Makompyuta a nyumba ali ndi mawaya odyetsa omwe amapereka mphamvu ku maofesi ndi nthambi ndi nthambi zomwe zimachokera kuzipangizo zamagetsi. Monga momwe mukudziwira, othandizira mauthenga akugwirizanitsa ndi chimbudzi chachikulu, chomwe chimapatsa mphamvu magetsi kuti aperekedwe. Nthawi zambiri zimagwirizanitsidwa ndi chipinda chozungulira cha 100 kapena 200 amphamvu, Chotsitsa chachikulu ndicho chotsutsana kwambiri ndi magetsi a bokosi losweka.
Palinso anthu ena ambiri omwe amachoka mkati mwa bokosi loyandikana nalo. Mitunduyi imasiyanasiyana ndi mapulogalamu omwe amagwiritsidwa ntchito pa 15 ndi 20-ampger amphamvu kwa omwe amatha kupitirira 100 amps kapena kuposa, malinga ndi kukula kwa chotsitsa chachikulu ndi zofunika zofunika pa dera lililonse. Mitundu imeneyi imabweranso m'modzi ((maulendo 120-volt) ndi miyendo iwiri (kwa 240 volt application). Ndiwo zipangizo zamakono zotetezera maulendo omwe amadyetsa madera, zipangizo monga zipangizo.
Kufotokozedwa kwa maulendo
Maulendo ambiri omwe ali m'nyumba mwanu ali ma circuits 15, 20-, kapena 30 amp amp. Zili mkati mwa gulu lanu la magetsi. Koma gulu lamagetsi ndi liti? Gulu lamagetsi la magawo a magetsi ndilo gawo lalikulu lofalitsira maulendo a magetsi kunyumba kwanu. Nthawi zambiri zimapereka mphamvu pakati pa 100 ndi 200 amphamvu kunyumba kwanu, malingana ndi zofuna zanu.
Mphamvu imabwera kunyumba kwanu kuchokera ku kampani yogwiritsira ntchito, kudzera mulowemo wautumiki. Amayenda kudzera mumagetsi, kupyolera mwa magetsi otsala ndiyeno kumalo osokoneza magetsi.
Dera loyendetsa magetsi ndilo kuchuluka kwa mphamvu zomwe nyumba yanu idzagwiritsa ntchito.
Kuti muone momwe ntchito yaikulu yamagetsi ikufunira kunyumba kwanu, munthu ayenera kuchita masewera apanyumba. Nyumba zokalamba nthawi zambiri zinkakhala ndi magetsi amphamvu okwana 60, zogwirizana ndi gulu la fuse. Ine kwenikweni ndinkakhala mu imodzi yomwe inali ndi 120-volts yokha yomwe ikulowa mmenemo. Ndiko kulondola, palibe msonkhano wa 240-volt! Tsopano nyumba zili ndi magetsi opita 100 kapena 200 amp amp amphamvu. Muyenera kudziwa katundu wa zipangizo zanu mu khitchini yanu kuti muphike kuti muyambe bwino kuika mipiringidzo yoyenera ndi oyendayenda.
Panel
Gulu lanu la magetsi liri wodzaza ndi zowonongeka, kuthamanga kuyambira pamwamba mpaka pansi pa gulu la utumiki. Mabala osadziwikawa ali kumbali ya kumanzere ndipo ngakhale oyendayenda omwe akuwerengedwa ali kumanja. Pamwamba pa anthu ambiri ozungulira dera ndikuthamanga kwina kwakukulu komwe kumagwiritsidwa ntchito kutsegula mbali yonse ya dera lakutulukira. Iwo amadziwika kuti ndi wosweka kwambiri. Zikuwoneka kuti ndizofunikira kwambiri mu gawo lonse lothawa. Imeneyi ndi njira yothetsera gulu lonselo. Koma mukhoza kufunsa chomwe chimapangitsa kuti zikhale zosiyana ndi ena onse ozungulira dera lomwelo.
Otsogolera oyendetsa nthambi ndi osachepera pokhazikika pa kukula ndi kukula. Pali chiwerengero chocheperapo kuchokera pa maulendo osapitirira 600 volts.
Zowonongeka izi zikulembedwa mu Code National Electrical Code (NEC) pansi pa mutu 210.19 (C).
Otsogolera oyendetsa magulu a nthambi amapereka mipangidwe ya nyumba, maofesi ophimbidwa ndi makoma ophikira ophikira, ndi zipangizo zina zapakhomo zapakhomo zimakhala ndi mphamvu zopanda malire a maofesi a nthambi komanso osachepera kuchuluka kwa katundu omwe angatumikidwe. Pa mzere wa 8 ¾ KW kapena mlingo wochulukirapo, chiwerengero chochepa cha nthambi-circuit adzakhala 40 amperes.
