Kunamakhodi kagesi okufanele alandelwe kunoma yikuphi ukufakwa kukagesi, kuhlanganise nokufakwa kukagesi ngaphandle.Uma kucatshangelwa izibani zangaphandle zingase zivezwe kuzo zonke izinhlobo zesimo sezulu, zenzelwe ukuvala umoya,imvula, neqhwa.Izinto eziningi zangaphandle nazo zinamakhava akhethekile okuvikela ukugcina ukukhanya kwakho kusebenza ezimeni ezimbi.
Izimpahla ezisetshenziswa ngaphandle kufanele zibe nesivikelo sokuphepha kusiphazamisi sesekethe esinephutha eliphansi.Amadivayisi e-GFCI ahamba ngokuzenzakalelayo uma ezwa ukungalingani kumjikelezo okungase kubonise iphutha phansi, okungenzeka umaimpahla kagesi nanoma ubani oyisebenzisayo uthintana namanzi.Izimpahla ze-GFCI zivame ukusetshenziswa ezindaweni ezimanzi, kufaka phakathi izindlu zangasese, izindlu zangasese, amakhishi, amagaraji, nangaphandle.
Ngezansi kunohlu lwezimfuneko ezithile zokukhanyisa kwangaphandle nezitolo kanye namasekhethi awaziphakelayo.
1.Izindawo Ezidingekayo Zezimpahla Zangaphandle
Izimpahla zangaphandle yigama elisemthethweni lezindawo zokukhipha ugesi ezijwayelekile—kuhlanganise nalezo ezifakwe ezindongeni zendlu yangaphandle.njengakumagaraji ahlukanisiwe, amadekhi, nezinye izakhiwo zangaphandle.Izithako nazo zingafakwa ezigxotsheni noma ezigxotsheni egcekeni.
●Zonke izinto ezingu-15-amp kanye ne-20-amp, 120-volt kumele zibe zivikelwe yi-GFCI.Ukuvikelwa kungase kuvele esitshalweni se-GFCI noma i-GFCI breaker.
●Kudingeka isitsha esisodwa ngaphambili nangemuva kwendlu futhi endaweni ephakeme ngamamitha angu-6 amayintshi angu-6 ngaphezu kwebanga (izinga eliphansi).
●Kudingeka isitsha esisodwa ngaphakathi kwepherimitha ye-balcony ngayinye, idekhi, uvulandi, noma ivulandi elifinyeleleka ngaphakathi kwekhaya.Lesi sitsha akumele sigxunyekwe ngaphezu kwamafidi angu-6 namayintshi angu-6 ngaphezu kwendawo yokuhamba ye-balcony, idekhi, ivulandi, noma ivulandi.
●Zonke izitsha ezingakhiyiwe ezingama-15-amp kanye ne-20-amp 120-volt ezindaweni ezimanzi noma ezimanzi kufanele zifakwe kuhlu njengohlobo olumelana nesimo sezulu.
2.Amabhokisi Okungena Kwangaphandle Namakhava
Izimpahla zangaphandle kufanele zifakwe emabhokisini kagesi akhethekile futhi zibe namakhava akhethekile, ngokusekelwe ohlotsheni lwangempela lokufakwa nendawo yazo.
●Wonke amabhokisi abekwe phezulu kufanele afakwe ohlwini ukuze asetshenziswe ngaphandle.Amabhokisi asezindaweni ezimanzi kufanele afakwe ohlwini lwezindawo ezimanzi.
●Amabhokisi ensimbi kufanele asekelwe phansi (umthetho ofanayo uyasebenza kuwo wonke amabhokisi ensimbi angaphakathi nangaphandle).
●Izithako ezifakwe ezindaweni eziswakeme (njengasodongeni oluvikelwe phezulu ngophahla lukavulandi noma enye imbobo) kufanele zibe nesembozo esingamelana nesimo sezulu esigunyazwe izindawo ezinomswakama (noma izindawo ezimanzi).
●Izimpahla ezitholakala ezindaweni ezimanzi (ezingavikelekile emvuleni) kufanele zibe nekhava "esetshenziswayo" elinganiselwe ezindaweni ezimanzi.Lolu hlobo lwekhava luvikela isitsha kumswakama ngisho nalapho intambo ixhunywe kuso.
3.Outdoor Lighting Izidingo
Izidingo zokukhanyisa kwangaphandle ziqondile futhi ngokuyisisekelo zihloselwe ukuqinisekisa ukufinyelela okuphephile nokulula ekhaya.Amakhaya amaningi anokukhanya kwangaphandle okuningi kunalokho okudingwa yi-NEC.Amagama athi "indawo yokukhanyisa" nelithi "luminaire" asetshenziswe ku-NEC kanye nemibhalo yekhodi yendawo ngokuvamile abhekisela ezimpahleni zokukhanya.
●Kudingeka indawo yokukhanyisa eyodwa ohlangothini lwangaphandle lwayo yonke iminyango yangaphandle ezingeni lebanga (iminyango yesitezi sokuqala).Ayifaki iminyango yegaraji esetshenziselwa ukungena kwemoto.
●Kudingeka indawo yokukhanyisa kuyo yonke iminyango yegaraji.
●Ama-transformer kumasistimu okukhanyisa ama-low-voltage kumele ahlale efinyeleleka.Ama-transformer ohlobo lwe-plug-in kufanele axhume esakhiweni esivikelwe nge-GFCI esinekhava "esetshenziswayo" elinganiselwe ezindaweni ezimanzi.
●Izinto ezikhanyayo zangaphandle ezindaweni ezinomswakama (ngaphansi kokuvikelwa kophahla noma i-eave overhang) kufanele zifakwe ohlwini lwezindawo ezimanzi (noma izindawo ezimanzi).
●Izinto ezikhanyayo ezindaweni ezimanzi (ngaphandle kokuvikelwa phezulu) kufanele zifakwe ohlwini lwezindawo ezimanzi.
4.Ukuletha Amandla Ezintweni Zangaphandle Nokukhanyisa
Amakhebuli esekethe asetshenziselwa okokugcina abekwe odongeni nezinto ezikhanyayo angagijima obondeni kanye nekhebula elivamile elingelona elensimbi, inqobo nje uma ikhebuli isendaweni eyomile futhi ivikelekile emonakalweni nakumswakama.Izimpahla zokwamukela izinto ezikude nendlu ngokuvamile ziphakelwa ngekhebula lesekethe elingaphansi komhlaba.
●Ikhebula ezindaweni ezimanzi noma ngaphansi komhlaba kufanele kube uhlobo lokuphakelayo ngaphansi komhlaba (UF-B).
●Ikhebula elingaphansi komhlaba kufanele lingcwatshwe okungenani amayintshi angu-24 ukujula, nakuba ukujula okungamayintshi angu-12 kungase kuvunyelwe kumasekhethi angu-20-amp noma amancane anomthamo wokuvikela we-GFCI.
●Ikhebula elingcwatshiwe kufanele livikelwe ngomsele ovunyelwe ukusuka ekujuleni okungamayintshi angu-18 (noma ukujula okudingekile kokungcwaba) ukuya kumafidi angu-8 ngaphezu komhlaba.Zonke izingxenye eziveziwe zekhebula le-UF kufanele zivikelwe ipayipi elivunyiwe.
●Ukuvuleka lapho ikhebula le-UF lingena khona epayipini elingeyona i-PVC kumele lifake ibhushi ukuze kuvinjelwe ukulimala kwentambo.
