Kodi kukula kwa waya kwa 40 amp switch ndi chiyani
Zamkatimu
Pazida zambiri zokhala ndi mphamvu zambiri monga ma hobs, zowumitsira magetsi ndi masitovu amagetsi, mudzafunika 40 amp circuit breaker.
Kukhala ndi 40 amp circuit breaker kumathandiza kuteteza zida zanu zamagetsi. Koma ngati simusankha waya wokulirapo, mumayika pachiwopsezo chachitetezo cha mabwalo ndi zida. Chifukwa chake, ngati mukukumana ndi vuto posankha kukula kwa waya kwa 40 amp circuit breaker, ndili pano kuti ndikupatseni malangizo.
Nthawi zambiri, waya wamkuwa wa 8 AWG ndiye kukula kwa waya wochepera 40 amp circuit breaker. Komabe, waya wa 8 AWG ndioyenera kutalika kwa mapazi osakwana 100. Kapenanso, mutha kugwiritsanso ntchito waya wa 6 AWG.
Ndilowa mwatsatanetsatane pansipa.
Kukula kwa waya kwa 40 amp circuit breaker
Waya wamkuwa wa 8 AWG ndiye njira yoyenera kwambiri pa 40 amp circuit breaker. Titha kunena kuti waya ngati saizi yocheperako ya ma amps 40. Komabe, muyenera kuyang'ana zinthu ziwiri zotsatirazi.
Kutalika kwa mawaya
Ngati mukugwiritsa ntchito waya wa 8 AWG pa 40 amp circuit breaker, kutalika kwa waya kuyenera kukhala kosakwana mapazi 100. M'mabwalo amagetsi, kukana kumawonjezeka pamene kutalika kwa waya kumawonjezeka.
Malinga ndi lamulo la Ohm,
- V = Mphamvu yamagetsi
- I = flow
- R = kukana
Chifukwa chake, kutsika kwamagetsi kumasiyanasiyana ndi kukana.
Mwa kuyankhula kwina, ngati mutayendetsa 240 volts kupyolera mu waya wa 8 AWG kwa mapazi 50, simudzapeza 50 volts yonse pa phazi la 240. M'malo mwake, mudzapeza mtengo wotsika. Tinatcha kutsika kwamagetsi uku. Pali mtengo wovomerezeka pakutsika kwamagetsi uku. Muyenera kusunga kutsika kwamagetsi pansi pa 3% pakuwunikira ndi 5% pazida zina.
Mukathamanga 8 AWG waya 100 mapazi kapena kuposerapo, magetsi amatsika pansi pa mlingo woyenera. Izi zikachitika, chipangizo chamagetsi sichidzalandira mphamvu yofunikira. Izi zitha kuwononga zida zamagetsi.
Waya wazinthu zomangira
Kupatula kutalika, chinthu chachikulu chomwe muyenera kuganizira posankha 8 AWG waya ndi zinthu zomwe waya amapangidwa. Mwachitsanzo, mukamapempha mawaya 8 a AWG kuchokera ku sitolo ya hardware yapafupi, wogulitsa angakufunseni mtundu wa waya womwe mukufuna, aluminiyumu kapena mkuwa.
Pali chifukwa chabwino cha funsoli. Ngakhale kuti zonse zamkuwa ndi aluminiyumu ndizoyendetsa bwino kwambiri zamagetsi, mkuwa ndi chisankho chabwino kwambiri kuposa aluminiyumu. Copper ndiye woyendetsa bwino kwambiri.
Chifukwa chake pamagawo a 40A ndi 240V, waya wamkuwa wa 8 AWG ndi chisankho chabwino kwambiri. Komabe, ngati mugwiritsa ntchito aluminiyamu, mudzafunika waya wa 6 AWG wozungulira womwewo.
Kodi waya wamkuwa wa 6 AWG ndi woyenera 40 amp circuit breaker?
Zowonadi, waya wa 6 AWG ndiwabwino kwa 65 amp circuit breakers. Koma izi sizikutanthauza kuti simungagwiritse ntchito ndi 40 amp switch. Kugwiritsa ntchito waya wa 6 AWG kukupatsani mwayi wokula. Ngati ndi kotheka, mutha kusintha kusintha kwa 40 amp ndi 50 kapena 60 amps.
Langizo: Kugwiritsa ntchito waya wa 6 AWG pa 40 amp circuit breaker sikuphwanya malamulo a NEC.
Ndi ma amps angati omwe 40 amp circuit breaker angagwire?
Aliyense wophwanya dera amayamba kugwedezeka akafika mphamvu zambiri. Pakusintha kwa 40 amp, pakali pano ndi 40 amps. Chifukwa chake, chosinthiracho chidzapirira ma amps 40 popanda vuto lililonse. Koma katunduyo akamadutsa ma amps 40, kusinthako kumayenda.
Ngakhale ophwanya madera amatha kunyamula katundu wokwanira, malinga ndi NEC, mphamvu yayikulu iyenera kukhala 80%. Nazi zina za lamuloli.
Lamulo la 80% NEC
Ndi 80% yokha ya mphamvu zonse za wophwanya dera zomwe ziyenera kugwiritsidwa ntchito. Dera liyenera kukhalabe ndi malire awa kwa maola atatu kapena kupitilira apo.
