Ingabe izibani namasokhethi kungaba kusekethe efanayo?

Ukuba nezibani namasokhethi kusekethe efanayo kungaba lula, kodwa ingabe ngokobuchwepheshe kungenzeka futhi kuyenzeka, futhi yini amakhodi kagesi ayincomayo?

Yiqiniso, kungenzeka ukuthi kube nezibani namasokhethi kumjikelezo ofanayo. Izinqamuli zesekethe zingasetshenziselwa kokubili ukukhanyisa namasokhethi inqobo nje uma isamba somthwalo singadluli u-80% wamandla azo alinganiselwe. Ngokuvamile, i-15 A circuit breaker ifakwe ukuze isetshenziswe ngokujwayelekile, engasetshenziswa kuzo zombili izinhloso ngesikhathi esisodwa. Nokho, lokhu kungase kungasebenzi, ikakhulukazi uma kusetshenziswa izintambo ezincane futhi uma kusetshenziswa izinto zikagesi ezidonsa imisinga ephezulu. Futhi, kungase kwenqatshelwe kwezinye izindawo. Uma ukwazi, hlukanisa amaqembu amabili amasekhethi ukuze kube lula.

Isincomo seNational Electrical Code (NEC): I-National Electrical Code (NEC) ivumela izibani namasokhethi ukuthi anikezwe amandla kusuka kusekethe efanayo, inqobo nje uma isekethe ilinganiswe kahle futhi ifakwe ukuvimbela ukugcwala ngokweqile nokuqinisekisa ukuphepha kwesistimu kagesi.

Ukuba khona kwezibani nezisekelo kumjikelezo ofanayo

Ukuba khona kwezibani nezisekelo kumjikelezo ofanayo kungenzeka ngobuchwepheshe.

Azikho izithiyo zobuchwepheshe kuzinto zakho zokulungisa namasokhethi usebenzisa isifunda esifanayo. Bangakwazi ukushintshanisa amaketanga kalula. Eqinisweni, kwakuyinto evamile engxenyeni yokuqala yama-20s.^th Ikhulu leminyaka, lapho amakhaya amaningi enemishini yasendlini elula kuphela futhi, ngokufanele, ukucindezeleka okuncane kumasekhethi kagesi. Ukuthi kufanele noma cha kungenye indaba.

Ngakho-ke, uma uthanda, ungasebenzisa umjikelezo ofanayo wokukhanyisa nezindawo zokuphuma zikagesi, inqobo nje uma ungabelani ngamasekhethi okukhanyisa nezinto zikagesi ezinamandla futhi amakhodi wakho wendawo akuvumela lokho.

Ngaphambi kokubheka izici zomthetho, ake sibheke ezinye izinzuzo kanye nokubi kuzo zombili izimo.

Izinzuzo nokungalungi

Kungaba ngcono ukucabangela izinzuzo nezingozi lapho unquma ukuthi uhlukanise noma uhlanganise ukukhanyisa kanye nezitolo zikagesi.

Inzuzo eyinhloko yokuwahlukanisa ukuthi kuyoba eshibhile ukufaka isifunda sokukhanyisa. Lokhu kungenxa yokuthi izibani zisebenzisa ugesi omncane kakhulu, ngakho ungasebenzisa izintambo ezincane kuwo wonke amasekhethi akho okukhanyisa. Ungasebenzisa izintambo eziwugqinsi ezitolo. Ngaphezu kwalokho, kunconywa ukuthi ungasebenzisi ama-circuits okukhanyisa avamile anemishini enamandla futhi usebenzise ama-circuits ahlukene kulabo abasebenzisa okwamanje kakhulu.

Ububi obukhulu bokuhlanganisa kokubili ukuthi uma uxhuma into esebenza kumjikelezo bese uthola ukugcwala ngokweqile, i-fuse nayo izophephetha bese ivala ukukhanya. Uma lokhu kwenzeka, kungase kudingeke ubhekane nenkinga ebumnyameni.

