Chimwe chikamu chinokanganisa circuit breaker chinonzi zvakakodzera pasi-mhosva-circuit breaker - breaker, kana kungoita GFCI breaker . Inopinda mubato rebasa reimba, kana bhokisi rinoputika, uye rinopa GFCI kuchengetedzwa kwebazi rose rebazi rinoshumira. Izvi zvinowanzoshandiswa seimwe nzira yekuisa GFCI midziyo (nzvimbo dzokutengeserana) mune dzimwe nzvimbo apo dzinodiwa nekombiji yemagetsi.
A GFCI breaker anoisa yakafanana neyeta-single-pole circuit breaker, asi pane zvimwe zvakasiyana zvakasiyana kuti uzive. Uyewo, mutadzi mutsva weGFCI anofanira kunge ari mukana wakakodzera uye marimi yepanepa yebasa.
Inyevero: Kuisa mutsigiri wedunhu kunosanganisira kushanda pedo nemidziyo inotakura zvinokonzera maitiro emagetsi. Kunyange zvazvo hurukuro huru yedunhu uye yese yezvikwata zvemapazi mubato rebasa ichavharwa nokuda kwekugadzirisa kweGFCI, vatariri vauya vanobva kubasa rekushandira uye zvigaro zvepamusoro pavanenge vadzidza vacharamba vachirarama nguva dzose . Usambobata pamigero yebasa kana kuti zvigaro zvemashure ekushandura paunenge uchishanda mubato rebasa.
Kusarudza Zvakarurama GFCI Breaker
Nzvimbo dzebasa nevanokonzera dzinoitwa nevakawanda vakasiyana-siyana, uye panels uye breakers hazvibvumirwi pasi rose. Paunenge uchitanga mutambi mutsva, mutumbi wacho unofanira kunge wakabatana nechirongwa uye chikwata chepaneji yaunayo.
Tsvaga muchengeti uye / kana panhizha muiti wezvirongwa. Muchiri mutsva anofanirawo kutakura mhepo yakakodzera uye kuenzanisa kwechikwata ichichadzivirira. Dunhu reruwa rebazi rakataridzirwa makumi maviri nemakumi maviri nemazana maviri kana makumi maviri. Nharaunda dzakarongerwa maawa 15 dzinowanzo dzine 14-gauge wiring asi inogona kunge ine 12-gauge wiring; zvose zvinotenderwa.
A-15-amp circuit inofanira kuchengetedzwa ne 15-amp breaker. Nhepfenyuro yakarongerwa makumi maviri emasipu inofanira kuva ne-12-gauge kana yakawanda yemajeri yemairi uye inofanira kudzivirirwa ne 20-amp breaker. Usamboshandisa 20-amp breaker pane 15-amp circuit.
Kusiyana Pakati Pakati Pakati neGFCI Breakers
Zvose zviri zviviri uye GFCI vacheche ndeye -single pole breaker s iyo inotora imwe slot pane panhare yebasa uye inonamatira kune imwe "inopisa" mutambo wedunhu, kazhinji tsvina yakasviba. Mhedzisiro huru pakati pemhando mbiri dzevanokanganisa inosanganisira kusagadzikana kwepakati. Nechipfuva chakasununguka, tambo dzisingatauri dzedunhu (kazhinji mutsvuku) dzinosanganiswa nejasi rebhasi risina kukwana pane panhare rebasa; hazvibatanidzi kune muchengeti. Neine GFCI breaker, tambo isina kutakura twero inosangana nechetachiona chekutakura kune imwe nzvimbo. Vakawanda veGFCI vanopindawo vane pfupi, yakavhenganiswa, yakachena yakasarura tambo yakasimudzwa pamusana; izvi zvinopindirana nebhasi risina kukwana pane panhizha.
Cherechedza: Unofanirwa kuisa tambo yekutya inotyisa kumusana we "hot" kana kuti "load" paGFCI breaker uye ubatanidze tambo dzisina kufambidzana dzedunhu kune zvisingatauri magetsi pajeri. Kusanganisa izvi kunodzokorora purodhiyo yedunhu uye zvinogona kureva kuti mutadzi haana kupa GFCI kudzivirirwa kune dunhu-kunyange kana bhatani romuedzo rinoshanda kazhinji.
Nzira yekugadzira GFCI Breaker
Nhanho inonyanya kukosha yeprojekti iyi iri kupfigira simba kumapanzura ebasa nekugadzirisa chinokonzera chikuru . Izvi zvinodzima simba kumapuranga emotokari emotokari uye kumatare ebazi ose. Icho hachibvisi simba kune vashandi vebasa rekushandira vanouya vachibva kumashandire emashandisirwo kana mamhedheni ayo vanopindirana nayo pane chikuru chakasara. Izvi zvinowanikwa uye zvigaro zvinoramba zvichirarama uye zvinotakura zvinouraya kunyange kana hurukuro huru ichidzimwa. Usambogunzva hurukuro dzinoshandiswa pamasiporesi kana mashare ekubatira. Heano matanho ekutanga ekuisa gadziriro itsva yeGFCI mune slot yakavhurika pane jeri rebasa:
- Vhura guriti rebasa rebasa uye shandura hurukuro yepamusoro kuO OFF position.
- Bvisa chivharo chepaneti ("chifukidziro chepamberi chakasara") pasina kubata chero mahwindo mukati mejeri.
- Iva nechokwadi chokuti simba racho riri mukati memapaneti, uchishandisa usingaiti mauto volter tester.
- Bvisa imwe yendepa dzekugogodza pavharivha yepanepa, kana zvichidikanwa, kuti ugadzire mukova weGFCI mutsva.
- Shandisa GFCI mutsva paI OFF position.
- Itai kuti mutambo weshondo unopisa uende ku "HOT" kana "LOAD" screw terminal paGFCI breaker.
- Gadzirai tambo dzisina kukodzera dzedunhu ku "NEUTRAL" screw terminal paGFCI breaker.
- Unganidza GFCI breaker's coiled white neutral tambo kune zvisingasviki bhasi pabhadhi rebasa. Iwe unofanirwa kushandisa svondo rakazaruka gumbo rebhasi; usabatanidza zvinopfuura tambo imwe kune imwe sara.
- Shandisa muchengeti weGFCI mujeri sezvinorayirwa nemugadziri. Vakawanda vanopisa vane chinyorwa kana netsoka pamucheto wekunze kwecheka rinopindira mumusara wekusimudza kune kunze kwekunze kwemafuro mubato rebasa. Mugumo wemukati wemukati unopinda mu tab kana chikwata pane bhenji rebhasi yebhasi.
- Dzorerai chivharo chepaneti (uye musuo, sezvinoshanda). Shandura chinokonzera chikuru kusvika paOI chinzvimbo chekudzorera simba kune jeri.
- Edza GFCI breaker sezvinorayirwa nemuiti.
