Ezweni lokufakwa kukagesi, amagama athi “isitebhisi sekhebula le-NEMA” kanye “Ithreyi yekhebula le-NEMA"izincazelo" zivame ukukhulunywa ngazo. Le mibono ibalulekile ekuqinisekiseni ukuphathwa kwekhebula okuphephile nokuphumelelayo ezindaweni ezahlukahlukene, kusukela ezindaweni zezimboni kuya ezakhiweni zezentengiselwano. Lesi sihloko sizohlola ukuthi iyini ileli yekhebula le-NEMA futhi sikhanyise ngezincazelo zethreyi yekhebula le-NEMA.
KuyiniIlede lekhebula le-NEMA?
Iladi lekhebula le-NEMA uhlobo lohlelo lokuphatha ikhebula olusetshenziselwa ukusekela nokuhlela izintambo. Igama elithi “NEMA” limelela iNational Electrical Manufacturers Association (NEMA), ebeka izindinganiso zemishini kagesi kanye nezingxenye e-United States. Amaladi ekhebula le-NEMA ngokuvamile enziwa ngezinto ezifana ne-aluminium noma insimbi futhi aklanyelwe ukuhlinzeka ngohlaka oluqinile lokuqondisa nokubopha izintambo.
Imiklamo yeladi yekhebula le-NEMA inezitebhisi noma imigoqo evulela izintambo evumela izintambo ukuthi zilale phansi, okunciphisa ukucindezeleka kanye nomonakalo ongaba khona. Lo mklamo usebenza kahle kakhulu lapho izintambo zidinga ukugijinywa amabanga amade noma ezindaweni ezinobuningi bezintambo. Isakhiwo esivulekile seladi yekhebula siphinde sikhuthaze ukujikeleza komoya, sisize ekuqedeni ukushisa okubangelwa yizintambo, ngaleyo ndlela kuthuthukiswe ukuphepha nokusebenza.
Ukubaluleka Kwezindinganiso ze-NEMA
Izindinganiso ze-NEMA zidlala indima ebalulekile ekuqinisekiseni ukuthi imishini kagesi, okuhlanganisa amaladi ekhebula namathileyi, ihlangabezana nezindinganiso ezithile zokuphepha nokusebenza. Lezi zindinganiso zakhiwa ngokuvumelana phakathi kwabakhiqizi, abasebenzisi, kanye nabanye abathintekayo embonini kagesi. Ngokuhambisana nezindinganiso ze-NEMA, abakhiqizi bangaqinisekisa ukuthi imikhiqizo yabo ithembekile, iphephile, futhi iyahambisana nezinye izingxenye zikagesi.
KuyiniIkhodi ye-NEMA yethreyi yekhebula?
Imininingwane ye-NEMA yamathreyi ekhebula ichazwe ku-NEMA VE 2 standard, enikeza isiqondiso sokuklama, ukwakhiwa, kanye nokufakwa kwamathreyi ekhebula. Le standard ibalulekile ekuqinisekiseni ukuthi amathreyi ekhebula angasekela ngokuphephile isisindo sezintambo ngenkathi ehlinzeka ngokuvikelwa okwanele ezicini zemvelo ezifana nomswakama, uthuli, kanye nomonakalo ongokwenyama.
Izinga le-NEMA VE 2 lihlukanisa amathreyi ekhebula ngezinhlobo ezahlukene, kufaka phakathi amathreyi ezitebhisi, amathreyi aphansi aqinile, kanye namathreyi okufaka. Uhlobo ngalunye lunezinhlelo zokusebenza nezinzuzo ezithile, kuye ngendawo yokufaka kanye nohlobo lwekhebula elisetshenzisiwe. Isibonelo, amathreyi ezitebhisi afaneleka kakhulu ezinhlelweni zokusebenza ezisindayo ezidinga ukusekela inani elikhulu lamakhebula, kuyilapho amathreyi aphansi aqinile efanelekile kangcono ezindaweni lapho uthuli kanye nemfucumfucu kuyinkinga khona.
Lapho ukhetha futhi ufaka amaladi namathileyi ekhebula le-NEMA, izici eziningana kufanele zicatshangelwe:
1. **Umthamo Wesisindo**: Qiniseka ukuthi ileli yekhebula noma ithreyi yekhebula ingasekela isisindo sezintambo ezifakwayo. Lokhu kuhlanganisa ukucabangela isisindo sezintambo ngokwazo kanye nezinye izici ezifana nezimo zemvelo.
2. **Ukukhetha Izinto**: Khetha izinto ezifanele indawo ezizofakwa kuyo. Isibonelo, endaweni egqwalayo, i-aluminium ingaba yizinto ezikhethwayo; kanti insimbi ingase ifaneleke kakhulu ekusetshenzisweni kwemisebenzi enzima.
3. **Ihambisana ne-NEMA**: Njalo bhekisa indinganiso ye-NEMA VE 2 ukuqinisekisa ukuthi uhlelo lwethreyi yekhebula luhlangabezana nazo zonke izidingo zokuphepha nokusebenza ezidingekayo.
4. **Imikhuba Yokufaka**: Landela imikhuba emihle yokufaka ukuqinisekisa ukuthi amaladi noma amathreyi ekhebula afakwe kahle futhi izintambo ziqondiswe kahle futhi ziboshwe kahle.
Izitebhisi zekhebula ze-NEMAkanye nemininingwane yethreyi yekhebula le-NEMA ibalulekile ekuphathweni kwekhebula okuphumelelayo ekufakweni kukagesi. Ngokuqonda imininingwane nezindinganiso ezibekwe yi-NEMA, ochwepheshe bangaqinisekisa ukuthi ukufakwa kwabo kuphephile, kusebenza kahle, futhi kuhambisana nemithethonqubo yemboni. Kungakhathaliseki ukuthi kusezindaweni zezimboni, zezentengiselwano, noma zokuhlala, ukusetshenziswa kahle kwezitebhisi zekhebula le-NEMA namathreyi kungakhulisa kakhulu ukuthembeka nokuphila kwesikhathi kwezinhlelo zikagesi.