Kodwa-ke, uma unezintambo eziningi, ukugcina amasethi amabili ahlukene wamasekhethi ezintambo kungaba nzima noma kube nzima ngokungadingekile. Ukuze ugweme lesi simo, noma uma unendlu enkulu noma ikakhulukazi izinto zikagesi ezincane, ukuzihlanganisa akufanele kube yinkinga. Esinye isisombululo kungaba ukwakha amasokhethi ahlukene ezinto zakho zikagesi eziphakeme kuphela futhi, okungcono, ukuzihlelela amasekhethi azinikezele.

Kodwa-ke, kufanele kucace ukuthi ukuhlukanisa isifunda sokukhanyisa kusuka ezitolo, okuzovimbela noma iyiphi idivayisi noma umshini ukuthi uxhunywe kumjikelezo wokukhanyisa, kubiza kancane ukuhlela futhi kuyindlela ephephile futhi elula kakhulu.

Imithetho yendawo kanye nemithethonqubo

Amanye amakhodi endawo kanye nemithethonqubo inquma ukuthi uvunyelwe yini ukuba nezibani namasokhethi kusekethe efanayo.

Endaweni ethile kuvunyelwe, kodwa kwenye indawo hhayi. Uma kungekho mingcele, ungasebenzisa izikimu ezifanayo kuzo zombili izimo zokusebenzisa, noma usethe izikimu zokuxhuma ezihlukene ngayinye.

Kufanele uhlole amakhodi wakho wendawo kanye nemithethonqubo ukuze uthole ukuthi yini evunyelwe nokuthi yini engavunyelwe.

ukusetshenziswa kwamandla

Enye indlela yokubheka ukuthi ungakwazi yini noma kufanele ube nezibani namasokhethi kumasekhethi afanayo ukucabangela ukusetshenziswa kwamandla.

Ngokuvamile, i-circuit breaker engu-15 noma engu-20 amp ifakwa ukuze kuvikelwe amasekhethi enhloso evamile. Lokhu kusho ukuthi ungasebenzisa ngokuphephile amadivaysi nezinto zikagesi ezingadonsi ngaphezu kwama-amps ayi-12-16, ngokulandelana. Ungasebenzisa ngokuphephile izinto zokukhanyisa nezinye izinto zikagesi ndawonye, ​​kodwa kuphela inqobo nje uma isamba esisetshenziswa amandla singeqi umkhawulo wokusetshenziswa kwamandla.

Inkinga engaba khona yenzeka kuphela uma i-current idlula u-80% wesilinganiso se-circuit breaker.

Uma ungakwazi ukwabelana ngamasekhethi phakathi kokukhanyisa nezinto zikagesi ngaphandle kokweqa imikhawulo, ungaqhubeka nokwenza kanjalo ngenjabulo. Uma kungenjalo, uma kungenjalo, unezinketho ezilandelayo:

• Faka i-circuit breaker enesilinganiso esiphezulu ukuze uvumele ukusetshenziswa okuningi (akunconyiwe);
• Kungenjalo, amasekhethi ahlukene okukhanyisa nezisekelo zezinye izinto zikagesi;
• Okungcono nakakhulu, faka amasekhethi azinikele azo zonke izinto zakho zikagesi ezinamandla futhi ungawasebenzisi kumasekhethi okukhanyisa.

Ngokucabangela ubukhulu bekamelo

Umuntu osebenza ngogesi oqeqeshiwe angabhekana nalolu daba ngokucabangela nendawo ephansi noma ubukhulu begumbi ekhaya lakho.

Okokuqala, kufanele kuqashelwe ukuthi izinto ezisebenza ngamandla amakhulu njengama-ayina, amaphampu amanzi nemishini yokuwasha azifakiwe kulezi zibalo njengoba kufanele zibe kumasekethe ahlukene azinikezele. Uzodinga ukunquma indawo yegumbi ngalinye ekhaya lakho. Sizobe sesisebenzisa uMthetho we-3VA.

Isibonelo, igumbi elilinganiselwa ku-12 by 14 feet lihlanganisa indawo engu-12 x 14 = 168 square metres.

Manje phinda lokhu ngo-3 (umthetho we-3VA) ukuze unqume ukuthi igumbi lidinga amandla angakanani (ukusetshenziswa okuvamile): 168 x 3 = 504 watts.

