Zimakhala zachizoloŵezi kuti mabanja lero akhale ndi maulendo atatu omwe amapereka chipinda chochapa zovala. Yoyamba ndi dera la 20-amp kuti lipereke mphamvu ya 120-volt kwa makina otsuka. Yachiwiri ndi dera lopatulira 30 mamita yoyendetsa chowometsa cha magetsi. Wachitatu ndi dera loyendera magetsi okwana 15 lomwe limapereka magawo ofunika mu zipinda zina komanso malo ochapa zovala.
Wasamba Receptacle
Dera la 120-volt, 20m amphamvu limapereka chokwanira kwa makina ochapira.
Kawirikawiri amawombera ndi 12-gauge , waya wamphati awiri okhala ndi waya wotentha, waya wosalowerera, ndi waya wothira pansi. Cholandirira ndi GFCI 20-amphamvu (onani pansipa). Chofunika kwambiri pa dera ili ndikuti ndilo dera losankhidwa, kuti lisasokonezeke ndi dera lodzipereka . Pamene dera lopatulira limapereka kachipangizo kamodzi kokha, dera losankhidwa limapangidwira ntchito imodzi, osati chogwiritsira ntchito chimodzi. "Kugwiritsiridwa ntchito" pa nkhaniyi ndikochapa zovala, ndipo mukhoza kubudula onse ochapira ndi mpweya wa mpweya mumalo omwewo. Inde, ngati mwakhazikitsidwa kuti mupange mpweya wouma, simudzasowa chotsitsa cha 240-volt chomwe tidzakambirana.
Chotsitsa Chotseka
Zowonjezera zamagetsi zimayendera mphamvu zowonjezera 240 ndi voltage 120. 240V ndiyotengera gawo lotentha. 120V ndi ya timer, clock, buzzer, ndi mabelu ena ndi mluzu. Ngati mumagula zowonjezera zamagetsi lero, zidzasoweka chingwe chapadera chogwiritsira ntchito pulogi yamakina anayi.
Pulogalamuyi iyenera kugwiritsidwa ntchito ndi chokwanira 120 / 240V. Ndipo ndilo gawo lathu lotsatira lochapa zovala. Chotengera ichi chimaperekedwa ndi waya wa 10-gauge, waya wa waya atatu ndi mawaya otentha, waya wosalowerera, ndi waya wothira pansi. Deralo limatetezedwa ndi mamitala 30 amphamvu ozungulira dera. Okalemba okalamba amakhala ndi zingwe zitatu zomwe zimagwiritsidwa ntchito pazitsulo zitatu zokha.
Kuika izi sikuloledwa ndi Code National Electrical Code (NEC).
Dera la Kuunikira
Chipinda chochapa zovala chikanakhala chovuta kugwiritsa ntchito popanda dera loyatsa. Monga tanenera, zipinda zowonongeka m'zipinda zamatsuko zikhoza kukhala pa dera lomwelo monga kuyatsa kwa chipinda chapafupi kapena chipinda cholowera. Mipingo yowunikira kwambiri ndi ma-15 amp circuits ndipo nthawi zambiri imaphatikizapo zida zogwiritsira ntchito.
Chitetezo cha GFCI
NEC imafuna kuti GFCI (chitetezo chapakati pazitsulo) chizitetezedwe ku malo onse ogwiritsira ntchito opangira zovala. Izi zimaphatikizapo chokwanira cha 20-amp chotsitsa chasamba (ndi chowotcha mpweya, monga momwe zingagwiritsire ntchito) ndi zitsulo zomwe zimagwiritsidwa ntchito. Chitetezo cha GFCI sichifunika kuti pakhale chokwanira chakumapeto kwa magetsi 30 amphamvu.
Zosankha Zowonjezera
Pamene zipinda zatsamba zatsirizika ndi zowonjezera kapena zowonjezera zina, zitsulo zimayikidwa mumayendedwe apamwamba, ndi mabokosi a magetsi omwe amalowetsa khoma ndipo ndi NM chingwe chothamangira ku mabokosi. Mwinanso, zipinda zodyeramo m'zipinda zapansi kapena magalasi akhoza kukhala ndi konkire, konkire, kapena makoma osamalizidwa, pomwe mabotolo a magetsi angakhale okwera pamwamba. Izi zimafuna mabokosi achitsulo ndi waya wothandizira kupyolera muzitsulo (makamaka EMT).
M'malo mwa chingwe cha NM, womangayo angagwiritse ntchito zipangizo za THHN zokhazokha.
