Pali ma code amagetsi omwe amayenera kutsatiridwa pakuyika kulikonse kwamagetsi, kuphatikiza magetsi akunja.Poganizira zowunikira zakunja zimatha kukumana ndi nyengo zamitundu yonse, zidapangidwa kuti zitseke mphepo,mvula, ndi matalala.Zida zambiri zakunja zimakhalanso ndi zotchingira zapadera zoteteza kuti kuwala kwanu kugwire ntchito pamavuto.
Zotengera zomwe zimagwiritsidwa ntchito panja ziyenera kukhala ndi chitetezo chotetezedwa ku zosokoneza zapansi.Zipangizo za GFCI zimayenda zokha ngati ziwona kusalinganika kwa dera komwe kungasonyeze vuto, lomwe lingachitikezida zamagetsi kapena aliyense amene akugwiritsa ntchito wakumana ndi madzi.Zotengera za GFCI nthawi zambiri zimagwiritsidwa ntchito m'malo onyowa, kuphatikiza zimbudzi, zipinda zapansi, khitchini, magalasi, ndi panja.
Pansipa pali mndandanda wazomwe zimafunikira pakuwunikira kwakunja ndi malo ogulitsira komanso mabwalo omwe amawadyetsa.
1.Malo Ofunika Panja Panja
Zotengera zakunja ndi dzina lovomerezeka la malo opangira magetsi okhazikika-kuphatikizanso omwe amayikidwa pamakoma akunja anyumba.monga m'magalasi otsekedwa, ma decks, ndi nyumba zina zakunja.Zotengera zimathanso kuyikidwa pamitengo kapena mizati pabwalo.
●Zotengera zonse za 15-amp ndi 20-amp, 120-volt ziyenera kukhala zotetezedwa ndi GFCI.Chitetezo chikhoza kubwera kuchokera ku chotengera cha GFCI kapena chophwanya GFCI.
●Chotengera chimodzi chimafunika kutsogolo ndi kumbuyo kwa nyumbayo komanso pamtunda wautali wa 6 mapazi mainchesi 6 pamwamba pa giredi (pansi).
●Chotengera chimodzi chimafunika mkati mwa khonde lililonse, khonde, khonde, kapena khonde lomwe limapezeka mkati mwa nyumbayo.Chotengerachi sichiyenera kukwezedwa pamwamba pa 6 mapazi 6 mainchesi pamwamba pa khonde, pakhonde, khonde, kapena khonde.
●Zotengera zonse za 15-amp ndi 20-amp 120-volt zosatseka m'malo onyowa kapena achinyezi ziyenera kulembedwa ngati mtundu wosamva nyengo.
2.Outdoor Receptacle Mabokosi ndi Zophimba
Zotengera zakunja ziyenera kuyikidwa m'mabokosi apadera amagetsi ndikukhala ndi zophimba zapadera, kutengera mtundu weniweni wa kukhazikitsa ndi malo awo.
●Mabokosi onse okwera pamwamba ayenera kulembedwa kuti agwiritsidwe ntchito panja.Mabokosi omwe ali m'malo onyowa ayenera kulembedwa m'malo onyowa.
●Mabokosi achitsulo ayenera kukhala pansi (lamulo lomwelo limagwira ntchito m'mabokosi azitsulo amkati ndi akunja).
●Zotengera zomwe zimayikidwa m'malo achinyezi (monga pakhoma lomwe limatetezedwa pamwamba ndi denga la khonde kapena chophimba china) ziyenera kukhala ndi chivundikiro chanyengo chomwe chimavomerezedwa m'malo achinyezi (kapena malo amvula).
●Zotengera zomwe zili pamalo amvula (zosatetezedwa ku mvula) ziyenera kukhala ndi chivundikiro "chogwiritsidwa ntchito" chovotera malo amvula.Chivundikiro chamtunduwu chimateteza chotengera ku chinyezi ngakhale chingwe chitayikemo.
3.Zofunikira Zowunikira Panja
Zofunikira pakuwunikira panja ndizowongoka ndipo zimapangidwira kuti zitsimikizire kuti nyumbayo ili yotetezeka komanso yosavuta.Nyumba zambiri zimakhala ndi zowunikira zambiri zakunja kuposa zomwe NEC imafunikira.Mawu oti "chowunikira" ndi "luminaire" omwe amagwiritsidwa ntchito mu NEC ndi zolemba zam'deralo nthawi zambiri amatanthauza zowunikira.
●Chowunikira chimodzi chimafunikira mbali yakunja ya zitseko zonse zakunja pamlingo wa giredi (zitseko zapansanjika yoyamba).Sizikuphatikizapo zitseko za garage zomwe zimagwiritsidwa ntchito polowera galimoto.
●Chowunikira chimafunikira pazitseko zonse za garage egress.
●Transformers pamagetsi otsika magetsi owunikira ayenera kukhala opezeka.Ma transformer amtundu wa pulagi akuyenera kulumikizidwa muchotengera chotetezedwa ndi GFCI chokhala ndi chivundikiro "chogwiritsidwa ntchito" chovotera malo amvula.
●Zowunikira panja m'malo achinyezi (motetezedwa ndi denga kapena padenga) ziyenera kulembedwa pamalo achinyezi (kapena malo amvula).
●Zowunikira m'malo onyowa (popanda chitetezo chapamwamba) ziyenera kulembedwa m'malo onyowa.
4.Kubweretsa Mphamvu ku Zotengera Zakunja ndi Kuwunikira
Zingwe zozungulira zomwe zimagwiritsidwa ntchito potengera zoyika pakhoma ndi zopangira zowunikira zimatha kuthamangitsidwa pakhoma ndi chingwe chokhazikika chosakhala chachitsulo, malinga ngati chingwecho chili pamalo owuma ndipo chimatetezedwa ku kuwonongeka ndi chinyezi.Zotengera ndi zomangira zomwe zili kutali ndi nyumbayo nthawi zambiri zimadyetsedwa ndi chingwe chapansi panthaka.
●Chingwe chonyowa kapena pansi pa nthaka chiyenera kukhala chamtundu wa pansi pa nthaka (UF-B).
●Chingwe chapansi pa nthaka chiyenera kukwiriridwa osachepera mainchesi 24, ngakhale kuya kwa mainchesi 12 kungaloledwe ku mabwalo 20-amp kapena ang'onoang'ono okhala ndi chitetezo cha GFCI.
●Chingwe chokwiriridwa chiyenera kutetezedwa ndi ngalande yovomerezeka kuchokera pakuya kwa mainchesi 18 (kapena kuzama kofunikira) mpaka 8 mapazi kuchokera pansi.Magawo onse owonekera a chingwe cha UF ayenera kutetezedwa ndi ngalande yovomerezeka.
●Kutsegula komwe chingwe cha UF chimalowera munjira yopanda PVC kuyenera kukhala ndi tchire kuti chiteteze kuwonongeka kwa chingwe.