Uma isifunda sakho sinokushintsha kwama-amp angu-20, futhi kucatshangwa ukuthi i-voltage yakho ye-mains ingu-120 volts, umkhawulo wamandla wetiyetha wesekethe ngu-20 x 120 = 2,400 watts.

Njengoba kufanele sisebenzise kuphela u-80% wamandla (ukuze singacindezeli isifunda), umkhawulo wangempela wamandla uzoba ngu-2,400 x 80% = 1,920 watts.

Ukusebenzisa umthetho we-3VA futhi, ukuhlukanisa ngo-3 kunikeza u-1920/3 = 640.

Ngakho-ke, isekethe yenhloso evamile evikelwe i-20 A breaker yanele indawo engamamitha-skwele angama-640. izinyawo, okungaphezu kwendawo ehlala amakamelo 12 by 14 (okungukuthi 168 sq. feet). Ngakho, uhlelo lufanelekile ekamelweni. Ungakwazi ngisho nokuhlanganisa izikimu zokumboza amakamelo angaphezu kwelilodwa.

Kungakhathaliseki ukuthi usebenzisa izibani, ezinye izisetshenziswa, izinto zikagesi, noma inhlanganisela yakho kokubili, inqobo nje uma ingqikithi yamandla asetshenziswayo ingeqi ama-watts angu-1,920, ungayisebenzisela izinhloso ezivamile ngaphandle kokuyilayisha kakhulu.

Imibuzo evame ukubuzwa

Mangaki amalambu nezitolo engingazisebenzisa?

Ungase uzibuze ukuthi mangaki amalambu namasokhethi ongawafaka, noma zingaki (injongo evamile) izisetshenziswa zikagesi nezinto zikagesi ongazisebenzisa ngesikhathi esisodwa.

Njengomthetho ojwayelekile, ungasebenzisa ngokuphepha ama-LED ama-2 kuya kwayi-3 ngesekethe eyi-15- noma engu-20-amp, njengoba isibani ngasinye ngokuvamile asidluli ama-watts angu-12-18. Lokhu kusafanele kushiye isikhala esanele sezinto zikagesi ezingabalulekile (ezingenamandla). Ngokuqondene nenani lemishini, kufanele usebenzise izinto ezingeqi isigamu sesilinganiso se-circuit breaker. Lokhu kusho ukuthi kufanele ucabangele cishe ishumi njengobukhulu kusekethe engu-20 amp kanye nesishiyagalombili kusekethe engu-15 amp.

Kodwa-ke, njengoba kuboniswe ngenhla ngezibalo, umuntu kufanele empeleni anake amandla aphelele asebenza ngesikhathi esifanayo, ukuze lamanje lingadluli u-80% womkhawulo wokuphula.

Yimuphi usayizi wezintambo okufanele usetshenziselwe umjikelezo wokukhanyisa?

Ngaphambilini ngishilo ukuthi izintambo ezincane kuphela ezidingekayo kumjikelezo wokukhanyisa, kodwa zingaba mncane kangakanani?

Ngokuvamile ungasebenzisa i-12 gauge wire kumasekhethi okukhanyisa angawodwana. Usayizi wentambo uzimele kusayizi we-breaker circuit, noma ngabe isekethe ye-amp engu-15 noma engu-20, njengoba ngokuvamile ngeke udinge okwengeziwe.

Ukufingqa

Ungakhathazeki ngokuhlanganisa ukukhanya namasokhethi kumasekhethi afanayo. Qiniseka ukuthi awusebenzisi noma yimaphi amadivayisi anamandla noma izinto zikagesi kuwo njengoba kufanele abe amasekhethi ahlukene azinikele. Kodwa-ke, ungahlukanisa amasekhethi okukhanyisa namasokhethi ngezinzuzo ezishiwo ngenhla.

Bheka ezinye zezihloko zethu ngezansi.

• Yini uhlelo oluhlanganisiwe
• Ingabe ngidinga iketango elihlukile lokuqoqwa kukadoti?
• Ingabe iphampu yokudonsa idinga isifunda esikhethekile
