Tiyeni tiyambe ndi tanthauzo la mawu kotero tonse tiri pa tsamba limodzi. Mtundu wina, womwe nthawi zina umatchedwa chitovu, ndilo chipangizo chimodzi chomwe chimakhala ndi uvuni ndi poto. Pali mitsinje yowonongeka, yomwe imalowa mu chokwanira, ndipo pali mitsinje yowonongeka, yomwe nthawi zambiri imakhala yowuma (osatsegulidwa). Mipikisano ya magetsi imaperekedwa ndi zotengera 120/240-volt. Akufunikira utumiki wa volt-120 wa timers, sensors, buzzers, ndi 240-volt utumiki wa zotentha ndi zotentha.
Maulendo ambiri osiyanasiyana ndi 50 amp amp, koma izi zingasinthe malinga ndi zofunikira. Zomwe sizingasinthe ndi mtundu wolandirira: kuyambira 1996, National Electrical Code (NEC) imafuna maulendo a magetsi a magetsi, mavuni, ndi zophika. Izi zikutanthauza kuti cholandiracho chiri ndi malo okwana anayi kuti avomere phukusi la chingwe cha 4-prong . Ndi kuphwanya code kukhazikitsa chokwanira chatsopano chomwe chimapangidwa ndi zingwe zapa-prong zakale.
Pulosi ya 3 vs. 4-Prong
Mapangidwe ndi makina ochapa zovala ali ndi nkhani yofanana. Zaka zisanafike chaka cha 1996 (zinalidi pafupi ndi 2000 pamene malamulo atsopano adalandiridwa), magetsi ndi zowuma zinkakonzedwa ndi otsogolera atatu: "malo" awiri komanso osalowerera ndale. Thupi lamagetsi, kapena ngongole, linakhazikitsidwa mwa kulowerera ndale kuti chingwe chowumitsa ndi chotengera chisakhale ndi malo osiyana. Pambuyo pa kusintha, zipangizo zinayamba kugulitsidwa ndi malo osiyana ndi osalowerera ndale. Kukonzekera uku kumafuna chingwe cha mphamvu cha conductor 4 chomwe chili ndi waya wosiyana womwe umagwirizanitsa ndi zida zowonjezera.
Machitidwe akale amagwira ntchito bwino, koma dongosolo latsopano ndilobwino.
Zolemba Zambiri za Grandfathered
Pamene tili pamutu wa zingwe zitatu ndi zowonjezera 4, muyenera kudziwa kuti NEC imalola kugwiritsa ntchito zipangizo zitatu zomwe zimagwiritsidwa ntchito ndi zingwe zakale. Ulamulilo wa otsogolera 4 ukugwiritsidwa ntchito pokhapokha pakuika zatsopano.
Ngati mukuwerenga izi chifukwa muli ndi chipinda chakale cha 3 koma mutagula chingwe chatsopano chomwe chimakonzedwa ndi chingwe cha 4-prong, mungathe kukhazikitsa chingwe cha 3-mmalo mmalo mochotsa chokwanira chanu chakale. Komabe, muyenera kukonza ma wiring osiyanasiyana kotero kuti nkhaniyo imangirizidwa kumalo osalowerera ndale. Mitundu yambiri imagulitsidwa ndi chidutswa chogwiritsira ntchito zitsulo kapena waya kuti achite zimenezo. Fufuzani buku la mwiniwake kapena wopanga mauthengawo kuti awathandize.
Zofunikira za Amperage ndi Malangizo
NEC ili ndi malamulo osiyana a mitundu yosiyana siyana. Mipangidwe yowonongeka kawirikawiri imakhala yovuta, ndipo oyendetsa madera amayenera kukhala ofunika chifukwa cha madzi omwe amatchulidwa ndi apulogalamuyo. Maulendo a mapulogalamu ogwiritsira ntchito plug-in akhoza kwenikweni kukhala otsikirapo kusiyana ndi mayina a dzina. Ngati chiwerengerocho ndi 12,000 watts kapena osachepera, dera lingapangidwe ma Watts 8,000. Izi zikutanthawuza kuti mungathe kupereka chipangizo chatsopano ndi chingwe cha AWG ndi mphindi 40, kusiyana ndi 6 AWG ndi 50-amp breaker. Nkhumba imapereka mwayiwu chifukwa chakuti chizindikiro cha dzinaplate chimachokera ku uvuni ndi zotentha zonse pokhala pamwamba pa nthawi yomweyo, zomwe sizichitika nthawi zambiri. Koma ngati munayamba mwalandira chakudya chambiri, mukudziwa kuti kuwombera zonse mwakamodzi, komanso kwa nthawi yaitali, sizowona.
Choncho, ndizozoloŵera bwino kupanga dera lozungulira ndi 50-amp breaker ndi 6 AWG conducors.
Malo Okhazikitsa Zojambula
Chombo chogwiritsira ntchito magetsi chingakhale bokosi lapamwamba kapena chokwanira chokwanira choikapo m'bokosi losungunuka. Mtundu uliwonse wa bokosi uyenera kukhala waukulu kwa otsogolera omwe mukuwagwiritsa ntchito. Mpaka 50m amphamvu amayendera foni ya 6-3 NM-B (w / ground) yamkuwa ndi chokwanira cha 50-amp, 4.
Malo a cholandira nthawi zambiri amatsimikiziridwa ndi wothandizira. Zimene zimagwiritsidwa ntchito pazigawo zowonongeka zimapezeka mosavuta kudzera kutseguka kumbuyo kwake. Nthawi ikafika pakutha, mumachoka ndikuchotseratu kanema pansi pa uvuni, kenaka mufike pamtunda kuchokera kutsogolo kuti mufike ku cholandira. Choncho, ndi bwino kukwera chokwanira chotsatira malingaliro a wopanga.
Kawirikawiri izi ziri kumbuyo kumbuyo (kapena nthawi zina pansi) kumbuyo kwazitali, masentimita angapo pamwamba pa pansi ndi kwinakwake mu malo a cabinet kuti muyambe.
