenera zowonjezera wodula GFCI watsopano pamalo otseguka pazowonjezera:
- Tsegulani chitseko cha pulogalamu ya utumiki ndikusintha chopumira chachikulu ku OFF.
- Chotsani chivundikiro cha panja ("chivundikiro chakufa chakutsogolo") popanda kuthana ndi waya uliwonse mkati mwa gululo.
- Onetsetsani kuti mphamvu imachoka mkati mwa gululo, pogwiritsa ntchito osayesa magetsi.
- Chotsani mbale imodzi yogogoda pa chivundikiro, ngati kuli koyenera, kuti mutsegule wotsegula GFCI watsopano.
- Sinthani mpweya watsopano wa GFCI kupita ku OFF position.
- Tsegulani waya wodutsa kupita ku "HOT" kapena "LOAD" zotsegula zotsegula pa GFCI.
- Lumikizani waya wandale osalowerera kupita ku "NEUTRAL" wotsegula piritsi pa GFCI.
- Lumikizani waya wothandizira wautali woyera wa GFCI wopita kumalo osayendetsa basi pamsewu wothandizira. Muyenera kugwiritsa ntchito galasi lotseguka pamabasi a basi; musagwirizane ndi waya woposa umodzi.
- Sungani mphungu wa GFCI m'phanelo monga momwe akuwonetsera ndi wopanga. Ambiri amatha kukhala ndi mphako kapena phazi kumapeto kwa mphukira yomwe imalowa mu sitima yowonongeka kumbali ya kunja kwa malo osokoneza. Mapeto a mkati amalowetsa mu tabu kapena pulogalamu pamakono otentha a basi.
- Bweretsani chivundikiro cha panja (ndi chitseko, ngati chikuyenera). Sinthani kusweka kwakukulu ku malo omwe akubwezeretsani mphamvu ku gululo.
- Yesani GFCI woswa motsogoleredwa ndi wopanga.
