Abantu benshi kandi benshi bitondera umutekano wamashanyarazi hanze mugihe bamara umwanya wo kuruhuka, kwidagadura no gukorera hanze.Kwizera umurongo wuzuye wibihe bya GFCI byakira neza nibyiza gushira imbere n'inyuma y'urugo rwawe kuri patios, etage na pisine hafi.Kugirango wuzuze kode, ibikoresho bigomba guhuzwa hamwe nuburyo bukwiye butarinda ikirere kugirango birinde byuzuye kubintu.
Ahantu hashobora guhangana n’ikirere hashobora gushyirwaho ahantu hatose cyangwa hatose ukurikije ibisabwa n’amategeko y’amashanyarazi y’igihugu (NEC®).Gereranya no guhura nikirere, kugirango ubone ibikoresho byinyongera mugihe-mu-gukoresha-ibifuniko bizaba amahitamo ya mbere cyane cyane mugihe ibicuruzwa bikoreshwa ahantu hacucitse nko ku rubaraza rutwikiriye nta guhura n’ikirere, urashobora gukoresha ibyangombwa byose byemewe ikirere kitarinda ikirere kugirango kirinde neza.
Niki gituma ikirere gisohoka ikirere-kirwanya?
Ibicuruzwa birwanya ikirere bigomba kurindwa kumuzunguruko wa GFCI mugihe bishobora no kuba urugero rwa GFCI.Ibicuruzwa birwanya ikirere bitandukanye nibisohoka mu nzu kugirango bihangane ningaruka zo guhura nibintu.Byakozwe hamwe na UV itajegajega, imiyoboro irwanya ruswa hamwe nigitambara cyo kwishyiriraho bityo bigahagarara kubintu bikaze byo hanze.Kwizera TRWR Ibicuruzwa byujuje ibisabwa na NEC Igice cya 406.8 * na UL kugirango bifashe kurinda umutekano no kurinda hanze.
Ahantu h’ikirere hashobora kubaho uburyo bwo guhangana na tamper hamwe na moderi ya GFCI kugirango bifashe kurinda umutekano wumuntu ndetse n’imihindagurikire y’ikirere ahantu hatose cyangwa hatose.
Kwizera Tamper-Resistant GFCI Ibicuruzwa bizana hamwe nuburyo bwubatswe bwimbere muri reseptacle birinda kugera kubitumanaho mubintu byinshi byamahanga, byemerera gusa gushiramo ibyuma bibiri cyangwa bitatu.Byombi Tamper-Resistant 15A GFCI yakira cyangwa 20A GFCI yakira ibyangombwa bisabwa na NEC iheruka kuva muri NEC 2017 na NEC 2020 kubicuruzwa bidashobora kwangirika mubituro ndetse n’ibigo byita ku bana.
WR Impamvu-Ikosa ryumuzunguruko (GFCI) Ahantu
Amashanyarazi yigihugu yigihugu® yubahiriza Ibihe birwanya GFCI Ibicuruzwa bitanga urwego rwo hejuru rwo kurinda amakosa yubutaka kubisabwa hanze.Ibicuruzwa bya GFCI nibikoresho byingenzi byumutekano bitanga uburinzi kubantu bahura namashanyarazi kubera amakosa-yubutaka.GFCIs ikurikirana ingufu z'amashanyarazi zigaburirwa ikintu cyose cyacometse hanze.Niba hagaragaye amakosa-yubutaka, "azimya" imbaraga kubintu mugice gito cyamasegonda, kugirango bifashe gukumira ibikomere cyangwa urupfu.
Iyo bigeze kumutekano wamashanyarazi wo hanze ya GFCI yakira cyangwa AFCI GFCI isohoka & reseptacle Combo, Kwizera Electric ifite ibifuniko bitemewe.Usibye gutura Ibihe-Kurwanya Ibidukikije hamwe nibipfundikizo birinda, dutanga ibyiciro bitandukanye byibitaro byihariye hamwe nubucuruzi bwa WR hamwe nubucuruzi butangiza ikirere kubisabwa byose.
Amatangazo ya NEC
Igice 406.8 gisaba ko ibintu byose bidafunze 15 amp na 20 amp 125 volt yakira ahantu hacucitse cyangwa ahantu huzuye hatarinda ikirere.
Icyiciro 406.9 Ibyakirwa ahantu hatose cyangwa huzuye (B) Ahantu hatose (1) Ibyakiriwe na Amperes 15 na 20 Ahantu Huzuye.Ibyakirwa bya amperes 15 na 20 zashyizwe ahantu huzuye amazi hagomba kuba hari uruzitiro rutarinda ikirere niba hashyizwemo agapira kamashanyarazi.
Agasanduku gasohoka gashyizwe kuri iyi ntego kazashyirwa ku rutonde kandi kagaragazwa nk '“imirimo y'inyongera.”Byose 15- na 20-ampere, 125- na 250-volt zidafunze ubwoko bwakirwa bugomba gushyirwa kurutonde rwubwoko bwihanganira ikirere.
