Ndi malo angati omwe ali pamakina a 15 amp?

Zikafika pa wiring m'nyumba mwanu, muyenera kuwonetsetsa kuti muli ndi nambala yolondola ya malo ogulitsira ndi ma switch. Umu ndi kuchuluka kwa ma amps anu 15 amp circuit breaker ayenera kukwanitsa.

Ngakhale kuti palibe malire pa chiwerengero cha malo omwe mungathe kugwirizanitsa ndi woyendetsa dera, ndibwino kuti muyike nambala yovomerezeka yokha. Zomwe tikulimbikitsidwa pamalonda ndi 1.5 amps. Chifukwa chake, ngati mukufuna kugwiritsa ntchito 80% yokha ya zomwe wophwanya dera lanu angakwanitse, simuyenera kukhala ndi malo opitilira 8.

Lamuloli la 80% limapezeka mu National Electrical Code (NEC) ndipo limagwira ntchito pa katundu wokhazikika. Izi ndizo katundu zomwe zimakhala zofanana kwa maola atatu kapena kuposerapo. Wowononga dera lanu atha kugwiritsidwa ntchito mpaka 3% yanthawiyo, koma kwakanthawi kochepa.

Kodi cholinga chochepetsa kuchuluka kwa malo ogulitsira pa circuit breaker ndi chiyani?

A 15 amp circuit breaker amatha kukhala ndi malo ambiri momwe mukufunira, koma mutha kugwiritsa ntchito zina panthawi imodzi. Izi ndichifukwa choti dera lanu limatha kugwira mpaka ma amps 15. Mukalumikiza chitsulo cha 10 amp ndi 10 amp toaster nthawi yomweyo, kuchulukirako kumayendetsa wophwanya dera.

Gwiritsani ntchito masiwichi osiyanasiyana pagawo lililonse la nyumba yanu kuti izi zisachitike. Kutengera mphamvu zomwe mukuganiza kuti chipinda chilichonse chidzafunika, mutha kugwiritsa ntchito 15 amp kapena 20 amp circuit breaker ndi kukula kwa waya.

Zowononga zozungulira ndizofunikira kuti nyumba yanu kapena nyumba yanu ikhale yotetezeka. Ophwanya ma circuit sichitetezo chokha panyumba iliyonse, komanso amafunikiranso ndi lamulo kuti aletse kudzaza kwamagetsi ndi moto. Komanso, nyumba yanu iyenera kukhala ndi zozungulira zoposerapo kuti mupewe kudzaza dera limodzi ndi zida zambiri.

Ndi malo angati omwe angakhalepo pozungulira?

NEC nthawi zina imalola kuti dera liziyenda ndi mphamvu zonse za wophwanya dera. Izi zili choncho chifukwa kuyenda kosalekeza kwa mphamvu yaikulu yotereyi kudzera mu mawaya kungakhale koopsa.

Kuthamanga ndi mphamvu zonse kumatenthetsa mawaya ozungulira, omwe amatha kusungunula kapena kuwononga kutsekemera kuzungulira mawaya. Kuchita zimenezi kungayambitse kuyendayenda kwafupipafupi, komwe kungayambitse moto kapena kugwedezeka kwamagetsi, zomwe zingakhale zakupha.

Mutha kuyendetsa mabwalo anu pamagetsi othamanga kwambiri kwakanthawi kochepa. NEC ikunena kuti nthawi zambiri nthawi yochepa imakhala maola atatu kapena kuchepera. Ngati ndiutali, mukuphwanya malamulo amagetsi ndikuika pangozi nyumba yanu ndi banja lanu.

Chifukwa china chomwe malirewo ndi 80% ya mphamvu zonse za ophwanya dera ndichifukwa NEC imakhulupirira kuti anthu omwe amadzaza malo opangira magetsi akuwonjezera zinthu zambiri kuchokera pamalo amodzi.

Pogwiritsa ntchito njira yomwe ili pansipa, mutha kuwerengera kuchuluka kwa malo omwe mungakhale nawo mu 15 amp circuit osapitirira 80% ya malire a katundu.

(15 A x 0.8) / 1.5 = 8 malo

Anthu ena omwe amapanga mapulagi ambiri kapena mapulagi owonjezera amawonjezera chitetezo kwa iwo, pomwe ena satero. Mapulagiwa amatha kudzaza dera ndikuphwanya malamulo amagetsi podutsa pakali pano mopitilira malire a 80% kudzera pamagetsi ozungulira.

Mumadziwa bwanji kuti mukulemetsa dera?

Kupatula chizindikiro chodziwika bwino cha 15 amp circuit breaker yomwe imayenda pafupipafupi, mumadziwa bwanji ngati mukudzaza dera pogwiritsa ntchito zida zambiri nthawi imodzi?

