Nyaya dzakamuka nezvimwe zvitsva zvinodiwa muNFPA 70®, National Electrical Code® (NEC®), zvine chekuita neGFCI kuchengetedzwa kwenzvimbo dzekugara.Kutenderera kwekudzokorora kwe2020 edition yeNEC yaisanganisira kuwedzera kwakakosha kwezvinodikanwa izvi, izvo zvino zvawedzera kubatanidza midziyo inosvika 250V pamaseketi emapazi akatemerwa 150V kusvika pasi kana pasi, pamwe nemakamuri ese epasi (akapera kana kwete) uye ese ekunze. zvitoro (chigadziko kana kwete).Hapana mubvunzo kuti inspector ane basa rakakura kwazvo rekuona kuti zvinodiwa zvinowanikwa mu210.8 zvinoshandiswa nemazvo.
Zvakakodzera kuongorora kuti sei idzi dzokororo dzakaitwa pekutanga.Zvinodiwa zveGFCI zvinowanzoda zvikonzero zvakakura zvetekinoroji kuti itende kodhi yekugadzira kodhi kuti iwedzere zvishandiso zvitsva, zvishandiso, kana nzvimbo kune iyo rondedzero.Munguva yekudzokorora kutenderera kwe2020 NEC, kufa kwakati wandei kwakaunzwa sezvikonzero nei tichifanira kuwedzera kuchengetedza kweGFCI kuvanhu vari mudzimba.Mienzaniso yaisanganisira mushandi akabatwa nemagetsi neforemu ine simba yerudzi rwakaremara;mwana akabatwa nemagetsi achikambaira kuseri kwemushini wekuomesa achitsvaga katsi yake;uye mukomana wechidiki uyo akasangana panguva imwe chete neine simba re AC condensing unit uye necheni yakadzikama cheni apo aicheka nepakati pechivanze chemuvakidzani achienda kumba kunodya.Izvi zviitiko zvinosuruvarisa zvingadai zvakadziviswa dai GFCI yanga iri chikamu cheiyo equation.
Mubvunzo wakatosimudzwa maererano nezvinodiwa 250V ndewekuti ungakanganisa sei chigadziko chekugamuchira.Zvinodiwa zvekuchengetedzwa kweGFCI mukicheni hazvina kujeka sezvazviri munzvimbo dzisiri dzekugara.Chekutanga, zvigadziko zvakaisirwa kushandira kicheni countertops zvinofanirwa kuve GFCI yakachengetedzwa.Izvi hazvinyanyi kushanda kune zvigadziro zvemhando, sezvo izvo zvisingawanzo kuisirwa pahurefu hwe countertop.Kunyangwe dai vaive, zvakadaro, nyaya yacho yaigona kuitwa kuti zvigadziro zviripo kuti zvishandire huwandu uye hapana chimwe chinhu.Zvimwe zvinyorwa zvinyorwa mu 210.8 (A) zvingada kuchengetedzwa kweGFCI kune zvigadziro zvakasiyana-siyana zvinonyura, apo nzvimbo yekugamuchira inoiswa mukati memakumbo matanhatu epamusoro mukati memucheto wembiya yekunyura.Iyo renji yekugashira inongoda kuchengetedzwa kweGFCI kana ikaiswa mukati meiyi 6-foot zone.
Nekudaro, kune dzimwe nzvimbo dzekugara umo nyaya yacho yakati chechetere, senge nzvimbo yekuwachira.Iko hakuna madaro ane mirau munzvimbo idzodzo: kana chigadziko chakaiswa muimba yekuwachira/nzvimbo, inoda kuchengetedzwa kweGFCI.Naizvozvo, maomesa embatya ave kudikanwa kuve GFCI akachengetedzwa nekuti ari munzvimbo yekuwachira.Izvi zvakafanana kune dzimba dzepasi;ye2020 edition, iyo kodhi yekugadzira kodhi yakabvisa iyo "isina kupera" zvikwaniriso kubva mudzimba dzepasi.Iyo garaji ndiyo imwe nharaunda inotenderedza zvese, zvakare, zvichireva kuti welders, air compressors, uye chero imwe magetsi-powered chishandiso kana mudziyo waungawana mugaraji uchada GFCI dziviriro kana dziri tambo-uye-plug yakabatana.
Chekupedzisira, iyo GFCI yekuwedzera inogamuchira iyo yakanyanya kukurukurwa ndeyekuwedzera kwekunze kwekunze.Ziva kuti handina kuti "yekunze yekubira midziyo" -iyo yakanga yatovharwa.Uku kuwedzera kutsva kunosvika kumidziyo yakaomeswa zvakare, kunze kwemidziyo yekunyungudusa sinou uye nzvimbo dzekuvhenekesa.Izvi zvinoreva kuti iyo condenser unit yeair conditioner inoda kuve GFCI yakachengetedzwa, zvakare.Kana ichi chitsva chinodiwa chatanga kuitwa mukumisikidzwa kutsva, zvakabva zvabuda pachena kuti paive nenyaya neimwe mini-split ductless masisitimu anoshandisa magetsi-anoshandura midziyo yekudzora kumhanya kwecompressor uye inogona kukonzera kutsika kweGFCI dziviriro. .Nekuda kweizvi, NEC iri kugadzirisa a Tentative Interim Amendment on 210.8(F) kuitira kuti inonoke kuitwa kwemamini-split masisitimu aya kusvika Ndira 1, 2023. Iyi TIA parizvino iri muchikamu chekupa pfungwa dzevanhu isati yadzokera ku. komiti yekuongorora nekuita.Sangano reTIA rinoburitsa pachena kuti komiti iyi ichiri kutsigira kuchengetedzwa kwezvitoro izvi, asi inongoda kupa indasitiri imwe nguva yekuti igadzirise nyaya iyi yezvikwata zvakanangana izvi.
Nezvese idzi shanduko dzakakosha kune zvinodiwa neGFCI, zvinogona kuvimbiswa kuti 2023 revision kutenderera ichaona basa rakawanda richiitwa kutenderedza midziyo inoponesa hupenyu.Kuramba uchimhanya nenhaurirano hakungobatsiri hurongwa hwekuvandudza kodhi, zvinozobatsirawo kuti NEC igamuchirwe mune mamwe masimba munyika yose.