Chifukwa chake ngati tilingalira kusintha kwa 40 amp,
Chifukwa chake, sungani katunduyo pamtunda wa 32 amp kwa 40 amp breakers. Gwiritsani ntchito chowotcha chokulirapo ngati dera lanu limakoka ma amps 32 pafupipafupi. Mwachitsanzo, 50 amp circuit breaker ingakhale chisankho chabwino.
Langizo: Ena ophwanya madera amavotera 100%.
Chifukwa chiyani ndiyenera kutsatira lamulo la NEC 80%?
Ngati dera likukokera katundu wambiri nthawi zonse, limatentha pakapita nthawi. Zomwezo zidzachitikanso ndi ophwanya madera. Chifukwa chake, oyendetsa madera amayamba kuyenda. Kapena kutentha kwambiri kungayambitse moto wamagetsi. (1)
Ndi ma watt angati omwe 40 amp switch imatha kugwira?
Nthawi zonse tikamawerengera mphamvu, timagwiritsa ntchito lamulo la Joule.
Tikaganizira za 40 amp, 240 V magetsi:
Mwamwayi mphamvu = 40 × 240 = 9600 Watts.
Koma simungagwiritse ntchito mphamvu yayikulu kwambiri yamagetsi ozungulira. Muyenera kugwiritsa ntchito 80%.
Choncho,
Mphamvu (kutengera mphamvu ya 80%) \u40d 80 × 240% × 7680 \uXNUMXd XNUMX Watts.
Mwachitsanzo, kusintha kwa 40 amp (80% voted) kumatha kugwira mpaka 7680 Watts. Ngati wophwanya dera adavotera 100%, amatha kugwira 9600W.
Kumbukirani: Kaya mukugwiritsa ntchito 80% kapena 100% yovotera dera, waya 8 AWG ndi chisankho chabwino pamabwalo omwe ali pamwambapa.
Kodi mumadziwa bwanji kukula kwa waya?
American Wire Gauge, yomwe imadziwikanso kuti AWG, ndiye mulingo waku North America wama waya. Izi zidzatipatsa kulingalira malinga ndi kukula kwa waya ndi katundu amene waya wina anganyamule.
Nambala yofananira idzasindikizidwa pazitsulo za waya. Kulembako kudzawonetsa 4 AWG, 6 AWG, 8 AWG, 10 AWG, ndi zina zotero. Kuchokera pazithunzizi, mukhoza kuwerengera kukula kwa waya ndi zamakono zomwe waya amatha kudutsa.
Mwachitsanzo, waya wa 12 AWG ndi mainchesi 0.0808 m'mimba mwake ndi waya wa 6 AWG ndi mainchesi 0.162 m'mimba mwake.
Monga mukuonera, ndi chiwerengero chapamwamba cha geji, makulidwe a waya amawonjezeka.
Kodi mainchesi a waya amaphatikizanso kutsekereza?
Opanga mawaya a AWG samaphatikiza kutsekereza waya mu kukula kwa waya. Choncho, m'mimba mwake wa waya ndi awiri a kondakitala.
Nanga bwanji ngati sindikuwona mlingo pakutsekera kwa waya?
Ngati simukuwona mavoti pa kutsekereza waya, gwiritsani ntchito digito caliper kuyeza makulidwe a waya. Nawa kalozera wosavuta momwe mungachitire.
- Choyamba chotsani waya womwe mukufuna kuyeza.
- Kenako ikani kondakitala wopanda pansagwada yokhazikika ya digito caliper.
- Kenako, bweretsani nsagwada zosunthika ku waya.
- Pambuyo pake, pezani zowerengera pazithunzi za digito.
- Pomaliza, gwiritsani ntchito tchati cha kukula kwa waya cha AWG kuti mupeze mavoti oyenera a wayawo.
Gwiritsani ntchito ulalowu pamasaizi a waya a AWG.
Langizo: Ma caliper ena amatha kuwonetsa sikelo mu millimeters. Ndipo zina zidzawonekera mu mainchesi.
Nawa mawaya amkuwa omwe amapezeka ndi ma diameter awo komanso ma amperage.
| waya gauge | Diameter ( mainchesi) | Adavoteledwa pano |
| 12 awg | 0.0808 | 20 amplifiers |
| 10 awg | 0.1019 | 30 amplifiers |
| 8 awg | 0.1285 | 40 amplifiers |
| 6 awg | 0.1620 | 65 amplifiers |
Kufotokozera mwachidule
Kwa khitchini yamakono, kukhala ndi dera lodalirika lamagetsi ndilofunika kwambiri. Simupeza magetsi abwino popanda kukula kwa waya. Chifukwa chake, mukamagwiritsa ntchito 40 amp circuit breaker kunyumba, onetsetsani kuti mukugwiritsa ntchito waya wa 8 AWG kapena 6 AWG. Idzakutetezani inu ndi zida zanu zapakhomo. (2)
Onani zina mwazolemba zathu pansipa.
- Komwe mungapeze waya wandiweyani wamkuwa wa zidutswa
- Waya wanji wa 30 amps 200 mapazi
- Momwe mungayendetsere waya kudutsa makoma mopingasa