Masamu osavuta adzakuthandizani kupeza yankho. Watts wogawidwa ndi Volts amapereka unit Ampere. Nyumba zambiri zimayenda pa 120 volt AC, kotero timadziwa magetsi. Gwiritsani ntchito equation yotsatirayi kuti muwerenge kuchuluka kwa ma watts omwe tingagwiritse ntchito pozungulira.

15 amps = W / 120 volts

W = 15 amps x 120 volts

Mphamvu yayikulu = 1800W

Ndi formula iyi, titha kudziwa kuti ndi ma watt angati omwe dera limodzi lingagwire. Koma titha kugwiritsa ntchito mpaka 80% ya zomwe wophwanya dera amatha kuchita. Mutha kuzimvetsa mwa:

1800 x 0.8 = 1440 W

Zowerengera zathu zikuwonetsa kuti 1440 W ndiye mphamvu yayikulu yomwe ingagwiritsidwe ntchito pozungulira kwa nthawi yayitali. Ngati muwonjezera mphamvu ya chilichonse cholumikizidwa ndi socket iliyonse, mphamvu yonse iyenera kukhala yochepera 1440 watts.

Ndani ali ndi malo ogulitsira ambiri: 15 amp circuit kapena 20 amp circuit?

Malamulo omwewo angagwiritsidwe ntchito kudziwa momwe mungawerengere dera la 20 amp. Dera la 20 amp lidavoteredwa kuti likhale laposachedwa kuposa 15 amp circuit.

Zomwezo 80% za mphamvu zazikulu za ophwanya dera zili pa 20A, kotero malo khumi ndi okwera omwe angakhale pa dera lino. Chifukwa chake dera la 20 amp litha kukhala ndi malo ogulitsira ambiri kuposa 15 amp circuit.

Pogwiritsa ntchito lamulo lomwelo kuti pa 1.5 A iliyonse yomwe wophwanya dera angayigwire, payenera kukhala njira imodzi, mutha kufika paziganizo zotsatirazi:

(20 A x 0.8) / 1.5 = 10 malo

Kodi magetsi ndi soketi zitha kukhala pagawo limodzi?

Mwaukadaulo, mutha kuyendetsa magetsi ndi masiketi pagawo lomwelo. Wowononga dera sadziwa kusiyana pakati pa zitsulo ndi nyali; zimangoyang'ana kuchuluka kwa magetsi omwe akugwiritsidwa ntchito.

Ngati mukuwonjezera magetsi pamaketani otuluka, muyenera kuchepetsa kuchuluka kwa zotuluka ndi kuchuluka kwa magetsi omwe mukuwonjezera. Mwachitsanzo, ngati muwonjeza magetsi awiri kudera la 15A, mutha kukhala ndi masiketi asanu ndi limodzi muderali.

Ngakhale mutha kuwonjezera zowunikira pamalopo, nthawi zambiri sibwino kutetezedwa komanso kukhazikitsidwa kwa gulu lophwanyira dera. Izi zitha kukhala zowopsa ngati simukudziwa mapulagi ndi mababu omwe ali pagawo liti.

Pachifukwa ichi, m'nyumba zambiri, mawayawa amakhala oti mawaya ali pa dera limodzi ndipo magetsi ali mbali inayo.

Nthawi zina NEC imaletsa kugwiritsa ntchito mapulagi ndi nyali mudera lomwelo. Mwachitsanzo, m'mabafa ndi zida zazing'ono zakukhitchini zomwe zimalumikizidwa ndi socket pamwamba pa countertop.

Mutha kumangitsa nyali pakhoma, koma musanatero, muyenera kudziwa malamulo a National Electrical Code (NEC) ndi malamulo amdera lanu. Monga tanenera kale, mchitidwewu uli ndi malire, malingana ndi chipinda chomwe mukufuna kuchitira.

Kusakaniza zitsulo ndi zokonza sikovomerezeka chifukwa kumapangitsa makina opangira waya kukhala ovuta kwambiri kuposa momwe amafunikira.

Kufotokozera mwachidule

Palibe lamulo lolimba komanso lachangu la kuchuluka kwa malo omwe mungalumikizane ndi 15 amp circuit, koma muyenera kumangirira ma watts 1440 nthawi imodzi.

Apanso, ma 1.5 amps pachotuluka ndi lamulo labwino kwambiri. Komabe, muyenera kuyima pa 80% ya kuchuluka kwa ophwanya dera kuti wophwanya dera azikhalabe akugwira ntchito. Pa ma amps 15 timapereka malo opitilira 8.

Onani zina mwazolemba zathu pansipa.

• Momwe mungalumikizire chodulira dera
• Momwe mungayesere wowononga dera ndi multimeter
• Zizindikiro Zitatu Zochenjeza Zakuchulukira Kwa Magetsi

Ulalo wamavidiyo

Kodi mungaike malo angati pagawo limodzi?
